PRODUCT DESCRIPTION
The SST34HF16x2C/D/S ComboMemory devices integrate either a 1M x16 or 2M x8 CMOS flash memory bank with either a 128K x16/256K x8, 256K x16/512 x8, or 512K x16/1024K x8 CMOS SRAM or pseudo SRAM (PSRAM) memory bank in a multi-chip package (MCP). These devices are fabricated using SST's proprietary, high-performance CMOS SuperFlash technology incorporating the split-gate cell design and thick-oxide tunneling injector to attain better reliability and manufacturability compared with alternate approaches. The SST34HF16x2C/D/S devices are ideal for applications such as cellular phones, GPS devices, PDAs, and other portable electronic devices in a low power and small form factor system. The SST34HF16x2C/D/S feature dual flash memory bank architecture allowing for concurrent operations between the two flash memory banks and the (P)SRAM. The devices can read data from either bank while an Erase or Program operation is in progress in the opposite bank. The two flash

memory banks are partitioned into 4 Mbit and 12 Mbit with top sector protection options for storing boot code, program code, configuration/parameter data and user data. The SuperFlash technology provides fixed Erase and Program times, independent of the number of Erase/Program cycles that have occurred. Therefore, the system software or hardware does not have to be modified or de-rated as is necessary with alternative flash technologies, whose Erase and Program times increase with accumulated Erase/Program cycles. The SST34HF16x2C/D/S devices offer a guaranteed endurance of 10,000 cycles. Data retention is rated at greater than 100 years. With high performance Word-Program, the flash memory banks provide a typical Word-Program time of 7 sec. The entire flash memory bank can be erased and programmed word-by-word in typically 4 seconds for the SST34HF16x2C/D/S, when using interface features such as Toggle Bit, Data# Polling, or RY/ BY# to indicate the completion of Program operation.

Advance Information protect against inadvertent flash write, the SST34HF16x2C/D/S devices contain on-chip hardware and software data protection schemes. The flash and (P)SRAM operate as two independent memory banks with respective bank enable signals. The memory bank selection is done by two bank enable signals. The (P)SRAM bank enable signals, BES1# and BES2, select the (P)SRAM bank (BES1# and BES2 are NC for SST34HF1602C). The flash memory bank enable signal, BEF#, has to be used with Software Data Protection (SDP) command sequence when controlling the Erase and Program operations in the flash memory bank. The memory banks are superimposed in the same memory address space where they share common address lines, data lines, WE# and OE# which minimize power consumption and area. Designed, manufactured, and tested for applications requiring low power and small form factor, the SST34HF16x2C/ D/S are offered in both commercial and extended temperatures and a small footprint package to meet board space constraint requirements. See Figures 3 and 4 for pin assignments.
Concurrent Read/Write Operation
Dual bank architecture of SST34HF16x2C/D/S devices allows the Concurrent Read/Write operation whereby the user can read from one bank while programming or erasing in the other bank. This operation can be used when the user needs to read system code in one bank while updating data in the other bank. See Figures 1 and 2 for dualbank memory organization.

Note: For the purposes of this table, write means to Block-, Sector, or Chip-Erase, or Word-/Byte-Program as applicable to the appropriate bank.
Device Operation
The SST34HF16x2C/D/S uses BES1#, BES2 and BEF# to control operation of either the flash or the (P)SRAM memory bank. When BEF# is low, the flash bank is activated for Read, Program or Erase operation. When BES1# is low, and BES2 is high the (P)SRAM is activated for Read and Write operation. BEF# and BES1# cannot be at low level, and BES2 cannot be at high level at the same time. If all bank enable signals are asserted, bus contention will result and the device may suffer permanent damage. All address, data, and control lines are shared by flash and (P)SRAM memory banks which minimizes power consumption and loading. The device goes into standby when BEF# and BES1# bank enables are raised to VIHC (Logic High) or when BEF# is high and BES2 is low.
Flash Read Operation
The Read operation of the SST34HF16x2C/D/S is controlled by BEF# and OE#, both have to be low for the system to obtain data from the outputs. BEF# is used for device selection. When BEF# is high, the chip is deselected and only standby power is consumed. OE# is the output control and is used to gate data from the output pins. The data bus is in high impedance state when either BEF# or OE# is high. Refer to the Read cycle timing diagram for further details (Figure 8).

