12 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet 2. overview 2.1 general description the spansion S25FL128S and s25fl2 56s devices are flash non-volatile memory products using: ? mirrorbit technology - that stores two da ta bits in each memory array transistor ? eclipse architecture - that dramatically improves program and erase performance ? 65 nm process lithography this family of devices connect to a host system via a serial peripheral interface (spi). traditional spi single bit serial input and output (single i/o or sio) is sup ported as well as optional two bit (dual i/o or dio) and four bit (quad i/o or qio) serial commands. this mult iple width interface is called spi multi-i/o or mio. in addition, the fl-s family adds support for double da ta rate (ddr) read command s for sio, dio, and qio that transfer address and read data on both edges of the clock. the eclipse architecture features a page programming bu ffer that allows up to 128 words (256 bytes) or 256 words (512 bytes) to be programmed in one operati on, resulting in faster effective programming and erase than prior generation spi program or erase algorithms. executing code directly from flash me mory is often called execute-in-place or xip. by using fl-s devices at the higher clock rates supported, with qio or ddr-qio commands, the in struction read transfer rate can match or exceed traditional parallel interface, asynchronous, nor flash memories while reducing signal count dramatically. the S25FL128S and s25fl256s produ cts offer high densities coupled with the flexibility and fast performance required by a variety of embedded applicat ions. they are ideal for code shadowing, xip, and data storage.

16 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet hardware interface serial peripheral interface with multiple input / output (spi-mio) many memory devices connect to their host system with separate parallel control, address, and data signals that require a large number of signal connections and la rger package size. the large number of connections increase power consumption due to so many signals switching and the larger package increases cost. the S25FL128S and s25fl256s devices reduce the number of signals for connection to the host system by serially transferring all control, addres s, and data information over 4 to 6 signals. this reduces the cost of the memory package, reduces signal switching power, and eith er reduces the host connection count or frees host connectors for use in providing other features. the S25FL128S and s25fl256s devic es use the industry standard single bit serial peripheral interface (spi) and also supports optional extension commands for two bit (dual) and four bit (quad) wide serial transfers. this multiple width interf ace is called spi multi-i/o or spi-mio. 3. signal descriptions 3.1 input/output summary table 3.1 signal list signal name type description reset# input hardware reset: low = device resets and returns to standby state, ready to receive a command. the signal has an internal pull-up resistor and may be left unconnected in the host system if not used. sck input serial clock cs# input chip select si / io0 i/o serial input for single bit data commands or io0 for dual or quad commands. so / io1 i/o serial output for single bit data commands. io1 for dual or quad commands. wp# / io2 i/o write protect when not in quad mode. io2 in quad mode. the signal has an internal pull-up resistor and may be left unconnected in the host system if not used for quad commands. hold# / io3 i/o hold (pause) serial transfer in single bit or dual data commands. io3 in quad-i/o mode. the signal has an internal pull-up resistor and may be left unconnected in the host system if not used for quad commands. v cc supply core power supply. v io supply versatile i/o power supply. v ss supply ground. nc unused not connected. no device internal signal is connec ted to the package connector nor is there any future plan to use the connecto r for a signal. the connection may safely be used for routing space for a signal on a printe d circuit board (pcb). however, any signal connected to an nc must not have voltage levels higher than v io . rfu reserved reserved for future use. no device internal signal is currently connected to the package connector but there is potential future use of the connector for a signal. it is recommended to not use rfu connectors for pcb routing channels so that the pcb may take advantage of future enhanced features in compatible footprint devices. dnu reserved do not use. a device internal signal may be c onnected to the package connector. the connection may be used by spansion for test or other purposes and is not intended for connection to any host system signal. any dnu si gnal related function will be inactive when the signal is at v il . the signal has an internal pull-down resistor and may be left unconnected in the host system or may be tied to v ss . do not use these connections for pcb signal routing channels. do not connect any host system signal to this connection.
