The FM31276-G is a 64-Kbit processor companion with ferroelectric random access memory (F-RAM), offering 100 trillion read/write endurance and 151-year data retention. It integrates a real-time clock, programmable low-VDD reset, watchdog timer, dual battery-backed event counters, and a lockable 64-bit serial number. Operating from 4.0 V to 5.5 V at -40°C to +85°C, it supports I2C up to 1 MHz. The device is housed in a 14-pin SOIC package for industrial systems.

Features

  • 64-Kbit/256-Kbit F-RAM nonvolatile memory
  • Up to 100 trillion read/write cycles
  • 151-year data retention at 65°C
  • NoDelay™ writes, I2C interface up to 1 MHz
  • Real-time clock with battery/capacitor backup
  • Programmable watchdog timer (100 ms–3 s)
  • Dual battery-backed event counters
  • Early power-fail comparator with NMI
  • 64-bit programmable serial number with lock
  • Programmable low-VDD reset (3.9 V/4.4 V)
  • Low active current: 1.5 mA at 1 MHz
  • Wide operating voltage: 4.0 V to 5.5 V

Benefits

  • Replaces multiple parts, simplifies design
  • Virtually unlimited endurance, no wear-out
  • Reliable data retention for decades
  • Instant writes, no wait for memory store
  • Maintains time and events during power loss
  • Prevents software lockup with watchdog
  • Tracks system events for security/audit
  • Early warning prevents data corruption
  • Secure device ID for traceability
  • Ensures robust reset on power faults
  • Low power extends battery/system life
  • Operates in standard 5 V systems
