Overview

The 24FC1025-I/SN is a high-density 1Mbit serial EEPROM from Microchip Technology, organized as 128K x 8-bit. It supports high-speed I2C communications up to 1 MHz and features a wide operating voltage range from 1.8V to 5.5V, making it suitable for a variety of low-power and standard voltage systems.

Why Choose This Part

The device offers robust endurance with more than 1 million erase/write cycles and over 200 years of data retention. It features a 128-byte page write buffer and Schmitt Trigger inputs for noise suppression, along with hardware write-protection to prevent accidental data loss.

Applications

Configuration Storage
Storing calibration data, user settings, and network configuration parameters in embedded systems.
Data Logging
Recording sensor readings or event logs in industrial and consumer devices where non-volatile memory is required.
Firmware Backup
Acting as a secondary storage location for bootloaders or firmware patches to facilitate field updates.

Getting Started

To interface with this EEPROM, connect the SDA and SCL pins to your microcontroller's I2C bus with appropriate pull-up resistors. Ensure the A0, A1, and A2 pins are tied to Vcc or GND to set the device address, and use the 1.8V to 5.5V supply range to match your system logic level.
