FM25W256 - 256Kb Wide Voltage SPI F-RAM

Description

The FM25W256 is a 256-kilobit nonvolatile memory employing an advanced ferroelectric process.

A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM.

Features

  • 256K bit Ferroelectric Nonvolatile RAM.
  • Organized as 32,768 x 8 bits.
  • High Endurance 100 Trillion (1014) Read/Writes.
  • 38 Year Data Retention (@ +75ºC).
  • NoDelay™ Writes.
  • Advanced High-Reliability Ferroelectric Process Very Fast Serial Peripheral Interface - SPI.
  • Up to 20 MHz Frequency.
  • Direct Hardware Replacement for EEPROM.
  • SPI Mode 0 & 3 (CPOL, CPHA=0,0 & 1,1) Write Protection Scheme.
  • Hardware Protection.