Advance Information
Flash Word-/Byte-Program Operation
These devices are programmed on a word-by-word or byte-by-byte basis depending on the state of the CIOF pin. Before programming, one must ensure that the sector which is being programmed is fully erased. The Program operation is accomplished in three steps: 1. Software Data Protection is initiated using the three-byte load sequence. 2. Word address and word data are loaded. During the Word-Program operation, the addresses are latched on the falling edge of either BEF# or WE#, whichever occurs last. The data is latched on the rising edge of either BEF# or WE#, whichever occurs first. 3. The internal Program operation is initiated after the rising edge of the fourth WE# or BEF#, whichever occurs first. The Program operation, once initiated, will be completed typically within 7 s. See Figures 9 and 10 for WE# and BEF# controlled Program operation timing diagrams and Figure 22 for flowcharts. During the Program operation, the only valid reads are Data# Polling and Toggle Bit. During the internal Program operation, the host is free to perform additional tasks. Any commands issued during an internal Program operation are ignored.
Flash Chip-Erase Operation
The SST34HF16x2C/D/S provide a Chip-Erase operation, which allows the user to erase all sectors/blocks to the "1" state. This is useful when the device must be quickly erased. The Chip-Erase operation is initiated by executing a sixbyte command sequence with Chip-Erase command (10H) at address 5555H in the last byte sequence. The Erase operation begins with the rising edge of the sixth WE# or BEF#, whichever occurs first. During the Erase operation, the only valid read is Toggle Bits or Data# Polling. See Table 7 for the command sequence, Figure 13 for timing diagram, and Figure 26 for the flowchart. Any commands issued during the Chip-Erase operation are ignored. When WP# is low, any attempt to Chip-Erase will be ignored.
Flash Erase-Suspend/-Resume Operations
The Erase-Suspend operation temporarily suspends a Sector- or Block-Erase operation thus allowing data to be read from any memory location, or program data into any sector/block that is not suspended for an Erase operation. The operation is executed by issuing a one-byte command sequence with Erase-Suspend command (B0H). The device automatically enters read mode within 20 s after the Erase-Suspend command had been issued. Valid data can be read from any sector or block that is not suspended from an Erase operation. Reading at address location within erase-suspended sectors/blocks will output DQ2 toggling and DQ6 at "1". While in Erase-Suspend mode, a Word-/Byte-Program operation is allowed except for the sector or block selected for Erase-Suspend. To resume Sector-Erase or Block-Erase operation which has been suspended, the system must issue an Erase-Resume command. The operation is executed by issuing a one-byte command sequence with Erase Resume command (30H) at any address in the one-byte sequence.
Flash Sector- (Block-) Erase Operation
These devices offer both Sector-Erase and Block-Erase operations. These operations allow the system to erase the devices on a sector-by-sector (or block-by-block) basis. The sector architecture is based on a uniform sector size of 2 KWord. The Block-Erase mode is based on a uniform block size of 32 KWord. The Sector-Erase operation is initiated by executing a six-byte command sequence with a Sector-Erase command (30H) and sector address (SA) in the last bus cycle. The Block-Erase operation is initiated by executing a six-byte command sequence with Block-Erase command (50H) and block address (BA) in the last bus cycle. The sector or block address is latched on the falling edge of the sixth WE# pulse, while the command (30H or 50H) is latched on the rising edge of the sixth WE# pulse. The internal Erase operation begins after the sixth WE# pulse. Any commands issued during the Block- or SectorErase operation are ignored except Erase-Suspend and Erase-Resume. See Figures 14 and 15 for timing waveforms.

