24LC64FT-E/SN

Memory IC Overview

The Microchip Technology 24LC64FT-E/SN is a 64 Kbit Electrically Erasable PROM organized as an 8K x 8-bit memory block. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I2C compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features industrial temperature range operation from -40°C to +85°C, housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Hardware write-protect capability for the upper quarter of the memory array
• 32-byte page write buffer for efficient data transfer
• Schmitt trigger inputs designed for noise suppression
• Output slope control implemented to eliminate ground bounce

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Embedded controllers utilizing I2C bus architecture

Memory IC Procurement Notes

Verify that the specific suffix 'E' confirms automotive-grade temperature ratings (-40°C to +125°C) if required, while 'I' denotes industrial grades. Confirm the 'T' indicates tape-and-reel packaging suitable for automated assembly processes. Ensure compatibility with the 2.5V minimum operating voltage specified for the LC series.

Memory IC Selection Notes

Select this component when a 64 Kbit EEPROM with hardware write protection is necessary. The 8-pin SOIC package suits surface mount applications. Verify that the 400 kHz maximum clock frequency meets system timing requirements. Consider the 32-byte page buffer size for optimizing write throughput in the target design.

Memory IC Part Context

This part belongs to the 24XX64F family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like 24AA64F and 24FC64F, distinguished primarily by their operating voltage ranges and maximum clock speeds. The 24LC64F specifically targets standard 2.5V to 5.5V applications.

Memory IC Replacement Considerations

Direct substitutes within the same package and specification include other 24LC64F variants such as 24LC64FT-I/SN for industrial temperature grades.
