24LC64F-E/MS

Memory IC Overview

The Microchip Technology 24LC64F-E/MS is a 64 Kbit Electrically Erasable PROM organized as 8K x 8-bit memory. It features a 2-wire I²C compatible serial interface and operates on a single supply voltage ranging from 2.5V to 5.5V. The device supports clock frequencies of up to 400 kHz and includes hardware write-protect functionality for the upper quarter of the array. Designed for industrial applications, it functions within a temperature range of -40°C to +125°C and is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Hardware write-protect capability for the upper 1/4 of the memory array via the WP pin
• Supports cascading up to eight devices on the same bus using functional address inputs A0, A1, and A2
• Includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce

Memory IC Applications

• Personal communications systems requiring non-volatile data storage
• Data acquisition systems needing low-power configuration retention
• Industrial embedded controllers utilizing I²C bus communication

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required automotive temperature grade (-40°C to +125°C) and the MSOP surface-mount package type. Confirm that the component meets RoHS compliance standards and Pb-Free requirements before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when an I²C EEPROM with automotive-grade temperature stability is required. Ensure the system power supply remains within the 2.5V to 5.5V operational range. Verify that the application utilizes the 2-wire serial interface protocol and requires hardware-level write protection for critical memory segments.

Memory IC Part Context

This part belongs to the 24XX64F family of 64 Kbit serial EEPROMs manufactured by Microchip Technology. The 'E' suffix denotes the extended automotive temperature range, while 'MSOP' indicates the specific 8-lead Mini Small Outline Package. It shares core architecture with the 24AA64F and 24FC64F variants but differs in voltage tolerance and maximum clock frequency specifications.

Memory IC Replacement Considerations

Direct substitutes include other 24LC64F variants with different packages such as SOIC or TSSOP, provided the pinout remains identical. Cross-referencing with the 24LC64 datasheet is necessary to ensure compatibility regarding voltage ranges and interface timing if replacing with non-F series components.
