The FM24W256-G is a 256-Kbit (32K × 8) serial F-RAM with I2C interface, providing high-endurance nonvolatile memory for frequent data logging and industrial control. It supports 100 trillion (1014) read/write cycles, 151-year data retention at 65°C, and operates from 2.7 V to 5.5 V over –40°C to +85°C. With up to 1 MHz I2C speed, NoDelay™ writes, and low power consumption, it is a reliable drop-in replacement for serial EEPROM in demanding applications.

Features

  • 256-Kbit F-RAM organized as 32K × 8
  • 100 trillion (10¹⁴) read/write cycles
  • 151-year data retention at 65°C
  • NoDelay™ instant write operation
  • I2C interface up to 1 MHz
  • Low active current: 100 μA at 100 kHz
  • 15 μA typical standby current
  • VDD operation: 2.7 V to 5.5 V
  • Industrial temp range: –40°C to +85°C
  • Direct hardware replacement for I2C EEPROM
  • Supports 100 kHz, 400 kHz, 1 MHz I2C
  • Advanced high-reliability ferroelectric

Benefits

  • Enables frequent, fast data logging
  • Eliminates write delays for real-time systems
  • Reliable data storage for over a century
  • Reduces system power consumption
  • Simplifies design with wide voltage range
  • Operates in harsh industrial environments
  • Drop-in replacement for legacy EEPROM
  • Supports legacy and high-speed I2C
  • No wear-out concerns in write-intensive use
  • Low standby current extends battery life
  • No data polling needed after writes
  • High reliability for mission-critical data
