24LC64FT-I/MNY

Memory IC Overview

The Microchip Technology 24LC64FT-I/MNY 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™ standards and operates within a supply voltage range of 2.5V to 5.5V. The device supports maximum clock frequencies of 100 kHz at voltages below 2.5V and 400 kHz between 2.5V and 5.5V. It utilizes low-power CMOS technology, ensuring standby current remains at or below 1 µA in industrial temperature grades. The component includes a 32-byte page write buffer and provides hardware write protection for the upper quarter of the array.

Memory IC Feature Summary

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

Memory IC Applications

• Personal communications systems requiring low-power non-volatile storage
• Data acquisition applications needing reliable parameter retention
• Industrial equipment utilizing I²C-compatible serial interfaces

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device version corresponds to the F-series specifications regarding voltage ranges and clock compatibility. Ensure procurement channels provide original manufacturer documentation to validate authenticity and compliance with RoHS standards before integration into production designs.

Memory IC Selection Notes

Select this component when a 64 Kbit capacity with I²C compatibility is required alongside specific hardware write protection for critical data segments. Consider the TDFN package for surface mount applications where space efficiency is prioritized. Evaluate the operating voltage constraints to ensure compatibility with the system's power supply rails, noting the minimum 2.5V requirement for this specific variant.

Memory IC Part Context

This part belongs to the 24XX64F family of serial EEPROMs from Microchip Technology. The family shares common architectural features including the 2-wire serial interface and page write capabilities. Variants within the series differ primarily in operating voltage ranges, maximum clock speeds, and available package options to suit diverse design requirements.

Memory IC Replacement Considerations

Direct replacements include other members of the 24LC64F series such as 24LC64F-I/ST or 24LC64F-I/SN, provided the package footprint and electrical characteristics align with the existing design constraints.
