32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Product Description The SST 25 series Serial Flash family features a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. SST25VF032B SPI serial flash memories are manufactured with SST’s proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain bet- ter reliability and manufacturability compared with alternate approaches. The SST25VF032B devices significantly improve performance and reliability, while lowering power consumption. The devices write (Program or Erase) with a single power supply of 2.7-3.6V for SST25VF032B. The total energy consumed is a function of the applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less current to pro- gram and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies. The SST25VF032B device is offered in 8-lead SOIC (200 mils) and 8-contact WSON packages. See Figure 2 for pin assignments. ©2015 DS20005071B 04/15 2

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Memory Organization The SST25VF032B SuperFlash memory array is organized in uniform 4 KByte erasable sectors with 32 KByte overlay blocks and 64 KByte overlay erasable blocks. Device Operation The SST25VF032B is accessed through the SPI (Serial Peripheral Interface) bus compatible protocol. The SPI bus consist of four control lines; Chip Enable (CE#) is used to select the device, and data is accessed through the Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). The SST25VF032B supports both Mode 0 (0,0) and Mode 3 (1,1) of SPI bus operations. The difference between the two modes, as shown in Figure 3, is the state of the SCK signal when the bus master is in Stand-by mode and no data is being transferred. The SCK signal is low for Mode 0 and SCK signal is high for Mode 3. For both modes, the Serial Data In (SI) is sampled at the rising edge of the SCK clock signal and the Serial Data Output (SO) is driven after the falling edge of the SCK clock signal.

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Hold Operation The HOLD# pin is used to pause a serial sequence using the SPI flash memory, but without resetting the clocking sequence. To activate the HOLD# mode, CE# must be in active low state. The HOLD# mode begins when the SCK active low state coincides with the falling edge of the HOLD# signal. The HOLD mode ends when the HOLD# signal’s rising edge coincides with the SCK active low state. If the falling edge of the HOLD# signal does not coincide with the SCK active low state, then the device enters Hold mode when the SCK next reaches the active low state. Similarly, if the rising edge of the HOLD# signal does not coincide with the SCK active low state, then the device exits from Hold mode when the SCK next reaches the active low state. See Figure 4 for Hold Condition waveform. Once the device enters Hold mode, SO will be in high-impedance state while SI and SCK can be V or IL V IH. If CE# is driven high during a Hold condition, the device returns to Standby mode. As long as HOLD# signal is low, the memory remains in the Hold condition. To resume communication with the device, HOLD# must be driven active high, and CE# must be driven active low. See Figure 4 for Hold timing. SCK HOLD# Active Hold Active Hold Active 1327 F05.0 Figure 4: Hold Condition Waveform Write Protection SST25VF032B provides software Write protection. The Write Protect pin (WP#) enables or disables the lock-down function of the status register. The Block-Protection bits (BP3, BP2, BP1, BP0, and BPL) in the status register provide Write protection to the memory array and the status register. See Table 4 for the Block-Protection description. Write Protect Pin (WP#) The Write Protect (WP#) pin enables the lock-down function of the BPL bit (bit 7) in the status register. When WP# is driven low, the execution of the Write-Status-Register (WRSR) instruction is determined by the value of the BPL bit (see Table 2). When WP# is high, the lock-down function of the BPL bit is disabled.

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Status Register The software status register provides status on whether the flash memory array is available for any Read or Write operation, whether the device is Write enabled, and the state of the Memory Write pro- tection. During an internal Erase or Program operation, the status register may be read only to deter- mine the completion of an operation in progress. Table 3 describes the function of each bit in the software status register. Table 3: Software Status Register Default at Bit Name Function Power-up Read/Write 0 BUSY 1 = Internal Write operation is in progress 0 R 0 = No internal Write operation is in progress 1 WEL 1 = Device is memory Write enabled 0 R 0 = Device is not memory Write enabled 2 BP0 Indicate current level of block write protection (See Table 4) 1 R/W 3 BP1 Indicate current level of block write protection (See Table 4) 1 R/W 4 BP2 Indicate current level of block write protection (See Table 4) 1 R/W 5 BP3 Indicate current level of block write protection (See Table 4) 0 R/W 6 AAI Auto Address Increment Programming status 0 R 1 = AAI programming mode 0 = Byte-Program mode 7 BPL 1 = BP3, BP2, BP1, BP0 are read-only bits 0 R/W 0 = BP3, BP2, BP1, BP0 are readable/writable T3.0 20005071 Busy The Busy bit determines whether there is an internal Erase or Program operation in progress. A ‘1’ for the Busy bit indicates the device is busy with an operation in progress. A ‘0’ indicates the device is ready for the next valid operation. Write Enable Latch (WEL) The Write-Enable-Latch bit indicates the status of the internal memory Write Enable Latch. If the Write-Enable-Latch bit is set to ‘1’, it indicates the device is Write enabled. If the bit is set to ‘0’ (reset), it indicates the device is not Write enabled and does not accept any memory Write (Program/Erase) commands. The Write-Enable-Latch bit is automatically reset under the following conditions: (cid:129) Power-up (cid:129) Write-Disable (WRDI) instruction completion (cid:129) Byte-Program instruction completion (cid:129) Auto Address Increment (AAI) programming is completed or reached its highest unpro- tected memory address (cid:129) Sector-Erase instruction completion (cid:129) Block-Erase instruction completion (cid:129) Chip-Erase instruction completion (cid:129) Write-Status-Register instructions ©2015 DS20005071B 04/15 7

