Overview

The FM25C160B-GTR is a 16Kbit non-volatile Ferroelectric RAM (F-RAM) organized as 2K x 8 bits and accessed via a high-speed 20 MHz SPI interface. Unlike standard EEPROM, this F-RAM offers NoDelay writes and extreme endurance of 100 trillion cycles, making it ideal for high-frequency data logging in 5V systems. It operates over a voltage range of 4.5V to 5.5V and maintains data integrity for over 151 years.

Why Choose This Part

This device provides 100 trillion read/write cycles, effectively eliminating the endurance limitations of EEPROM and Flash. It features NoDelay writes, where data is written to the memory cell at bus speed without requiring a self-timed write cycle, and consumes only 4uA in standby mode.

Applications

High-Frequency Event Logging
Captures system state data and error logs in real-time without the write delays or wear-out concerns associated with traditional non-volatile memory.
Industrial Controller Configuration
Stores calibration constants and configuration parameters that require frequent updates during automated tuning processes.
Smart Metering
Records continuous usage data in utility meters where power-loss protection and high write-cycle counts are critical.
Motor Control Position Storage
Reliably saves encoder positions and motor state variables during sudden power-down events to facilitate immediate recovery.

Getting Started

Interface this memory to any 5V microcontroller using a standard four-wire SPI bus (CS, SCK, SI, SO). Ensure the VDD supply remains within the 4.5V to 5.5V range and use the hardware Write Protect (WP) pin for additional data security during power-up sequences.
