... SST's 25 series Serial Flash family features a four-wire, SPI-compatible inter- face that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. The SST25VF040B devices are enhanced with improved operating frequency which lowers power consump- tion. SST25VF040B SPI serial flash memories are manufactured with SST's proprietary, high-performance CMOS SuperFlash technology ...

... Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). The SST25VF040B 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 ...

... Figure 4: Hold Condition Waveform Write Protection SST25VF040B 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.

... A Microchip Technology Company Instructions Instructions are used to read, write (Erase and Program), and configure the SST25VF040B. The instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. Prior to execut- ing any Byte-Program, Auto Address Increment (AAI) programming, Sector-Erase, Block-Erase, Write- Status-Register, or Chip-Erase instructions, the Write-Enable (WREN) instruction must be executed first ...
