24LC64FT-I/MS

Memory IC Overview

The Microchip Technology 24LC64FT-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, with a maximum access time of 900 ns. It utilizes low-power CMOS technology, offering standby current of 1 µA max and read current of 400 µA max. The component includes hardware write protection for the upper quarter of the array and is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial bus protocol compatible with standard I²C™ interfaces.
• Provides hardware write protection for the upper quarter of the memory array when the WP pin is tied high.
• Features a 32-byte page write buffer to optimize data writing efficiency through self-timed erase/write cycles.
• Includes Schmitt trigger inputs on SDA and SCL pins to suppress noise spikes and ensure signal integrity.

Memory IC Applications

• Personal communication devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I²C bus architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and packaging format. Confirm the voltage range requirements align with the 2.5V to 5.5V specification for the LC variant. Ensure the design accommodates the MSOP package dimensions and pinout configuration for proper surface mount assembly.

Memory IC Selection Notes

Select this part for designs requiring moderate density EEPROM with I²C compatibility. The LC series is suitable for applications operating at 2.5V or higher. Consider the FC series if operation below 2.5V or higher clock speeds are necessary. Verify address pin availability for multi-device bus configurations.

Memory IC Part Context

This component belongs to the 24XX64F family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA64F and 24FC64F, differing primarily in supply voltage ranges and maximum clock frequencies. The family is designed for low-power, non-volatile storage needs in compact electronic systems.

Memory IC Replacement Considerations

Direct substitutes include other 24LC64 variants with different packages such as 24LC64-I/SN or 24LC64-I/ST. Cross-family replacements like 24AA64F offer similar functionality but may require voltage level adjustments.
