24LC64T-E/MS

Memory IC Overview

The Microchip Technology 24LC64T-E/MS is a 64-Kbit Electrically Erasable PROM organized as 8K x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features a two-wire I2C compatible serial interface and supports page write operations with a 32-byte buffer. It is housed in an 8-lead MSOP package, rated for extended temperature operation from -40°C to +125°C, and includes hardware write protection.

Memory IC Feature Summary

• Two-wire serial interface compatible with I2C protocol
• Hardware write-protect capability via dedicated pin
• Supports cascading up to eight devices using address pins
• Schmitt trigger inputs for noise suppression

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications with high temperature requirements
• Automotive electronics utilizing AEC-Q100 qualified components
• Sensor calibration parameter retention

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'MS' indicates the 8-lead MSOP package. Confirm the 'T' designation matches the required tape and reel packaging format for automated assembly processes. Ensure compatibility with the system's I2C bus voltage levels.

Memory IC Selection Notes

Select this component when extended industrial or automotive temperature ranges are mandatory. The 2.5V minimum operating voltage distinguishes it from variants supporting lower voltages. The MSOP package offers a compact surface-mount solution suitable for space-constrained designs requiring robust environmental performance.

Memory IC Part Context

This part belongs to the 24LC64 series of 64-Kbit I2C Serial EEPROMs manufactured by Microchip Technology. The series provides electrically erasable and programmable read-only memory functionality. The specific model integrates automotive qualification standards alongside standard commercial specifications.

Memory IC Replacement Considerations

Direct replacements within the same family include 24LC64-E/MS (tube packaging) or 24LC64-I/MS (industrial temperature). Cross-family equivalents like 24AA64 or 24FC64 require verification of voltage range and clock speed differences.