july 12, 2012 S25FL128S_256s_00_05 S25FL128S and s25fl256s 17 data sheet 3.2 address and data configuration traditional spi single bit wide commands (single or sio) send information from the host to the memory only on the si signal. data may be sent back to the host serially on the serial output (so) signal. dual or quad output commands send information from th e host to the memory only on the si signal. data will be returned to the host as a sequence of bit pairs on io0 and io1 or four bit (nibble) groups on io0, io1, io2, and io3. dual or quad input/output (i/o) commands send informa tion from the host to the memory as bit pairs on io0 and io1 or four bit (nibble) groups on io0, io1, io2, and io3. data is returned to the host similarly as bit pairs on io0 and io1 or four bit (nibble) groups on io0, io 1, io2, and io3. 3.3 reset# the reset# input provides a hardware method of resetti ng the device to standby state, ready for receiving a command. when reset# is driven to logic low (v il ) for at least a period of t rp , the device: ? terminates any operation in progress, ? tristates all outputs, ? resets the volatile bits in the configuration register, ? resets the volatile bits in the status registers, ? resets the bank address register to zero, ? loads the program buffer with all ones, ? reloads all internal configuration information necessary to bring the device to standby mode, ? and resets the internal cont rol unit to standby state. reset# causes the same initialization process as is performed when power comes up and requires t pu time. reset# may be asserted low at any ti me. to ensure data integrity any operation that was interrupted by a hardware reset should be reinitiated once the device is ready to accept a command sequence. when reset# is first asserted low, the device draws i cc1 (50 mhz value) during t pu . if reset# continues to be held at v ss the device draws cm os standby current (i sb ). reset# has an internal pull-up resi stor and may be left unconnected in the host system if not used. the reset# input is not available on all packages op tions. when not available the reset# input of the device is tied to the inactive state, inside the package. 3.4 serial clock (sck) this input signal provides the synchronization reference fo r the spi interface. instructions, addresses, or data input are latched on the rising edge of the sck signal. da ta output changes after the falling edge of sck, in sdr commands, and after every edge in ddr commands. 3.5 chip select (cs#) the chip select signal indicates when a command for the device is in process and the other signals are relevant for the memory device. when the cs# signal is at the logic high state, the device is not selected and all input signals are ignored and all output signals are high impedance. unless an internal program, erase or write registers (wrr) embedded operation is in prog ress, the device will be in the standby power mode. driving the cs# input to logic low st ate enables the device, placing it in the active power mode. after power- up, a falling edge on cs# is required prior to the start of any command.
18 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet 3.6 serial input (si) / io0 this input signal is used to transfer data serially into the device. it receives instructions, addresses, and data to be programmed. values are latched on the rising edge of serial sck clock signal. si becomes io0 - an input and output during dual and quad commands for receiving instructions, addresses, and data to be programmed (values latched on rising edge of serial sck clock signal) as well as shifting out data (on the falling edge of sck, in sdr comma nds, and on every edge of sck, in ddr commands). 3.7 serial output (so) / io1 this output signal is used to transfer data serially out of the device. data is shifted out on the falling edge of the serial sck clock signal. so becomes io1 - an input and output during dual and quad commands for receiving addresses, and data to be programmed (values latched on rising edge of serial sck clock signal) as well as shifting out data (on the falling edge of sck, in sdr commands, a nd on every edge of sck, in ddr commands). 3.8 write protect (wp#) / io2 when wp# is driven low (v il ), during a wrr command and while the st atus register write disable (srwd) bit of the status register is set to a 1, it is not possibl e to write to the status and configuration registers. this prevents any alteration of the block protect (bp2, bp1, bp0) and tbprot bits of the status register. as a consequence, all the data bytes in the memory area that are protected by the block protect and tbprot bits, are also hardware protected against data mo dification if wp# is low during a wrr command. the wp# function is not available w hen the quad mode is enabled (cr[1]=1). the wp# function is replaced by io2 for input and output during quad mode for re ceiving addresses, and data to be programmed (values are latched on rising edge of the sck signal) as well as shifting out data (on the falling edge of sck, in sdr commands, and on every edge of sck, in ddr commands). wp# has an internal pull-up resistor ; when unconnected, wp# is at v ih and may be left unconnected in the host system if not used for quad mode. 3.9 hold (hold#) / io3 the hold (hold#) signal is used to pause any serial communications with the device without deselecting the device or stopping the serial clock. to enter the hold condition, the devi ce must be selected by driving the cs # input to the logic low state. it is recommended that the user keep the cs# input low state during the entire duration of the hold condition. this is to ensure that the state of t he interface logic remains unchanged from the moment of entering the hold condition. if the cs# input is driven to the logic high state while the device is in the hold condition, the interface logic of the device will be re set. to restart communication with t he device, it is necessary to drive hold# to the logic high state while driving the cs# signa l into the logic low state. this prevents the device from going back into the hold condition. the hold condition starts on the falling edge of the ho ld (hold#) signal, provided that this coincides with sck being at the logic low state. if the falling edge does not coincide with the sck signal being at the logic low state, the hold condition starts whenever the sck signal reaches the logic low state. taking the hold# signal to the logic low state does not terminate any writ e, program or erase operation that is currently in progress. during the hold condition, so is in high imped ance and both the si and sck input are don't care. the hold condition ends on the rising edge of the hold (hold#) signal, provided that this coincides with the sck signal being at the logic low state. if the rising edge does not coincide with the sck signal being at the logic low state, the hold condition ends whenever the sck signal reaches the logic low state. the hold# function is not available when the quad m ode is enabled (cr1[1] =1). the hold function is replaced by io3 for input and output during quad mode for receiving addresses, and data to be programmed (values are latched on rising edge of the sck signal) as well as shifting out data (on the falling edge of sck, in sdr commands, and on every edge of sck, in ddr commands).

