24FC64FT-I/MNY

Memory IC Overview

The Microchip Technology 24FC64FT-I/MNY is a 64 Kbit (8K x 8) Electrically Erasable PROM featuring a 1 MHz I²C-compatible 2-wire serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports industrial temperature grades from -40°C to +85°C. The device includes a 32-byte page write buffer, hardware write-protect for the upper quarter of the array, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock frequency for rapid data transfer
• Includes hardware write-protect capability for the upper quarter of the memory array
• Features Schmitt trigger inputs to suppress noise spikes on serial lines
• Provides output slope control to eliminate ground bounce during operation

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Industrial embedded applications with strict size constraints

Memory IC Procurement Notes

Verify the specific suffix 'I/MNY' corresponds to the Industrial temperature grade (-40°C to +85°C) and TDFN-8 package configuration. Confirm that the ordering code matches the required reel or cut tape packaging format. Ensure compatibility with the 1 MHz I²C bus speed requirements of the target system design.

Memory IC Selection Notes

Select this component when a high-speed 1 MHz I²C interface is required alongside low standby current consumption. It is suitable for designs needing hardware write protection for critical data segments without software overhead. Consider the TDFN-8 package dimensions if board space is limited compared to standard SOIC or TSSOP options.

Memory IC Part Context

This part belongs to the 24XX64F family of EEPROMs, which share identical functional architectures but differ in maximum clock speeds and operating voltage ranges. The 'FC' designation specifically indicates the 1 MHz high-speed variant, distinguishing it from the 400 kHz 24AA64F and 24LC64F models within the same datasheet specification.

Memory IC Replacement Considerations

Direct functional substitutes include the 24AA64FT-I/MNY and 24LC64FT-I/MNY, though these operate at lower maximum clock frequencies of 400 kHz. Verify that the application timing margins accommodate the reduced speed of these alternative parts before substitution.
