Memory IC datasheet and documents for 24LC128-E/SM

24LC128-E/SM

Memory IC Overview

The Microchip Technology 24LC128-E/SM is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates within a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via an I2C compatible two-wire serial interface. The device features a 64-byte page write buffer, hardware write-protect capability, and Schmitt trigger inputs for noise suppression. It is housed in an 8-Lead SOIJ package and is qualified for extended temperature operation from -40°C to +125°C.

Memory IC Feature Summary

Supports cascading up to eight devices on the same bus using configurable chip address inputs.
Includes hardware write-protect functionality to inhibit array writes when the WP pin is tied high.
Features output slope control designed to eliminate ground bounce during operation.

Memory IC Applications

Personal communications systems requiring non-volatile data storage
Data acquisition applications needing reliable memory retention
Embedded systems utilizing I2C serial interfaces

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the Extended temperature grade (-40°C to +125°C) and the SOIJ package style. Confirm compliance with RoHS directives and ensure the supply chain source provides valid traceability documentation for automotive or industrial qualification requirements.

Memory IC Selection Notes

Select this component when an I2C EEPROM requires operation at voltages starting from 2.5V rather than 1.7V. The Extended temperature rating makes it suitable for environments exceeding standard industrial limits. Ensure the application utilizes the SOIJ package format for board layout compatibility.

Memory IC Part Context

This part belongs to the 24LC128 family of 128Kbit I2C Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA128 and 24FC128 but is distinguished by its specific minimum operating voltage requirement of 2.5V and its designated temperature range classification.