54 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet software interface this section discusses the features and behaviors most re levant to host system software that interacts with S25FL128S and s25fl256s memory devices. 8. address space maps 8.1 overview 8.1.1 extended address the S25FL128S and s25fl256s devices support 32-bit addresses to enable higher density devices than allowed by previous generation (legacy) spi devices t hat supported only 24-bit addresses. a 24-bit byte resolution address can a ccess only 16 mbytes (128 mbits) of ma ximum density. a 32-bit byte resolution address allows direct addressing of up to a 4 gbytes (32 gbits) of address space. legacy commands continue to support 24-bit addresses for backward software compatibility. extended 32-bit addresses are enabled in three ways: ? bank address register ? a software (command) loadable in ternal register that supplies the high order bits of address when legacy 24-bit addresses are in use. ? extended address mode ? a bank address register bit t hat changes all legacy commands to expect 32 bits of address supplied fr om the host system. ? new commands ? that perform both legacy and new functions, which expect 32-bit address. the default condition at power-up and after reset, is th e bank address register loaded with zeros and the extended address mode set for 24-bit addresses. this enabl es legacy software compatible access to the first 128 mbits of a device. the S25FL128S device supports the ex tended address features in the same way but in essence ignores bits 31 to 24 of any address because the main flash array onl y needs 24 bits of address. this enables simple migration from the 128-mb density to higher density devices without changing the address handling aspects of software. 8.1.2 multiple address spaces many commands operate on the main flash memory array. some commands operate on address spaces separate from the main flash array. each separate address space uses the full 32-bit address but may only define a small portion of the available address space. 8.2 flash memory array the main flash array is divided into erase units called sectors. the sectors are organized either as a hybrid combination of 4-kb and 64-kb sectors, or as uniform 256-kbyte sectors. the sector organization depends on the device model selected, see ordering information on page 149 . table 8.1 s25fl256s sector and memory addr ess map, bottom 4-kbyte sectors sector size (kbyte) sector count sector range address range (byte address) notes 4 32 sa00 00000000h-00000fffh sector starting address ? sector ending address : : sa31 0001f000h-0001ffffh 64 510 sa32 00020000h-0002ffffh : : sa541 01ff0000h-01ffffffh

58 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet 8.5 registers registers are small groups of memory cells used to configure how the s25fl-s memory device operates or to report the status of device operations. the regist ers are accessed by specific commands. the commands (and hexadecimal instruction codes) used for each register are noted in each register description. the individual register bits may be volatile, non-volatile, or one time programmable (otp ). the type for each bit is noted in each register description. the default stat e shown for each bit refers to the state after power-on reset, hardware reset, or software reset if the bit is volatile. if the bit is non-volatile or otp, the default state is the value of the bit when the device is shipped from spansion. non-volatile bits have the same cycling (erase and program) endurance as the main flash array. 8.5.1 status register 1 (sr1) related commands: read status register (rdsr1 0 5h), write registers (wrr 01h), write enable (wren 06h), write disable (wrdi 04h), cle ar status register (clsr 30h). the status register contains both status and control bits: status register write disable (srwd) sr1[7] : places the device in the hardware protected mode when this bit is set to 1 and the wp# input is driven low. in this mode, the srwd, bp2, bp1, and bp0 bits of the status register become read-only bits and the writ e registers (wrr) command is no longer accepted for execution. if wp# is high the srwd bit and bp bits may be changed by the wrr command. if srwd is 0, wp# has no effect and the srwd bit and bp bits may be changed by the wrr command. the srwd bit has the same non-volatile endurance as the main flash array. program error (p_err) sr1[6] : the program error bit is used as a program operation success or failure indication. when the program error bit is set to a 1 it indicates that there