FM31L276 - 64-Kbit/256-Kbit Integrated Processor Companion

General Description

The FM31L276/FM31L278 device integrates F-RAM memory with the most commonly needed functions for processor-based systems.

Key Features

  • 64-Kbit/256-Kbit ferroelectric random access memory (F-RAM).
  • Logically organized as 8K × 8 (FM31L276)/ 32K × 8 (FM31L278).
  • High-endurance 100 trillion (1014) read/writes.
  • 151-year data retention (See Data Retention and Endurance on page 29).
  • NoDelay™ writes.
  • Advanced high-reliability ferroelectric process.
  • High Integration Device Replaces Multiple Parts.
  • Serial nonvolatile memory.
  • Real time clock (RTC).
  • Low voltage reset.
  • Watchdog timer.
