FM25640B - 5V F-RAM Memory

General Description

The FM25640B is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process.

A ferroelectric random access memory or F-RAM is nonvolatile but operates in other respects as a RAM.

Key Features

  • 64K bit Ferroelectric Nonvolatile RAM.
  • Organized as 8,192 x 8 bits.
  • High Endurance 1 Trillion (1012) Read/Writes.
  • 38 Year Data Retention.
  • NoDelay™ Writes.
  • Advanced high-reliability ferroelectric process Very Fast Serial Peripheral Interface - SPI.
  • Up to 20 MHz maximum bus frequency.
  • Direct hardware replacement for EEPROM.
  • SPI Mode 0 & 3 (CPOL, CPHA=0,0 & 1,1) Sophisticated Write Protection Scheme.
  • Hardware Protectio.
