24LC64F-I/MS

Memory IC Overview

The Microchip Technology 24LC64F-I/MS is a 64 Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It features a 2-wire serial interface compatible with I²C™ and operates on a single supply voltage ranging from 2.5V to 5.5V. The device supports clock frequencies up to 400 kHz and includes Schmitt trigger inputs for noise suppression. It offers hardware write protection for the upper quarter of the array, self-timed erase/write cycles, and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication via SDA and SCL pins
• Includes hardware write-protect capability for the upper quarter of the memory array
• Features output slope control to eliminate ground bounce during operation
• Provides over 1 million erase/write cycle endurance

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing byte-level parameter updates
• Industrial applications utilizing I²C bus architectures
• Power management circuits storing configuration settings

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range requirements align with the 2.5V minimum specification for the LC variant. Ensure the design accounts for the specific pinout of the MSOP package. Check for any recent product change notices regarding marking or packaging modifications.

Memory IC Selection Notes

Select this component when a 64 Kbit capacity is required with I²C compatibility. Choose the LC series specifically for applications operating at voltages starting at 2.5V. Consider the MSOP package for space-constrained surface mount designs. Verify that the 400 kHz maximum clock frequency meets the system timing requirements.

Memory IC Part Context

This part belongs to the 24XX64F family of serial EEPROMs manufactured by Microchip Technology. The family includes variants with different voltage ranges and clock speeds, such as the AA and FC series. The 'I' designation indicates an industrial temperature range rating. The 'MSOP' suffix identifies the specific 8-lead micro-small outline package geometry.

Memory IC Replacement Considerations

Direct substitutes within the same family include other 24LC64F variants with different packages, such as 24LC64F-I/SN or 24LC64F-I/P. Cross-family replacements like the 24AA64F or 24FC64F require verification of voltage and speed compatibility.
