TMP19A64F20AXBG tmp19a64(rev1.1)-3-1 3. flash memory operation this section describes the hardware configuration and operation of the flash memory. the feature of this device is that the internal rom of tmp19a 64c1dxbg is replaced by an internal flash memory. other configurations and functions of the device remain the same as with tmp19a64c1dxbg. please refer to the tmp19a64c1dxbg data sheet for functions not described in this section. 3.1 flash memory 3.1.1 features 1) memory capacity the TMP19A64F20AXBG device contains two 8m bits (1mb) of flash memory capacity. the memory area consists of 4 independent memory blocks (128 kb 16) to enable independent write access to each block. when the cpu is to access th e internal flash memory, 32-bit data bus width is used. 2) write/erase write unit: 1 page (128 words) 4k erase unit: selectable from 128 kb, 512 kb, and 1 mb protection unit: selectable in 512 kb blocks protection erasure unit: selectable in 1 mb blocks 3) write/erase time write time: 8 sec/2 chip (typ) 2 msec/128 word (typ.) erase time: 1.6 sec /2 chip (typ) 100 msec/128 kbyte (typ.) protection bit erase time: 100 msec/2 bit (typ) (note) the above values are theoretical va lues not including data transfer time. the write time per chip depends on the write method to be used by the user. 4) programming method two modes are available, i.e., the onboard programming mode to allow programming on the user's board and the writer mode to program the device using an eprom writer. ? onboard programming mode 1) user boot mode the user's original rewriting method can be supported. 2) single boot mode the rewriting method to use serial data transfer (toshiba's unique method) can be supported. ? writer mode use of a general purpose eprom writer is supported. 5) rewriting method the flash memory included in this device is generally compliant with the applicable jedec standards except for some specific functions. therefore, if the user is currently using an external flash memory device, it is easy to implement the functions into this device. furthermore, the user is not required to build his/her own programs to realize complicated write and erase functions because such functions are automatically performe d using the circuits al ready built-in the flash memory chip. this device is also implemented with a read-sec urity function to inhibit reading flash memory data from any external writer device. on the other hand, rewrite protection is available only through command-based software programming; any hardware setting method to apply +12vdc is not supported. the above described security fu nction is automatically enabled when all the four area are configured for protection. when the user removes protection, the internal data is automatically erased before the protection is actually removed.

TMP19A64F20AXBG tmp19a64(rev1.1)-3-3 3.2 operation mode this device has four operation modes including the mode not to use the internal flash memory. table 3.2.1.1 operation modes operation mode operation details single chip mode after reset is cleared, it starts up from the internal flash memory. normal mode in this operation mode, two diffe rent modes, i.e., the mode to execute user application programs and the mode to rewrite the flash memory onboard the user?s card, are defined. the former is referred to as "normal mode" an d the latter "user boot mode." user boot mode the user can uniquely configur e the system to switch be tween these two modes. for example, the user can freely design the system such that the normal mode is selected when the port "00" is set to "1" and the user boot m ode is selected when it is set to "0." the user should prepare a routine as part of the application program to make the decision on the selection of the modes. single boot mode after reset is cleared, it starts up from the inte rnal boot rom (mask rom) . in the boot rom, an algorithm to enable flash memory rewriting on the us er?s set through the serial port of this device is programmed. by connecting to an external host computer through the seri al port, the internal flash memory can be programmed by transferring data in accordance with predefined protocols. writer mode this mode allows use of a ge neral purpose eprom writer to rewrite the internal flash memory. please use a special program adaptor and an eprom writer that are recommended for use. among the flash memory operation modes listed in the above table, the user boot mode, single boot mode, and writer mode are programmable modes. these two modes, the user boot mode and the single boot mode, are referred to as "onboard programming" modes where onboard rewriting of internal flash memory can be made on the user's card.
TMP19A64F20AXBG tmp19a64(rev1.1)-3-4 either the single chip, single boot, or writer operation m ode can be selected by externally setting the levels of the bw0, bw1, and boot input pins while the device is in the reset state. except for the case of the writer mode , the cpu starts operation in the selected operation mode when the reset condition is removed after the pin levels are set. the writer mode is used with reset set to "0". be sure not to change the levels during operation once the mode is selected. the mode setting method and the mode transition diagram are shown below: table 3.2.1.2 operation mode setting input pin operation mode reset bw0 bw1 boot (1) single chip mode 0 1 1 1 1 (2) single boot mode 0 1 1 1 0 (3) writer mode *1 *1 *1 *1 *1: don't care (no explanation is given in this section regarding condition settings.) fig. 3.2.1.3 mode transition diagram 3.2.1 reset operation to reset the device, ensure that the power supply voltage is within the operating voltage range, that the internal oscillator has been stabilized, and that the reset input is held at "0" for a minimum duration of 12 system clocks (1.8 s with 54 mhz operation; the "1/8" cloc k gear mode is applied after reset). (note 1) regarding power-on reset of devices with internal flash memory; for devices with internal flash memory, it is necessary to apply "0" to the reset inputs upon power on for a minimum duration of 60 microseconds regardless of the operating frequency. during this period, each protection bit, to be described later, is locked in the state it is written regardless of the state it ought to be. the original values of protection bits can be checked by reading the register flcs after the power on reset operation is normally terminated.