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Auto Address Increment (AAI) The Auto Address Increment Programming-Status bit provides status on whether the device is in AAI programming mode or Byte-Program mode. The default at power up is Byte-Program mode. Block Protection (BP3,BP2, BP1, BP0) The Block-Protection (BP3, BP2, BP1, BP0) bits define the size of the memory area, as shown in Table 4, to be software protected against any memory Write (Program or Erase) operation. The Write-Status- Register (WRSR) instruction is used to program the BP3, BP2, BP1 and BP0 bits as long as WP# is high or the Block-Protect-Lock (BPL) bit is 0. Chip-Erase can only be executed if Block-Protection bits are all 0. After power-up, BP3, BP2, BP1 and BP0 are set to the defaults specified in Table 4. Block Protection Lock-Down (BPL) WP# pin driven low (V ), enables the Block-Protection-Lock-Down (BPL) bit. When BPL is set to 1, it IL prevents any further alteration of the BPL, BP3, BP2, BP1, and BP0 bits. When the WP# pin is driven high (V ), the BPL bit has no effect and its value is “Don’t Care”. After power-up, the BPL bit is reset to IH 0.

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Instructions Instructions are used to read, write (Erase and Program), and configure the SST25VF032B. The instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. The Write- Enable (WREN) instruction must be executed prior any Byte-Program, Auto Address Increment (AAI) programming, Sector-Erase, Block-Erase, Write-Status-Register, or Chip-Erase instructions. The com- plete list of instructions is provided in Table 5. All instructions are synchronized off a high to low transition of CE#. Inputs will be accepted on the ris- ing edge of SCK starting with the most significant bit. CE# must be driven low before an instruction is entered and must be driven high after the last bit of the instruction has been shifted in (except for Read, Read-ID, and Read-Status-Register instructions). Any low to high transition on CE#, before receiving the last bit of an instruction bus cycle, will terminate the instruction in progress and return the device to standby mode. Instruction commands (Op Code), addresses, and data are all input from the most significant bit (MSB) first.

To continue programming to the next sequential address location, enter the 8-bit command, ADH, followed by 2 bytes of data to be programmed. Data Byte 0 will be programmed into the initial address [A23-A1] with A0=0, Data Byte 1 will be programmed into the initial address [A23-A1] with A0 = 1. 7. The Read-Status-Register is continuous with ongoing clock cycles until terminated by a low to high transition on CE#. 8. Manufacturer’s ID is read with A0 = 0, and Device ID is read with A0 = 1. All other address bits are 00H. The Manufac- turer’s ID and device ID output stream is continuous until terminated by a low-to-high transition on CE#. Read (25 MHz) The Read instruction, 03H, supports up to 25 MHz Read. The device outputs the data starting from the specified address location. The data output stream is continuous through all addresses until termi- nated by a low to high transition on CE#. The internal address pointer will automatically increment until the highest memory address is reached. Once the highest memory address is reached, the address pointer will automatically increment to the beginning (wrap-around) of the address space. For example, once the data from address location 3FFFFFH has been read, the next output will be from address location 000000H. The Read instruction is initiated by executing an 8-bit command, 03H, followed by address bits [A - 23 A ]. CE# must remain active low for the duration of the Read cycle. See Figure 5 for the Read 0 sequence. CE# MODE 3 0 1 2 3 4 5 6 7 8 1516 2324 3132 3940 47 48 5556 6364 70 SCK MODE 0 03 ADD. ADD. ADD.

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet High-Speed-Read (80 MHz) The High-Speed-Read instruction supporting up to 80 MHz Read is initiated by executing an 8-bit com- mand, 0BH, followed by address bits [A -A ] and a dummy byte. CE# must remain active low for the 23 0 duration of the High-Speed-Read cycle. See Figure 6 for the High-Speed-Read sequence. Following a dummy cycle, the High-Speed-Read instruction outputs the data starting from the specified address location. The data output stream is continuous through all addresses until terminated by a low to high transition on CE#. The internal address pointer will automatically increment until the highest memory address is reached. Once the highest memory address is reached, the address pointer will automatically increment to the beginning (wrap-around) of the address space. For example, once the data from address location 3FFFFFH has been read, the next output will be from address location 000000H.

The selected byte must be in the erased state (FFH) when initiating a Program operation. A Byte-Program instruction applied to a protected memory area will be ignored. Prior to any Write operation, the Write-Enable (WREN) instruction must be executed. CE# must remain active low for the duration of the Byte-Program instruction. The Byte-Program instruction is initiated by executing an 8-bit command, 02H, followed by address bits [A -A ]. Following the address, the data is 23 0 input in order from MSB (bit 7) to LSB (bit 0). CE# must be driven high before the instruction is exe- cuted.

