... 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 SST25VF032B devices are enhanced with improved operating frequency which lowers power consumption. SST25VF032B SPI serial flash memories are manufactured with SST's proprie- tary, high-performance CMOS SuperFlash technology ...

... 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 program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies ...

... 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 ...