TMP19A64F20AXBG tmp19a64(rev1.1)-3-7 3.3 on-board programming of fl ash memory (rewrite/erase) in on-board programming, the cpu is to execute softwa re commands for rewriting or erasing the flash memory. the rewrite/erase control program should be prepared by the user beforehand. because the flash memory content cannot be read while it is being written or eras ed, it is necessary to run the rewrite/erase program from the internal ram or from an external memory device after shifting to the user boot mode. in this section, flash memory addresses are represented in virtual addresses unless otherwise noted. 3.4 flash memory except for some functions, writing and erasing flash memo ry data are in accordance with the standard jedec commands. in writing or erasing, use the sw command of the cpu to enter commands to the flash memory. once the command is entered, the actual write or er ase operation is automatically performed internally. table 3.4.1.1 flash memory functions major functions description automatic page program writes data au tomatically (in 128 word blocks). automatic chip erase automatically erases the flash memory area one chip at a time (1 mb at a time). automatic block erase erases a selected block automatically (128 kb at a time). write protect the write or erase function can be individually in hibited for each area (of 512 kb). when all areas are set for protection, the security function is automatically enabled. security function a security function is implem ented to inhibit reading from the flash memory when the device is in the writer mode. by setting protection to all the four areas, the security function is enabled. in order to disable the security f unction, it is necessary to cancel write protection when the entire flash memory is automatically erased. note that addressing of operation commands is differ ent from the case of standard commands due to the specific interface arrangements with the cpu as detailed operation of the user boot mode and ram transfer mode is described later. also note that the flash memory is wr itten in 32-bit blocks. so, 32-bit (word) data transfer commands must be used in writing the flash memory.

TMP19A64F20AXBG tmp19a64(rev1.1)-3-9 (2) basic operation generally speaking, this flash memory device has the following two operation modes: ? the mode to read memory data (read mode) ? the mode to automatically erase or rewrite memory data (automatic operation) transition to the automatic mode is made by executing a command sequence while it is in the memory read mode. in the automatic operation mode, flash memory data cannot be read and any commands stored in the flash memory cannot be executed. during automatic operation, be sure not to cause any exceptions other than debug exceptions and reset wh ile a dsu probe is connected. any interrupt or exception generation cannot set the device to the read mode except when a hardware reset is generated. 1) read when data is to be read, the flash memory must be set to the read mode. the flash memory will be set to the read mode immediately after power is applied, when cpu reset is removed, or when an automatic operation is normally terminated. in order to return to the read mode from other modes or after an automatic operation has been abnormally terminated, either the read/reset command (a software command to be described later) or a hardware reset is used. the device must also be in the read mode when any command written on the flash memory is to be executed. ? read/reset command and read command (software reset) when an automatic operation is abnormally terminated, the flash memory cannot return to the read mode by itself (when flcs = 0, data read from the flash memory is undefined.) in this case, the read/reset command can be used to return the flash memory to the read mode. also, when a command that has not been completely written has to be canceled, the read/reset command must be used to return to the read mode. the read command is used to return to the read mode after executing the sw command to write the data "0x0000_00f0" to two arbitrary addresses 0x001x_xxxx and 0x000x_xxxx of the flash memory. ? with the read/reset command, the device is returned to the read mode after completing the third bus write cycle. 2) command write this flash memory uses the command control method. commands are ex ecuted by executing a command sequence to the flash memory. the flash memory executes automatic operation commands according to the address and data combinations applied (refer to command sequence). if it is desired to cancel a command write operatio n already in progress or when any incorrect command sequence has been entered, the read/reset command is to be executed. then, the flash memory will terminate the command execution and return to the read mode. also, when issuing a command, the address [20:19] must be fixed to either "1" or "0" in order to enable a decision to sel ect either chip 0 or 1. while commands are generally comprised of several bus cycles, the operation to apply the sw command to the flash memory is called "bus write cycle." the bus write cycles are to be in a specific sequential order and the flash memory will perform an automatic operation when the sequence of the bus write cycle data and addr ess of a command write operation is in accordance with a predefined specific se quence. if any bus write cycl e does not follow a predefined command write sequence, the flash memory will terminate the command execution and return to the read mode. the address [31:21] in each bus write cycle should be the virtual address [31:21] of command execution. it will be explained later for the address bits [20:8].
