24LC512-E/SM

Memory IC Overview

The Microchip Technology 24LC512-E/SM is a 512 Kbit (64K x 8) serial electrically erasable PROM featuring an I²C compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes an 8-lead SOIJ package and is qualified for extended industrial temperature ranges from -40°C to +125°C.

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 protection via the WP pin to inhibit array writes when tied to VCC.
• Features a 128-byte page write buffer to allow efficient sequential data storage.

Memory IC Applications

• Data acquisition systems requiring non-volatile parameter storage
• Personal communications devices needing low-power memory
• Embedded controllers storing calibration data or configuration logs

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'SM' specifies the 8-lead SOIJ package. Confirm the manufacturer is Microchip Technology Inc. Ensure the component matches the RoHS compliant status indicated in the official datasheet DS20001754Q.

Memory IC Selection Notes

Select this part when operation below 2.5V is not required, as the 24LC512 series minimum is 2.5V compared to 1.7V for the 24AA512. Choose the E grade for environments exceeding standard industrial limits. The SM package is suitable for surface mount assembly with specific footprint requirements.

Memory IC Part Context

This component belongs to the 24XX512 family of 512 Kbit Serial EEPROMs. It shares architectural similarities with the 24AA512 and 24FC512 but differs in voltage specifications and maximum clock frequency capabilities. The family supports both random and sequential read operations across the full memory boundary.

Memory IC Replacement Considerations

The 24LC512-I/SM serves as the industrial temperature variant of this component. For lower voltage applications, the 24AA512-E/SM is a compatible alternative within the same package.