was an error in the last program operation. this bit will also be set when the user attemp ts to program within a protected main memory sector or locked otp region. when the program error bit is set to a 1 this bit can be reset to 0 with the clear status register (clsr) command. this is a read-only bit and is not affected by the wrr command. erase error (e_err) sr1[5] : the erase error bit is used as an erase operation success or failure indication. when the erase error bit is set to a 1 it indica tes that there was an error in the last erase operation. this bit will also be set when the user attempts to erase an individual protected main memory sector. the bulk erase command will not set e_err if a protected sector is found during the command execution. when the erase error bit is set to a 1 this bit can be reset to 0 with the clear status r egister (clsr) command. this is a read-only bit and is not affected by the wrr command. table 8.8 status register-1 (sr1) bits field name function type default state description 7 srwd status register write disable non-volatile 0 1 = locks state of srwd, bp, and configuration register bits when wp# is low by ignoring wrr command 0 = no protection, even when wp# is low 6 p_err programming error occurred volatile, read only 0 1 = error occurred. 0 = no error 5 e_err erase error occurred volatile, read only 0 1 = error occurred 0 = no error 4 bp2 block protection volatile if cr1[3]=1, non-volatile if cr1[3]=0 1 if cr1[3]=1, 0 when shipped from spansion protects selected range of sectors (block) from program or erase 3 bp1 2 bp0 1 wel write enable latch volatile 0 1 = device accepts write registers (wrr), program or erase commands 0 = device ignores write registers (wrr), program or erase commands this bit is not affected by wrr, only wren and wrdi commands affect this bit 0 wip write in progress volatile, read only 0 1 = device busy, a write registers (wrr), program, erase or other operation is in progress 0 = ready device is in standby mode and can accept commands

60 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet latency code (lc) cr1[7:6]: the latency code selects the number of mode and dummy cycles between the end of address and the start of re ad data output for all read commands. some read commands send mode bits following the addre ss to indicate that the next command will be of the same type with an implied, rather than an explicit, instruction. the next command thus does not provide an instruction byte, only a new address and mode bits. this reduces the time needed to send each command when the same command type is repeated in a sequence of commands. dummy cycles provide additional latency that is needed to complete the initial read access of the flash array before data can be returned to the host system. some read commands require additional latency cycles as the sck frequency is increased. the following latency code tables provide different la tency settings that are conf igured by spansion. the high performance versus the enhanced high performance se ttings are selected by the ordering part number. where mode or latency (dummy) cycles are shown in the tables as a dash, that read command is not supported at the frequency shown. r ead is supported only up to 50 mhz but the same latency value is assigned in each latency code and the command may be used when the device is operated at ? 50 mhz with any latency code setting. similarly, only the fast read command is supported up to 133 mhz but the same 10b latency code is used for fast read up to 133 mhz and for the other dual and quad read commands up to 104 mhz. it is not necessary to change the latency code from a higher to a lower frequency when operating at lower frequencies where a particular command is suppor ted. the latency code values for a higher frequency can be used for accesses at lower frequencies. the high performance settings provide latency options that are the same or faster than alternate source spi memories. these settings provide mode bits only for the quad i/o read command. the enhanced high performance settings similarly provide latency options the same or faster than additional alternate source spi memories and adds mode bits for the dual i/o read, ddr fast read, and ddr dual i/o read commands. read ddr data learning pattern (dlp) bits may be plac ed within the dummy cycles immediately before the start of read data, if there ar e 5 or more dummy cycles. see read memory array commands on page 92 for more information on the dlp. table 8.10 latency codes for sdr high performance freq.