Advance Information
Flash Write Operation Status Detection
The SST34HF16x2C/D/S provide one hardware and two software means to detect the completion of a Write (Program or Erase) cycle, in order to optimize the system Write cycle time. The hardware detection uses the Ready/Busy# (RY/BY#) pin. The software detection includes two status bits: Data# Polling (DQ7) and Toggle Bit (DQ6). The End-of-Write detection mode is enabled after the rising edge of WE#, which initiates the internal Program or Erase operation. The actual completion of the nonvolatile write is asynchronous with the system; therefore, either a Ready/Busy# (RY/ BY#), Data# Polling (DQ7) or Toggle Bit (DQ6) read may be simultaneous with the completion of the Write cycle. If this occurs, the system may possibly get an erroneous result, i.e., valid data may appear to conflict with either DQ7 or DQ6. In order to prevent spurious rejection, if an erroneous result occurs, the software routine should include a loop to read the accessed location an additional two (2) times. If both reads are valid, then the device has completed the Write cycle, otherwise the rejection is valid.
Flash Data# Polling (DQ7)
When the devices are in an internal Program operation, any attempt to read DQ7 will produce the complement of the true data. Once the Program operation is completed, DQ7 will produce true data. During internal Erase operation, any attempt to read DQ7 will produce a `0'. Once the internal Erase operation is completed, DQ7 will produce a `1'. The Data# Polling is valid after the rising edge of fourth WE# (or BEF#) pulse for Program operation. For Sector-, Block-, or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or BEF#) pulse. See Figure 11 for Data# Polling (DQ7) timing diagram and Figure 23 for a flowchart.
Toggle Bits (DQ6 and DQ2)
During the internal Program or Erase operation, any consecutive attempts to read DQ6 will produce alternating "1"s and "0"s, i.e., toggling between 1 and 0. When the internal Program or Erase operation is completed, the DQ6 bit will stop toggling. The device is then ready for the next operation. The toggle bit is valid after the rising edge of the fourth WE# (or BEF#) pulse for Program operations. For Sector-, Block-, or Chip-Erase, the toggle bit (DQ6) is valid after the rising edge of sixth WE# (or BEF#) pulse. DQ6 will be set to "1" if a Read operation is attempted on an Erase-suspended Sector/Block. If Program operation is initiated in a sector/block not selected in Erase-Suspend mode, DQ6 will toggle. An additional Toggle Bit is available on DQ2, which can be used in conjunction with DQ6 to check whether a particular sector is being actively erased or erase-suspended. Table 1 shows detailed status bit information. The Toggle Bit (DQ2) is valid after the rising edge of the last WE# (or BEF#) pulse of a Write operation. See Figure 12 for Toggle Bit timing diagram and Figure 23 for a flowchart. TABLE 1: WRITE OPERATION STATUS
Status Normal Operation Standard Program Standard Erase EraseSuspend Mode Read From Erase Suspended Sector/Block Read From Non-Erase Suspended Sector/Block Program DQ7 DQ7# 0 1 DQ6 Toggle Toggle 1 DQ2 No Toggle Toggle Toggle RY/BY# 0 0 1
Ready/Busy# (RY/BY#)
The SST34HF16x2C/D/S include a Ready/Busy# (RY/ BY#) output signal. RY/BY# is an open drain output pin that indicates whether an Erase or Program operation is in progress. Since RY/BY# is an open drain output, it allows several devices to be tied in parallel to VDD via an external pull-up resistor. After the rising edge of the final WE# pulse in the command sequence, the RY/BY# status is valid. When RY/BY# is actively pulled low, it indicates that an Erase or Program operation is in progress. When RY/BY# is high (Ready), the devices may be read or left in standby mode.
Byte/Word (CIOF)
The device includes a CIOF pin to control whether the device data I/O pins operate x8 or x16. If the CIOF pin is at logic "1" (VIH) the device is in x16 data configuration: all data I/0 pins DQ0-DQ15 are active and controlled by BEF# and OE#. If the CIOF pin is at logic "0", the device is in x8 data configuration: only data I/O pins DQ0-DQ7 are active and controlled by BEF# and OE#. The remaining data pins DQ8DQ14 are at Hi-Z, while pin DQ15 is used as the address input A-1 for the Least Significant Bit of the address bus.

