The FM31256-GTR is a 256-Kbit processor companion integrating nonvolatile F-RAM, a real-time clock/calendar, and supervisory functions in a 14-pin SOIC. It features 32K × 8 memory, 100 trillion read/write cycles, and 151-year data retention. Key functions include a programmable watchdog timer, low-VDD reset, dual event counters, and a 64-bit lockable serial number.

Features

  • F-RAM with 100 trillion read/write cycles
  • 151-year data retention
  • NoDelay™ instant writes
  • Real-time clock/calendar with leap year
  • Programmable watchdog timer (100 ms–3 s)
  • Early power-fail comparator
  • Dual battery-backed event counters
  • 64-bit programmable, lockable serial number
  • I2C interface up to 1 MHz
  • Software memory write protection
  • Programmable low-VDD reset (2.6–4.4 V)
  • Low power: 1.5 mA active, 150 μA standby

Benefits

  • Virtually unlimited write endurance
  • Reliable long-term data storage
  • Instant writes eliminate wait times
  • Accurate timekeeping, leap year support
  • Prevents processor lockups
