Overview

The 24FC1025-I/P is a 1Mbit (128K x 8) Serial EEPROM from Microchip Technology, featuring a high-speed I2C interface capable of 1 MHz clock rates. It operates over a wide voltage range of 1.8V to 5.5V and is housed in an 8-pin PDIP package, making it ideal for high-capacity non-volatile storage in development and prototyping environments.

Why Choose This Part

This EEPROM offers high endurance with more than 1 million erase/write cycles and exceptional data retention of over 200 years. Its low power consumption, including a standby current of only 5 uA and active current of 0.45 mA, makes it suitable for battery-operated devices.

Applications

Firmware and Configuration Storage
Storing lookup tables, calibration constants, and device configuration parameters that must survive power cycles.
Data Logging
Recording sensor readings or system events in low-power remote monitoring applications using its 131,072 byte capacity.
Prototyping on Breadboards
The through-hole PDIP package allows for direct insertion into breadboards for testing memory expansion with MCUs like PIC or Arduino.
Large Page Buffering
Utilizing the 128-byte page write buffer to minimize write cycle overhead in applications requiring frequent updates.

Getting Started

Connect the device to an I2C bus with pull-up resistors on the SDA and SCL lines. Ensure the hardware write-protect pin is grounded for write access, and address the device according to the state of the A0 and A1 pins, which allow cascading up to four units on a single bus.
