1 Mbit SPI Serial Flash

SST25VF010A

SST's serial flash family features a four-wire, SPI-compatible interface that allows

for a low pin-count package occupying less board space and ultimately lowering

total system costs. SST25VF010A SPI serial flash memory is manufactured with

SST proprietary, high performance CMOS SuperFlash Technology. The split-gate

cell design and thick-oxide tunneling injector attain better reliability and manufac-

turability compared with alternate approaches.

Device Operation The SST25VF010A is accessed through the SPI (Serial Peripheral Interface) bus compatible protocol.

1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Hold Operation HOLD# pin is used to pause a serial sequence underway with the SPI flash memory 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.

1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company 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 protection. During an internal Erase or Program operation, the status register may be read only to determine the completion of an operation in progress.
PAGE 8
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Block Protection (BP1, BP0) The Block-Protection (BP1, BP0) bits define the size of the memory area, as defined in Table 5, to be software protected against any memory Write (Program or Erase) operations. The Write-Status-Register (WRSR) instruction is used to program the BP1 and BP0 bits as long as WP# is high or the BlockProtect-Lock (BPL) bit is 0. Chip-Erase can only be executed if Block-Protection bits are both 0.

1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Instructions Instructions are used to Read, Write (Erase and Program), and configure the SST25VF010A. The instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. Prior to executing any Byte-Program, Auto Address Increment (AAI) programming, Sector-Erase, Block-Erase, or Chip-Erase instructions, the Write-Enable (WREN) instruction must be executed first.
PAGE 10
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet 6. Prior to any Byte-Program, AAI-Program, Sector-Erase, Block-Erase, or Chip-Erase operation, the Write-Enable (WREN) instruction must be executed. 7. Block addresses for: use AMS-A15, remaining addresses can be VIL or VIH 8. To continue programming to the next sequential address location, enter the 8-bit command, AFH, followed by the data to be programmed. 9.
PAGE 11
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet High-Speed-Read (33 MHz) The High-Speed-Read instruction supporting up to 33 MHz is initiated by executing an 8-bit command, 0BH, followed by address bits [A23-A0] and a dummy byte. CE# must remain active low for the duration of the High-Speed-Read cycle. See Figure 5 for the High-Speed-Read sequence.
PAGE 12
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Byte-Program The Byte-Program instruction programs the bits in the selected byte to the desired data. 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.
PAGE 13
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Auto Address Increment (AAI) 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 the entire memory array is to be programmed. An AAI program instruction pointing to a protected memory area will be ignored.
PAGE 14
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Sector-Erase The Sector-Erase instruction clears all bits in the selected 4 KByte sector to FFH. A Sector-Erase instruction applied to a protected memory area will be ignored. Prior to any Write operation, the WriteEnable (WREN) instruction must be executed. CE# must remain active low for the duration of the any command sequence.
PAGE 15
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Chip-Erase The Chip-Erase instruction clears all bits in the device to FFH. A Chip-Erase instruction will be ignored if any of the memory area is protected. Prior to any Write operation, the Write-Enable (WREN) instruction must be executed. CE# must remain active low for the duration of the Chip-Erase instruction sequence. The Chip-Erase instruction is initiated by executing an 8-bit command, 60H or C7H.
PAGE 16
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Write-Enable (WREN) The Write-Enable (WREN) instruction sets the Write-Enable-Latch bit to 1 allowing Write operations to occur. The WREN instruction must be executed prior to any Write (Program/Erase) operation. CE# must be driven high before the WREN instruction is executed. CE# MODE 3 SCK 0 1 2 3 4 5 6 7 MODE 0 06 SI MSB HIGH IMPEDANCE SO 1265 F12.
PAGE 17
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Write-Status-Register (WRSR) The Write-Status-Register instruction works in conjunction with the Enable-Write-Status-Register (EWSR) instruction to write new values to the BP1, BP0, and BPL bits of the status register. The WriteStatus-Register instruction must be executed immediately after the execution of the Enable-Write-Status-Register instruction (very next instruction bus cycle).
PAGE 18
1 Mbit SPI Serial Flash SST25VF010A A Microchip Technology Company Data Sheet Read-ID The Read-ID instruction identifies the device as SST25VF010A and manufacturer as SST. The device information can be read from executing an 8-bit command, 90H or ABH, followed by address bits [A23A0]. Following the Read-ID instruction, the manufacturer’s ID is located in address 00000H and the device ID is located in address 00001H.
