24LC128I

Product Overview

24LC128I is commonly associated with Microchip Technology 24LC128-I series serial EEPROM devices. The device provides 128 Kbit of non-volatile EEPROM memory organized as 16K x 8 bits and communicates through an I²C-compatible 2-wire serial interface. With broad voltage operation, low-power performance, 64-byte page write capability and random/sequential read support, it is suitable for configuration storage, calibration data, product ID storage, data logging, embedded control boards and maintenance or replacement projects.

Applications

24LC128I can be used in electronic systems that require medium-capacity I²C-compatible non-volatile memory. Typical applications include microcontroller configuration storage, product ID storage, calibration data retention, data logging, sensor modules, industrial control boards, consumer electronics, communication modules, medical electronics, maintenance projects and repair applications. It is also suitable for BOM review where a 128 Kbit serial EEPROM with I²C interface is required.