TMP19A64F20AXBG tmp19a64(rev1.1)-3-10 (note 1) command sequences are executed from outside the flash memory area. (note 2) the interval between bus write cycles for this device must be 15 system clock cycles or longer. the command sequencer in the flash memory device requires a certain time period to recognize a bus write cycle. if more than one bus write cycles are executed within this time period, normal operation cannot be expected. for adjusting the applicable bus write cycle interval using a software timer to be operated at the operating frequency, use the section 10) "id-read" to check for the appropriateness. (note 3) between the bus write cycles, never use any load command (such as lw, lh, or lb) to the flash memory or perform a dma transmission by specifying the flash area as the source address. also, don't execute a jump comma nd to the flash memory. while a command sequence is being executed, don't generate any interrupt such as maskable interrupts (except debug exceptions when a dsu probe is connected). if such an operation is made, it can result in an unexpected read access to the flash memory and the command sequencer may not be able to correctly recognize the command. while it could cause an abnormal termination of the command sequence, it is also possible that the written command is incorrectly recognized. (note 4) the sync command must be executed i mmediately after the sw command for each bus write cycle. (note 5) for the command sequencer to recognize a command, the device must be in the read mode prior to executing the command. be sure to check before the first bus write cycle that the flcs[0] rdy/bsy bit is set to "1." it is recommended to subsequently execute a read command. (note 6) upon issuing a command, if any address or data is incorrec tly written, be sure to perform a system reset operation or issue a reset command (for chip 0 and chip 1 ) to return to the read mode again. 3) reset hardware reset the flash memory has a reset input as the memory block and it is connected to the cpu reset signal. therefore, when the reset inpu t pin of this device is set to v il or when the cpu is reset due to any overflow of the watch dog timer, the flash memory will return to the read mode terminating any automatic operation that may be in progress. the cpu reset is also used in returning to the read mode when an automatic operation is abnormally terminated or when any mode set by a command is to be canceled. it should also be noted that applying a hardware reset during an automatic operation can result in incorrect rewriting of data. in such a case, be sure to perform the rewriting again. refer to section 3.1 "reset operation" for cpu reset operations. after a given reset input, the cpu will read the reset vector data from the flash memory and starts operation after the reset is removed. 4) automatic page programming writing to a flash memory device is to make "1" data cells to "0" data cells. any "0" data cell cannot be changed to a "1" data cell. for making "0" data cells to "1" data cells, it is necessary to perform an erase operation. the automatic page programming function of this device writes data in 128 word blocks. a 128 word block is defined by a same [31:9] address and it starts from the address [8:0] = 0 and ends at the address [8:0] = 0x1ff. this programming unit is hereafter referred to as a "page."
TMP19A64F20AXBG tmp19a64(rev1.1)-3-11 writing to data cells is automatically performed by an internal sequencer and no external control by the cpu is required. the state of automati c page programming (whether it is in writing operation or not) can be checked by the flcs register. also, any new command sequence is not accepted while it is in the automatic page programming mode. if it is desired to interrupt the automatic page programming, use the hardware reset function. if the operation is stopped by a hardwa re reset operation, it is necessary to once erase the page and then perform the automatic page programming again because writing to the page has not been normally terminated. the automatic page programming operation is allowed only once for a page already erased. no programming can be performed twice or more times irrespective of the data cell value whether it is "1" or "0." note that rewriting to a page that has been once written requires execution of the automatic block erase or automatic chip erase command before executing the automatic page programming command again. note that an attempt to rewrite a page two or more times without erasing the content can cause damages to the device. no automatic verify operation is performed internally to the device. so, be sure to read the data programmed to confirm that it has been correctly written. the automatic page programming operation starts when the fourth bus write cycle of the command cycle is completed. on and after th e fifth bus write cycle, data will be written sequentially starting from the next address of the address specified in the fourth bus write cycle (in the fourth bus write cycle, the page top addr ess will be command written) (32 bits of data is input at a time). be sure to use the sw command in writing commands on and after the fourth bus cycle. in this, any sw command shall not be placed across word boundary. on and after the fifth bus write cycle, data is command written to the same page area. even if it is desired to write the page only partially, it is required to perform the automatic page programming for the entire page. in this case, the address input for the fourth bus write cycle shall be set to the top address of the page. be sure to perform command write operation w ith the input data set to "1" for the data cells not to be set to "0." for example, if the top address of a page is not to be written, set the input data of the fourth bus write cycle to 0x ffffffff to command write the data. once the fourth bus cycle is executed, it is in the automatic programming operation. this condition can be checked by monitoring the re gister bit flcs . any new command sequence is not accepted while it is in automatic page programming mode. if it is desired to stop operation, use the hardware reset function. be careful in doing so because data cannot be written normally if the operation is interrupted. when a single page has been command written normally terminating the automatic page writing process, the flcs bit is set to "1" and it returns to the read mode. when multiple pages are to be written, it is necessary to execute the page programming command for each page because the number of pa ges to be written by a single execution of the automatic page program command is limited to only one page. it is not allowed for automatic page programming to process input data across pages. data cannot be written to a protected block. when automatic programming is finished, it automatically returns to the read mode. this condition can be checked by monitoring flcs . if automatic programming has failed, the flash memory is locked in the mode and will not return to the read mode. for returning to the read mode, it is necessary to use the reset command or hardware reset to reset the flash memo ry or the device. in this case, while writing to the address has failed, it is recommended not to use the device or not to use the block that includes the failed address. note: software reset becomes ineffective in bus write cycles on and after the fourth bus write cycle of the automatic page programming command.
