The FM25040B-GTR is a 4-Kbit (512 × 8) serial ferroelectric random access memory (F-RAM) with high-endurance nonvolatile storage, supporting 100 trillion read/write cycles and 151-year data retention at 65°C. Operating from 4.5 V to 5.5 V, it features a fast SPI interface up to 20 MHz, advanced write protection, and low power consumption. Its robust operation across -40°C to +85°C and RoHS-compliant 8-pin SOIC package suit industrial, data logging, and control applications.

Features

  • 4-Kbit F-RAM organized as 512 × 8
  • 100 trillion read/write cycle endurance
  • 151-year data retention at 65°C
  • NoDelay™ writes, immediate data storage
  • Up to 20 MHz SPI interface
  • Direct hardware replacement for serial
  • Supports SPI mode 0 and mode 3
  • Hardware and software write protection
  • 250 μA active current at 1 MHz
  • 4 μA typical standby current
  • VDD operation from 4.5 V to 5.5 V
  • Operating temperature –40°C to +85°C

Benefits

  • Reliable nonvolatile storage for critical
  • Eliminates write delays for faster operation
  • Withstands frequent, rapid data updates
  • Prevents data loss during power cycles
  • Drop-in replacement simplifies upgrades
  • Flexible integration with SPI support
  • Protects data from accidental overwrites
  • Minimizes system power consumption
  • Suitable for harsh industrial environments
  • Long-term data retention reduces maintenance
  • Consistent performance over full voltage
  • Easy integration into existing designs