july 12, 2012 S25FL128S_256s_00_05 S25FL128S and s25fl256s 69 data sheet the selection of the ppb lock bit management met hod is made by programming otp bits in the asp register so as to permanently select the method used. 9.4.1 asp register the asp register is used to permanently configur e the behavior of advanced sector protection (asp) features. see table 8.17, asp register (aspr) on page 64 . as shipped from the factory, all dev ices default asp to the persistent protection mode, with all sectors unprotected, when power is applied. the device program mer or host system must then choose which sector protection method to use. progra mming either of the, one-time programmable, protection mode lock bits, locks the part permanently in the selected mode: ? aspr[2:1] = 11 = no asp mode selected, persistent protection mode is the default. ? aspr[2:1] = 10 = persistent prot ection mode permanently selected. ? aspr[2:1] = 01 = password protec tion mode permanently selected. ? aspr[2:1] = 00 = ill egal condition, attempting to program both bits to zero resu lts in a programming failure. asp register prog ramming rules: ? if the password mode is chosen, the password must be programmed prior to setting the protection mode lock bits. ? once the protection mode is selected, the protec tion mode lock bits are permanently protected from programming and no further changes to the asp register is allowed. the programming time of the asp register is the sa me as the typical page pr ogramming time. the system can determine the status of the asp register programming operation by reading the wip bit in the status register. see status register 1 (sr1) on page 58 for information on wip. after selecting a sector protection method, each se ctor can operate in each of the following states: ? dynamically locked ? a sector is protect ed and can be changed by a simple command. ? persistently locked ? a sector is protected and cannot be changed if its ppb bit is 0. ? unlocked ? the sector is unprotected and can be changed by a simple command. 9.4.2 persistent protection bits the persistent protecti on bits (ppb) are located in a separate nonvolatile flash a rray. one of the ppb bits is related to each sector. when a ppb is 0, its related se ctor is protected from pr ogram and erase operations. the ppb are programmed individually but must be erased as a group, similar to the way individual words may be programmed in the main array but an entire sector must be erased at the same time. the ppb have the same program and erase endurance as the main flash me mory array. preprogramming and verification prior to erasure are handled by the device. programming a ppb bit requires the typical page progra mming time. erasing all the ppbs requires typical sector erase time. during ppb bit pr ogramming and ppb bit erasing, status is available by reading the status register. reading of a ppb bit requires th e initial access time of the device. notes: 1. each ppb is individually programmed to 0 and all are erased to 1 in parallel. 2. if the ppb lock bit is 0, the ppb program or ppb erase command does not execute and fails without programming or erasing the ppb. 3. the state of the ppb for a given sector can be verified by using the ppb read command. 9.4.3 dynamic protection bits dynamic protection bits are volatile and unique for each sector and can be individually modified. dyb only control the protection for sectors t hat have their ppb set to 1. by issu ing the dyb write command, a dyb is cleared to 0 or set to 1, thus placing each sector in the protected or unprotecte d state respectively. this feature allows software to easily protect sectors agai nst inadvertent changes, yet does not prevent the easy removal of protection when changes are needed. the dybs can be set or cleared as often as needed as they are volatile bits.

72 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet 10. commands all communication between the host system and s25f l128s and s25fl256s memory devices is in the form of units called commands. all commands begin with an instruction that selects the ty pe of information transfer or device operation to be performed. commands may also have an address, instruct ion modifier, latency period, data transfer to the memory, or data transfer from the memory. all instru ction, address, and data information is transferred serially between the host system and memory device. all instructions are transferred from host to memory as a single bit serial sequence on the si signal. single bit wide commands may provide an address or data sent only on the si signal. data may be sent back to the host serially on so signal. dual or quad output commands provide an address sent to the memory only on the si signal. data will be returned to the host as a sequence of bit pairs on io0 and io1 or four bit (nibble) groups on io0, io1, io2, and io3. dual or quad input/output (i/o) commands provide an ad dress sent from the host as bit pairs on io0 and io1 or, four bit (nibble) groups on io0, io1, io2, and io3. data is returned to the host similarly as bit pairs on io0 and io1 or, four bit (nibble) groups on io0, io1, io2, and io3. commands are structured as follows: ? each command begins with an eight bit (byte) instruction. ? the instruction may be stand alone or may be followed by address bits to select a location within one of several address