Overview

The 24FC1025T-I/SN is a high-density 1Mbit (128K x 8) Serial EEPROM from Microchip Technology designed for non-volatile data storage applications. It utilizes a high-speed I2C interface capable of 1 MHz clock speeds and operates over a wide voltage range from 1.8V to 5.5V. This device features a 128-byte page write buffer and hardware write protection for secure data management.

Why Choose This Part

This EEPROM offers high endurance with over 1 million erase/write cycles and exceptional reliability with data retention exceeding 200 years. The inclusion of Schmitt Trigger inputs and output slope control ensures robust performance by suppressing noise and ground bounce in high-speed digital environments.

Applications

Firmware Parameter Storage
Storing configuration settings, calibration data, and lookup tables for microcontrollers in industrial and consumer electronics.
Data Logging
Recording sensor readings or event logs in battery-powered devices where low standby current of 5uA is critical.
User Preference Management
Retaining user-defined settings and state information across power cycles in smart home appliances.

Getting Started

To interface with this device, connect the I2C SDA and SCL lines with appropriate pull-up resistors to a microcontroller. Utilize the 128-byte page write buffer to optimize write cycle times, and ensure the hardware write-protect pin is tied to the desired state for data security. Developers can use standard I2C libraries such as the Microchip MPLAB Code Configurator (MCC) for rapid integration.