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Auto Address Increment (AAI) Word-Program The AAI program instruction allows multiple bytes of data to be programmed without re-issuing the next sequential address location. This feature decreases total programming time when multiple bytes or entire memory array is to be programmed. An AAI Word program instruction pointing to a protected memory area will be ignored. The selected address range must be in the erased state (FFH) when ini- tiating an AAI Word Program operation. While within AAI Word Programming sequence, only the fol- lowing instructions are valid: for software end-of-write detection—AAI Word (ADH), WRDI (04H), and RDSR (05H); for hardware end-of-write detection—AAI Word (ADH) and WRDI (04H). There are three options to determine the completion of each AAI Word program cycle: hardware detection by reading the Serial Output, software detection by polling the BUSY bit in the software status register, or wait T BP. Refer to“End-of-Write Detection” for details. Prior to any write operation, the Write-Enable (WREN) instruction must be executed. Initiate the AAI Word Program instruction by executing an 8-bit command, ADH, followed by address bits [A -A ]. Fol- 23 0 lowing the addresses, two bytes of data are input sequentially, each one from MSB (Bit 7) to LSB (Bit 0). The first byte of data (D0) is programmed into the initial address [A -A ] with A =0, the second 23 1 0 byte of Data (D1) is programmed into the initial address [A -A ] with A =1. CE# must be driven high 23 1 0 before executing the AAI Word Program instruction. Check the BUSY status before entering the next valid command. Once the device indicates it is no longer busy, data for the next two sequential addresses may be programmed, followed by the next two, and so on. When programming the last desired word, or the highest unprotected memory address, check the busy status using either the hardware or software (RDSR instruction) method to check for program comple- tion. Once programming is complete, use the applicable method to terminate AAI. If the device is in Software End-of-Write Detection mode, execute the Write-Disable (WRDI) instruction, 04H. If the device is in AAI Hardware End-of-Write Detection mode, execute the Write-Disable (WRDI) instruction, 04H, followed by the 8-bit DBSY command, 80H. There is no wrap mode during AAI programming once the highest unprotected memory address is reached. See Figures 10 and 11 for the AAI Word programming sequence. End-of-Write Detection There are three methods to determine completion of a program cycle during AAI Word programming: hardware detection by reading the Serial Output, software detection by polling the BUSY bit in the Soft- ware Status Register, or wait T The Hardware End-of-Write detection method is described in the BP. section below. Hardware End-of-Write Detection The Hardware End-of-Write detection method eliminates the overhead of polling the Busy bit in the Software Status Register during an AAI Word program operation. The 8-bit command, 70H, configures the Serial Output (SO) pin to indicate Flash Busy status during AAI Word programming. (see Figure 8) The 8-bit command, 70H, must be executed prior to initiating an AAI Word-Program instruction. Once an internal programming operation begins, asserting CE# will immediately drive the status of the inter- nal flash status on the SO pin. A ‘0’ indicates the device is busy and a ‘1’ indicates the device is ready for the next instruction. De-asserting CE# will return the SO pin to tri-state. While in AAI and Hardware End-of-Write detection mode, the only valid instructions are AAI Word (ADH) and WRDI (04H). To exit AAI Hardware End-of-Write detection, first execute WRDI instruction, 04H, to reset the Write- Enable-Latch bit (WEL=0) and AAI bit. Then execute the 8-bit DBSY command, 80H, to disable RY/ BY# status during the AAI command. See Figures 9 and 10. ©2015 DS20005071B 04/15 12

32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet Enable-Write-Status-Register (EWSR) The Enable-Write-Status-Register (EWSR) instruction arms the Write-Status-Register (WRSR) instruction and opens the status register for alteration. The Write-Status-Register instruction must be executed immediately after the execution of the Enable-Write-Status-Register instruction. This two- step instruction sequence of the EWSR instruction followed by the WRSR instruction works like soft- ware data protection (SDP) command structure which prevents any accidental alteration of the status register values. CE# must be driven low before the EWSR instruction is entered and must be driven high before the EWSR instruction is executed. Write-Status-Register (WRSR) The Write-Status-Register instruction writes new values to the BP3, BP2, BP1, BP0, and BPL bits of the status register. CE# must be driven low before the command sequence of the WRSR instruction is entered and driven high before the WRSR instruction is executed. See Figure 19 for EWSR or WREN and WRSR instruction sequences. Executing the Write-Status-Register instruction will be ignored when WP# is low and BPL bit is set to ‘1’. When the WP# is low, the BPL bit can only be set from ‘0’ to ‘1’ to lock-down the status register, but cannot be reset from ‘1’ to ‘0’. When WP# is high, the lock-down function of the BPL bit is disabled and the BPL, BP0, and BP1 and BP2 bits in the status register can all be changed. As long as BPL bit is set to ‘0’ or WP# pin is driven high (V ) prior to the low-to-high transition of the CE# pin at the end of IH the WRSR instruction, the bits in the status register can all be altered by the WRSR instruction. In this case, a single WRSR instruction can set the BPL bit to ‘1’ to lock down the status register as well as altering the BP0, BP1, and BP2 bits at the same time. See Table 2 for a summary description of WP# and BPL functions.