spaces in the device. the address may be either a 24-bit or 32-b it byte boundary address. ? the serial peripheral interface with multiple io pr ovides the option for each transfer of address and data information to be done one, two, or four bits in parallel. this enables a trade off between the number of signal connections (io bus width) and the speed of information transfer. if the host system can support a two or four bit wide io bus the memory performance can be increased by usi ng the instructions that provide parallel two bit (dual) or parallel four bit (quad) transfers. ? the width of all transfers following the instru ction are determined by the instruction sent. ? all single bits or parallel bit groups are tran sferred in most to least significant bit order. ? some instructions send instruction modifier (mode) bits following the address to indicate that the next command will be of the same type with an implied, rather than an explicit, instruction. the next command thus does not provide an instruction byte, only a new address and mode bits. this reduces the time needed to send each command when the same command ty pe is repeated in a sequence of commands. ? the address or mode bits may be followed by write data to be stored in the memory device or by a read latency period before read data is returned to the host. ? read latency may be zero to several sck cycles (also referred to as dummy cycles). ? all instruction, address, mode, and data information is transferred in byte granularity. addresses are shifted into the device with the most significant byte first. a ll data is transferred with t he lowest address byte sent first. following bytes of data are sent in lowest to highest byte address order i.e. the byte address increments. ? all attempts to read the flash memory array duri ng a program, erase, or a write cycle (embedded operations) are ignored. the embedded operation will c ontinue to execute without any affect. a very limited set of commands are accepted during an embedded operation. these are discussed in the individual command descriptions. while a program, eras e, or write operation is in progress, it is recommended to check that the write-in progress (w ip) bit is 0 before issuing most commands to the device, to ensure the new command can be accepted. ? depending on the command, the time for execution varies. a command to read status information from an executing command is available to determine when the command completes execution and whether the command was successful. ? although host software in some cases is used to di rectly control the spi interface signals, the hardware interfaces of the host system and the memory device generally handle the details of signal relationships and timing. for this reason, signal relationships and timing are not covered in detail within this software interface focused section of the docu ment. instead, the focus is on the l ogical sequence of bits transferred

some commands transfer address or data on each risi ng edge of sck. these are called single data rate commands (sdr). ? some sdr commands transfer address one bit per rising edge of sck and return data 1, 2, or 4 bits of data per rising edge of sck. these are called read or fast read for 1-bit data; dual output read for 2-bit data, and quad output for 4-bit data. ? some sdr commands transfer both address and data 2 or 4 bits per rising edge of sck. these are called dual i/o for 2 bit and quad i/o for 4 bit. ? some commands transfer address and data on both th e rising edge and falling edge of sck. these are called double data rate (ddr) commands. ? there are ddr commands for 1, 2, or 4 bits of addr ess or data per sck edge. these are called fast ddr for 1-bit, dual i/o ddr for 2-bit, and quad i/o ddr for 4-bit per edge transfer. all of these commands begin with an in struction code that is transferred one bit per sck rising edge. the instruction is followed by either a 3- or 4-byte address transferred at sdr or ddr. commands transferring address or data 2 or 4 bits per clock edge are called multiple i/o (mio) commands. for fl-s devices at 256 mbits or higher density, the traditi onal spi 3-byte addresses are unable to directly address all locations in the memory array. these device have a bank address r egister that is used with 3-byte address commands to supply the high order address bits beyond the addre ss from the host system. the default bank address is zero. commands are provided to load and read the bank address register. these devices may also be configured to take a 4-byte address from the host system wit h the traditiona l 3-byte address commands. the 4-byte address mode for traditional commands is activat ed by setting the external address (extadd) bit in the bank address register to 1. in the fl128s, higher order address bits above a23 in the 4-byte address commands, commands using extended ad dress mode, and the bank address register are not relevant and are ignored because the flash array is only 128 mbits in size. the quad i/o commands provide a performance improvem ent option controlled by mode bits that are sent following the address bits. the mode bits indicate whet her the command following the end of the current read will be another read of the same type, without an instru ction at the beginning of the read. these mode bits give the opti on to eliminate the