The FM31276-GTR is a 64-Kbit processor companion with F-RAM, integrating nonvolatile memory, real-time clock, and processor supervisory functions in a 14-pin SOIC package. It delivers 100 trillion read/write cycles, 151-year data retention at 65°C, and operates from 4.0 V to 5.5 V across -40°C to +85°C. Features include programmable low-VDD reset, watchdog timer, battery-backed event counters, lockable 64-bit serial number, and I2C interface up to 1 MHz.

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
