The FM25W256-G is a 256-Kbit (32K × 8) serial F-RAM with an SPI interface, offering 100 trillion (1014) read/write cycles and 151-year data retention at 65°C. Operating from 2.7 V to 5.5 V with up to 20 MHz clock, it features NoDelay writes at bus speed, advanced write protection, and low active current (250 μA at 1 MHz). Housed in an 8-pin SOIC for –40°C to +85°C, it is ideal for frequent-write, nonvolatile memory in industrial and mission-critical systems.

Features

  • 256-Kbit F-RAM organized as 32K × 8
  • 100 trillion (10¹⁴) read/write cycles
  • 151-year data retention at 65°C
  • NoDelay™ writes, immediate data storage
  • Up to 20 MHz SPI bus operation
  • Sophisticated hardware and software write
  • Low active current: 250 μA at 1 MHz
  • Standby current: 15 μA typical
  • Wide voltage operation: 2.7 V to 5.5 V
  • Industrial temperature: –40°C to +85°C
  • Direct hardware replacement for serial
  • Supports SPI mode 0 and mode 3

Benefits

  • Reliable nonvolatile storage for critical
  • Eliminates write delays for real-time systems
  • Withstands frequent, rapid write operations
  • Prevents data loss in power failures
  • Reduces power consumption in standby
  • Flexible use across wide voltage applications
  • Operates in harsh industrial environments
  • Simplifies migration from flash/EEPROM
  • Enhanced data security with write protection
  • Fast SPI interface boosts system speed
  • No wear-out issues like flash/EEPROM
  • Easy integration with standard SPI