instruct ion cycles when doing a series of quad i/o read accesses. a device ordering option provides an enhanced high pe rformance option by adding a similar mode bit scheme to the ddr fast read, dual i/o, and dual i/o ddr commands, in addition to the quad i/o command. some commands require delay cycles foll owing the address or mode bits to allow time to access the memory array. the delay cycles are traditio nally called dummy cycles. the dummy cycles are ignored by the memory thus any data provided by th e host during these cycles is ?don?t care ? and the host may also leave the si signal at high impedance during the dummy cycles. when mio commands are us ed the host must stop driving the io signals (outputs are high impedance) before the end of last dummy cycle. when ddr commands are used the host must not drive the i/o signals during any dummy cycle. the number of dummy cycles varies with the sck frequency or performance option selected via t he configuration r egister 1 (cr1) latency code (lc). dummy cycles are measured from sck falling edge to next sck falling edge. spi outputs are traditionally driven to a new value on the falli ng edge of each sck. zero dummy cycles means the returning data is driven by the memory on the same fa lling edge of sck that the host stops driving address or mode bits. the ddr commands may optionally have an 8-edge data learning pattern (dlp) driven by the memory, on all data outputs, in the dummy cyc les immediately before the start of data. the dlp can help the host memory controller determine the phase shift from sck to data edges so that the memory controller can capture data at the c enter of the data eye. when using sdr i/o commands at higher sck frequenc ies (>50 mhz), an lc that provides 1 or more dummy cycles should be selected to allow additional time for the host to stop drivin g before the memory starts driving data, to minimize i/o driver conflict. when using ddr i/o commands with the dlp enabled, an lc that provides 5 or more dummy cycles should be sele cted to allow 1 cycle of additional time for the host to stop driving before the memory starts driving the 4 cycle dlp. each read command ends when cs# is returned high at any point during data return. cs# must not be returned high during the mode or dummy cycles before data returns as this may cause mode bits to be

(?x?) and may be high impedance. if the mode bits equal axh, then the device remains in dual i/o enhanced high performa nce read mode and the next address can be entered (after cs# is raised high and then asserted low) without the bbh or bch instruction, as shown in figure 10.36 ; thus, eliminating eight cycles for the command seq uence. the follo wing sequences will release the device from dual i/o enhanced high performance read mode; after which, the device can accept standard spi commands: 0 1 2 3 4 5 6 7 8 38 3 9 40 41 42 4 3 44 45 46 47 in s tr u ction 3 2 bit addre ss d a t a 1 d a t a 2 d a t a 3 d a t a 3 7 6 5 4 3 2 1 0 3 1 1 0 4 0 4 0 4 0 4 0 5 1 5 1 5 1 5 1 6 2 6 2 6 2 6 2 7 3 7 3 7 3 7 3 c s # s clk io0 io1 io2 io 3

io0 (si) and io1 (so). it is similar to the dual i/o read command but transfers tw o address, mode, or data bits on every edge of the clock. in some applications, the redu ced instruction overhead might allo w for code execution (xip) directly from S25FL128S and s25fl256s devices. the maximum operating clock frequency for ddr dual i/o read command is 66 mhz. for ddr dual i/o read commands, there is a latency requi red after the last address bits are shifted into io0 and io1, before data begins shifting out of io0 and io 1. there are different orderi ng part numbers that select the latency code table used for this command, either t he high performance lc (hplc) table or the enhanced high performance lc (ehplc) table. the number of latency (dummy) clocks is determined by the frequency of sck (refer to table 8.11, latency codes for ddr high performance on page 60 or table 8.13, latency codes for ddr enhanced high performance on page 61 ). the number of dummy cycles is set by the lc bits in the configuration register (cr1). the hplc table does not provide cycles for mode bits so each dual i/o command starts with the 8 bit instruction, followed by address, followed by a latency period. this latency period allows the device?s internal circuitry enough time to access the initial address. du ring these latency cycles, the data value on si (io0) and so (io1) are ?don?t care? and may be high impedance. when the data learning pattern (dlp) is enabled the host system must not drive the io signals during the dummy cycles. the io signals must be left high impedance by the host so that the memory devi ce can drive the dlp during the dummy cycles. the ehplc table does provide cycles for mode bits so a series of dual i/o ddr commands may eliminate the 8 bit instruction after the first command sends a complementary mode bit pattern, as shown in figure 10.46 and figure 10.48 on page 106 . this added feature removes the need for the eight bit sdr instruction sequence and dramatically reduces initial access times (improves xip performance). the mode bits control the length of the next ddr dual i/o read operation through the inclusion or exclusion of the first byte instruction code. if the upper nibble (io[7:4] ) and lower nibble (io[3: 0]) of the mode bits are complementary (i.e. 5h and