24LC128T-E/MF

Memory IC Overview

The Microchip Technology 24LC128T-E/MF 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 rated for industrial temperature ranges from -40°C to +125°C and utilizes an 8-lead DFN package.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using functional address lines A0, A1, and A2.
• Includes hardware write-protect functionality controlled by the WP pin to inhibit array writes.
• Features output slope control designed to eliminate ground bounce during operation.

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Low-power embedded memory storage

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the Extended temperature grade (-40°C to +125°C) and the DFN-8 surface mount package. Confirm RoHS compliance status and ensure the supply chain documentation matches the manufacturer's official specifications for this exact part number variant.

Memory IC Selection Notes

Select this component when an I2C interface with a 400 kHz maximum speed is required for non-volatile data retention. Ensure the system power supply remains stable between 2.5V and 5.5V. Consider the physical dimensions of the 8-lead DFN package against available PCB real estate and thermal management requirements.

Memory IC Part Context

This device belongs to the 24XX128 family, which includes the 24AA128 and 24FC128 variants. While sharing similar architecture, the 24LC128 is distinguished by its minimum operating voltage of 2.5V, whereas other family members support lower voltages or higher clock speeds depending on the specific sub-model designation.

Memory IC Replacement Considerations

Direct replacements include other 24LC128 variants with different packages such as SOIC-8 or TSSOP-8, provided the electrical characteristics and temperature grades match the application requirements.