Advance Information
Data Protection
The SST34HF16x2C/D/S provide both hardware and software features to protect nonvolatile data from inadvertent writes.
Software Data Protection (SDP)
The SST34HF16x2C/D/S provide the JEDEC standard Software Data Protection scheme for all data alteration operations, i.e., Program and Erase. Any Program operation requires the inclusion of the three-byte sequence. The three-byte load sequence is used to initiate the Program operation, providing optimal protection from inadvertent Write operations, e.g., during the system power-up or power-down. Any Erase operation requires the inclusion of six-byte sequence. The SST34HF16x2C/D/S are shipped with the Software Data Protection permanently enabled. See Table 7 for the specific software command codes. During SDP command sequence, invalid commands will abort the device to Read mode within TRC. The contents of DQ15DQ8 are "Don't Care" during any SDP command sequence.
Hardware Data Protection
Noise/Glitch Protection: A WE# or BEF# pulse of less than 5 ns will not initiate a Write cycle. VDD Power Up/Down Detection: The Write operation is inhibited when VDD is less than 1.5V. Write Inhibit Mode: Forcing OE# low, BEF# high, or WE# high will inhibit the Write operation. This prevents inadvertent writes during power-up or power-down.
Hardware Block Protection
The SST34HF16x2C/D/S provide a hardware block protection which protects the outermost 8 KWord in Bank 1. The block is protected when WP# is held low. See Figures 1 and 2 for Block-Protection location. A user can disable block protection by driving WP# high thus allowing erase or program of data into the protected sectors. WP# must be held high prior to issuing the write command and remain stable until after the entire Write operation has completed.
Security ID
The SST34HF16x2C/D/S devices offer a 256-bit Security ID space. The Secure ID space is divided into two 128-bit segments--one factory programmed segment and one user programmed segment. The first segment is programmed and locked at SST with a unique, 128-bit number. The user segment is left un-programmed for the customer to program as desired. To program the user segment of the Security ID, the user must use the Security ID Word-Program command. End-of-Write status is checked by reading the toggle bits. Data# Polling is not used for Security ID End-of-Write detection. Once programming is complete, the Sec ID should be locked using the User-SecID-Program-Lock-Out. This disables any future corruption of this space. Note that regardless of whether or not the Sec ID is locked, neither Sec ID segment can be erased. The Secure ID space can be queried by executing a threebyte command sequence with Query-Sec-ID command (88H) at address 5555H in the last byte sequence. To exit this mode, the Exit-Sec-ID command should be executed. Refer to Table 7 for more details.
Hardware Reset (RST#)
The RST# pin provides a hardware method of resetting the device to read array data. When the RST# pin is held low for at least TRP, any in-progress operation will terminate and return to Read mode (see Figure 19). When no internal Program/Erase operation is in progress, a minimum period of TRHR is required after RST# is driven high before a valid Read can take place (see Figure 18). The Erase operation that has been interrupted needs to be reinitiated after the device resumes normal operation mode to ensure data integrity. See Figures 18 and 19 for timing diagrams.

Advance Information
Product Identification
The Product Identification mode identifies the device as the SST34HF16x2C/D/S and manufacturer as SST. This mode may be accessed by software operations only. The hardware device ID Read operation, which is typically used by programmers cannot be used on this device because of the shared lines between flash and (P)SRAM in the multichip package. Therefore, application of high voltage to pin A9 may damage this device. Users may use the software Product Identification operation to identify the part (i.e., using the device ID) when using multiple manufacturers in the same socket. For details, see Tables 4 and 7 for software operation, Figure 16 for the Software ID Entry and Read timing diagram and Figure 24 for the ID Entry command sequence flowchart.

T2.0 1256
(P)SRAM Operation
With BES1# low, BES2 and BEF# high, the SST34HF16x2C/D/S operate as either 128K x16, 256K x16, or 512K x16 CMOS (P)SRAM, with fully static operation requiring no external clocks or timing strobes. The SST34HF16x2C/D/S (P)SRAM is mapped into the first 512 KWord address space. When BES1#, BEF# are high and BES2 is low, all memory banks are deselected and the device enters standby. Read and Write cycle times are equal. The control signals UBS# and LBS# provide access to the upper data byte and lower data byte (UBS# and LBS# signals are NC for SST3416x2S parts). See Table 4 for x16 (P)SRAM Read and Write data byte control modes of operation. See Table 5 for x8 SRAM Read and Write data byte control modes of operation.
(P)SRAM Read
DATA 00BFH
BK0000H
Note: BK = Bank Address (A19-A18)
The (P)SRAM Read operation of the SST34HF16x2C/D/S is controlled by OE# and BES1#, both have to be low with WE# and BES2 high for the system to obtain data from the outputs. BES1# and BES2 are used for (P)SRAM bank selection. OE# is the output control and is used to gate data from the output pins. The data bus is in high impedance state when OE# is high. Refer to the Read cycle timing diagram, Figure 5, for further details.
Product Identification Mode Exit
In order to return to the standard Read mode, the Software Product Identification mode must be exited. Exit is accomplished by issuing the Software ID Exit command sequence, which returns the device to the Read mode. This command may also be used to reset the device to the Read mode after any inadvertent transient condition that apparently causes the device to behave abnormally, e.g., not read correctly. Please note that the Software ID Exit command is ignored during an internal Program or Erase operation. See Table 7 for software command codes, Figure 17 for timing waveform and Figure 24 for a flowchart.
(P)SRAM Write
The (P)SRAM Write operation of the SST34HF16x2C/D/S is controlled by WE# and BES1#, both have to be low, BES2 must be high for the system to write to the (P)SRAM. During the Word-Write operation, the addresses and data are referenced to the rising edge of either BES1#, WE#, or the falling edge of BES2 whichever occurs first. The write time is measured from the last falling edge of BES#1 or WE# or the rising edge of BES2 to the first rising edge of BES1#, or WE# or the falling edge of BES2. Refer to the Write cycle timing diagrams, Figures 6 and 7, for further details.