ah) the device transitions to continuous ddr dual i/o read mode and the next address can be entered (after cs# is raised high and t hen asserted low) without requiring the bdh or beh instruction, as shown in figure 10.47 on page 106 , and thus, eliminating ei ght cycles from the command sequence. the following sequences will release the dev ice from continuous ddr dual i/o read mode; after which, the device can accept standard spi commands: 1. during the ddr dual i/o read command sequence, if the mode bits are not complementary the next time cs# is raised high and then asserted low the device will be released from ddr dual i/o read mode. 2. during any operation, if cs# toggles high to low to high for eight cycles (or less) and data input (io0 and io1) are not set for a valid instruction sequence, then the device will be released from ddr dual i/o read mode. the address can start at any byte location of the memo ry array. the address is automatically incremented to the next higher address in sequential order after each byte of data is shifted out. the entire memory can therefore be read out with one single read inst ruction and address 000000h provided. when the highest address is reached, the address counter will wrap around and roll back to 000000h, allowing the read sequence to be continued indefinitely. cs# should not be driven high during mode or dummy bi ts as this may make the mode bits indeterminate. the hold function is not valid during dual i/o ddr commands. note that the memory devices may drive the ios with a pr eamble prior to the first data value. the preamble is a data learning pattern (dlp) that is used by the ho st controller to optimize data capture at higher frequencies. the preamble dlp drives the io bus for the four clock cycles immediately before data is output. the host must be sure to stop driving the io bus prior to the time that the memo ry starts outputting the preamble. the preamble is intended to give the host controller an indication about the round trip time from when the host drives a clock edge to when the corresponding data value returns from the memory device. the host controller will skew the data capture point during the pr eamble period to optimize timing margins and then use the same skew time to capture the data during the rest of the read operation. the optimized capture point will be determined during the preamble period of every read oper ation. this optimization strategy is intended to

108 S25FL128S and s25fl256s S25FL128S_256s_00_05 july 12, 2012 data sheet the preamble is intended to give the host controller an indication about the round trip time from when the host drives a clock edge to when the corresponding data value returns from the memory device. the host controller will skew the data capture point during the pr eamble period to optimize timing margins and then use the same skew time to capture the data during the rest of the read operation. the optimized capture point will be determined during the preamble period of every read oper ation. this optimization strategy is intended to compensate for both the pvt (process, voltage, temper ature) of both the memory device and the host controller as well as any syst em level delays caused by flight time on the pcb. although the data learning pattern (dlp) is programma ble, the following example shows example of the dlp of 34h. the dlp 34h (or 00110100) will be driven on eac h of the active outputs (i.e. all four sios on a x4 device, both sios on a x2 device and the single so output on a x1 device). this pattern was chosen to cover both dc and ac data transition scenari os. the two dc transition scenarios include data low for a long period of time (two half clocks) followed by a high going tr ansition (001) and the comple mentary low going transition (110). the two ac transition scenarios include data low for a short period of time (one half clock) followed by a high going transition (101) and the complementary low going transition (010). the dc transitions will typically occur with a starting point cl oser to the supply rail than the ac transitions that may not have fully settled to their steady state (dc) levels. in many case s the dc transitions will bound the beginning of the data valid period and the ac transitions will bound the ending of the data valid period. these transitions will allow the host controller to identify the beginning and ending of the valid data eye. once the data eye has been characterized the optimal data capture point can be chosen. see spi ddr data learning registers on page 65 for more details. figure 10.49 ddr quad i/o read initial access (3-byte address, edh [extadd=0], hplc=11b) figure 10.50 continuous ddr quad i/o read subsequent access (3-byte address,hplc=11b) 0 1 2 3 4 5 6 7 8 9 10 11 12 1 3 14 15 16 in s tr u ction add re ss mo d e high-z b us t u rn- a ro u nd d a t a 0 d a t a 1 8 cycle s 3 cycle s 1 cycle 3 cycle d u mmy 1 cycle per d a t a 7 6 5 4 3 2 1 0 20 16 12 8 4 0 4 0 4 0 4 0 21 17 1 3 9 5 1 5 1 5 1 5 1 22 1 8 14 10 6 2 6 2 6 2 6 2 2 3 19 15 11 7 3 7 3 7 3 7 3 c s # s clk io0 io1 io2 io 3 0 1 2 3 4 5 6 7 8 addre ss mode high-z b us t u rn- a ro u nd d a t a 0 d a t a 1 3 cycle 1 cycle 3 cycle d u mmy 1 cycle per d a t a 20 16 12 8 4 0 4 0 4 0 4 0 21 17 1 3 9 5 1 5 1 5 1 5 1 22 1 8 14 10 6 2 6 2 6 2 6 2 2 3 19 15 11 7 3 7 3 7 3 7 3 c s # s clk io0 io1 io2 io 3