TMP19A64F20AXBG tmp19a64(rev1.1)-3-12 5) automatic chip erase (1mb at a time) the automatic chip erase operati on starts when the sixth bus write cycle of the command cycle is completed. this condition can be checked by monitoring flcs . while no automatic verify operation is performed internally to the device, be sure to read the data to confirm that data has been correctly erased. any new command sequence is not accepted while it is in an automatic chip erase operation. if it is desired to stop op eration, use the hardware reset function. if the operation is forced to stop, it is necessary to perform the automatic chip erase operation again because the data erasing operation has not been normally terminated. also, any protected blocks cannot be erased. if all the blocks are protected, the automatic chip erase operation will not be performed and it return s to the read mode after completing the sixth bus read cycle of the command sequence. when an automatic chip erase operation is normally terminated, it automatically returns to the read mode. if an automatic chip erase operation has failed, the flash memory is locked in the mode and will not return to the read mode. for returning to the read mode, it is necessary to use the reset command or hardware reset to reset the flash memory or the device. in this case, the failed block cannot be detected. it is recommended not to use the device anymore or to identify the failed block by using the block erase function for not to use the identified block anymore. 6) automatic block erase (128 kb at a time) the automatic block erase operation starts when the sixth bus write cycle of the command cycle is completed. this status of the automatic block erase operation can be checked by monitoring flcs . while no automatic verify operation is performed internally to the device, be sure to read the data to confirm that data has been correctly erased. any new command sequence is not accepted while it is in an automatic block erase operation. if it is desired to stop operation, use the hardware reset function. in this case, it is necessary to perform the automatic block erase operation again because the data erasing op eration has not been normally terminated. note that any block in the protected area is not erased. it returns to the read mode upon completing the last bus cycle of the command sequence. if an automatic block erase operation has failed, the flash memory is locked in the mode and will not return to the read mode. in this case, use the reset command or hardware reset to reset the flash memory or the device. note: commands can be accepted only by chip 0. even if automatic protection bit programming or erasure is commanded to chip 1, it will not result in any setting or clearing of the protection. 7) automatic programming of protection bits (for each 512 kb block) this device is implemented with four protection bits. the protection bits can be individually set in the automatic programming. the applicable protection bit is specified in the seventh bus write cycle. by automatically programming the protection bits, write and/or erase functions can be inhibited individually for each protection area. the protection status of each area can be checked by flcs to be described later. any new command sequence is not accepted while automatic programming is in progress to program the protection bits. if it is desired to stop the programming operation, use the hardware rese t function. in this case, it is necessary to perform the programming operation again because the protection bits may not have been correctly programmed. if all the protection bits have been programmed, the flash memory cannot be read
TMP19A64F20AXBG tmp19a64(rev1.1)-3-13 from any area outside the flash memory such as the internal ram. in this condition, the flcs register is set to "0xf" (secure state). after this, no command writing can be performed. note: commands can be accepted only by chip 0. even if automatic protection bit programming or erasure is commanded to chip 1, it will not result in any setting or clearing of the protection. note: software reset is ineffective in the seventh bus write cycle of the automatic protection bit programming command. the flcs bit turns to "0" after entering the seventh bus write cycle. 8) automatic erasing of protection bits different results will be obtained when the automatic protection bit erase command is executed depending on the status of the protection bits. it depends on the status of flcs before the command execution whether it is set to "0 x f" or to any other values. be sure to check the value of flcs before executing the automatic protection bit erase command. ? when flcs is set to "0 x f" (all the protection bits are programmed): when the automatic protection bit erase comma nd is command written, the flash memory is automatically initialized within the device. when the seventh bus write cycle is completed, the entire area of the flash memory data cells is erased and then all the protection bits are erased. this operation can be checked by monitoring flcs . if the automatic operation to erase protection bits is normally terminated, flcs will be set to "0x0." while no automatic