This page describes the Plug & Program PNP-MEMFL32 FLASH memory storage module.

This module provides 32MBits / 4MBytes of Flash memory

Used in the Plug & Program NetSat1 Modular Embedded Web server to store user webpages but can be used in other applications for storing configuration information or data logging

Quick Look

  • 4MByte data storage module
  • High Reliability:
    • Endurance: 100,000 Cycles (typical)
    • Greater than 100 years Data Retention
  • SPI interface


  • SST (now Microchip subsidary) SST25VF032B SPI Serial Flash
  • Self contained unit, simple industry standard SPI interface to host controller
  • Byte writable for bytes in erased state BUT minimum erase operation is in 4 KByte blocks

IO Connectors

  • IO-SPI
    • IO-SPI.1 = SCK
    • IO-SPI.2 = SDO
    • IO-SPI.3 = SDI
    • IO-SPI.4 = CS/SS
