SST25PF020B

In Production

The 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. The SST25PF020B devices are enhanced with improved operating frequency and even lower power consumption. SST25PF020B SPI serial flash memories are manufactured with SST proprietary, high performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches....

  • Auto Address Increment (AAI) Programming - Decrease total chip programming time over Byte-Program operations
  • End-of-Write Detection - Software polling the BUSY bit in Status Register - Busy Status readout on SO pin in AAI Mode
  • Hold Pin (HOLD#) - Suspends a serial sequence to the memory without deselecting the device
  • Write Protection (WP#) - Enables/Disables the Lock-Down function of the status register
  • Software Write Protection - Write protection through Block-Protection bits in status register
  • Temperature Range - Commercial: 0°C to +70°C
  • Packages Available- 8-lead SOIC (150 mils)- 8-contact WSON (6mm x 5mm)
  • All non-Pb (lead-free) devices are RoHS compliant