verify operation is performed internally to the device, be sure to read the data to confirm that it has been correctly erased. for returning to the read mode while the automatic operation after the seventh bus cycle is in progress , it is necessary to use the hardware reset to reset the flash memory or the device. if this is done, it is necessary to check the status of protection bits by flcs after retuni ng to the read mode and perform either the automatic protection bit erase, automatic chip er ase, or automatic block erase operation, as appropriate. ? when flcsis other than "0 x f" (not all the protection bits are programmed): the protection condition can be canceled by the au tomatic protection bit erase operation. with this device, protection bits can be erased handling two bits at a time. the ta rget bits are specified in the seventh bus write cycle and when the command is completed, the device is in a condition the two bits are erased. the protection status of each block can be checked by flcs to be described later. this status of the programming operation for automatic protection bits can be checked by monitoring flcs . when the automatic operation to erase protection bits is norma lly terminated, the two protection bits of flcs selected for erasure are set to "0." in any case, any new command sequence is not accept ed while it is in an automatic operation to erase option bits. if it is desired to stop the operation, use the hardware reset function. when the automatic operation to erase option bits is normally terminated, it returns to the read mode.

(note) be sure to confirm the ready status whenever a command is to be issued. issuing a command while the device is busy may result in a situation where further command inputs are rejected in addition to the fact that the command cannot be transferred correctly. in such a case, restore the system by using system reset or a reset command. bit 1: programming bit this bit notifies the flash interface that a co mmand is to be issued to the flash memory. be sure to set this bit to "1" whenever a command is to be issued to the internal flash memory. also, when all commands have been issued, set this bit to "0" after confirming that the bit is set to "1." bit 2: rom type identification bit this bit is read after reset to identify wh ether the rom is a flash rom or a mask rom. flash rom: "0" mask rom: "1" bits [7:4]: protection bits (x: can be set to any combination of areas) each of the protection bits (4 bits) represents the protection status of the corresponding area. when a bit is set to "1," it indicates that the ar ea corresponding to the bit is protecte d. when the area is protected, data cannot be writt en into it.
TMP19A64F20AXBG tmp19a64(rev1.1)-3-15 10) id-read using the id-read command, you can obtain the type and other information on the flash memory contained in the device. the data to be loaded will be different depending on the write address to the flash [15:14] of the fourth and subsequent bus write cycles (any input data other than 0xf0 can be used). on and after the fourth bus write cycle, when an lw command (to read an arbitrary flash memory area) is executed after an sw co mmand, the id value will be loaded (execute a sync command immediately after the lw command) . once the fourth bus write cycle of an id- read command has passed, the device will not automatically return to the read mode. in this condition, the set of the fourth bus write cycle and lw/sync commands can be repetitively executed. for returning to the read mode, rese t the system or use the read or read/reset command. the id-read command can be used when it is nece ssary for an application to identify whether the device in the product has an internal flash memory or an internal rom. th is is effective because a mask rom doesn't have a command sequencer so it interprets any id-read command written as simply a pair of sw and lw commands applied to the mask rom. if an id-read command is to be executed on a device with an internal ma sk rom, it is necessary to select an address at which the return value to a normal lw command is different from the id-read execution result (id) from a device with an internal flash memory, also taking into account any applicable security conditions. note: setting is required when a command is to be issued to chip 0 or chip 1. refer to (4) list of command sequences.

(note 1) always set "0" to the address bits [1:0] in the entire bus cycle. (setting values to bits [7:2] are undefined.) (note 2) bus cycles are "bus write cycles" except for the second bus cycle of the read command, the fourth bus cycle of the read/reset command, and the fifth bus cycle of the id-read command. bus write cycles are executed by sw commands. use "data" in the table for the rt register [7:0] of sw commands. the address [31:16] in each bus write cycle should be the target flash memory address [31:16] of the command sequence. use "addr." in the table for the address [15:0]. (note 3) in executing the bus write cycles, the interval between each bus write cycle shall be 15 system clocks or more. (note 4) the "sync command" must be executed immediately after completing each bus write cycle.
