The FM25L04B-DG is a 4-Kbit (512 × 8) nonvolatile ferroelectric RAM (F-RAM) with a high-speed SPI interface up to 20 MHz, supporting SPI modes 0 and 3. It delivers 100 trillion (1×10¹⁴) read/write cycles and 151-year data retention, surpassing serial flash and EEPROM in write speed and endurance.

Features

  • 4-Kbit F-RAM organized as 512 × 8
  • 100 trillion (10^14) read/write cycles
  • 151-year data retention at 65°C
  • NoDelay™ writes, writes at bus speed
  • Up to 20 MHz SPI interface
  • Hardware and software write protection
  • 200 μA active current at 1 MHz
  • 3 μA typical standby current
  • VDD operation from 2.7 V to 3.6 V
  • Industrial temp range: –40°C to +85°C
  • Direct hardware replacement for EEPROM/flash
  • Supports SPI mode 0 and mode 3

Benefits

  • Enables reliable nonvolatile storage
  • Withstands frequent data logging
  • Retains data for decades without power
  • Eliminates write delays for fast operation
  • Integrates easily with SPI microcontrollers
  • Protects data from accidental writes
  • Minimizes power usage in active mode
  • Extends battery life in standby
  • Operates in standard 3 V systems
  • Reliable in harsh industrial environments
  • Drop-in upgrade for legacy designs
  • Flexible for various SPI configurations
