24FC64T-I/SN

Memory IC Overview

The Microchip Technology 24FC64T-I/SN is a 64-Kbit (8K x 8) serial EEPROM featuring an I2C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device supports industrial temperature ranges (-40°C to +85°C) and includes hardware write protection via the WP pin. It utilizes low-power CMOS technology, offering a standby current of 1 µA maximum and active current of 3 mA maximum.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation for efficient data transfer
• Includes a 32-byte page write buffer to optimize write performance
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Smart metering applications demanding long-term data integrity

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging as specified in official documentation. Confirm the 'I' suffix indicates the industrial temperature grade range. Ensure the SN package designation matches the required SOIC footprint for your PCB layout.

Memory IC Selection Notes

Select this component when a 1 MHz I2C interface speed is required compared to standard 400 kHz devices. It is suitable for designs operating down to 1.7V, unlike the 2.5V minimum 24LC64 variant. The SOIC-8 package provides a standard surface-mount form factor for general-purpose integration.

Memory IC Part Context

This part belongs to the 24XX64 family of 64-Kbit serial EEPROMs. It shares functional architecture with the 24AA64 and 24LC64 but offers distinct electrical characteristics, specifically higher clock speeds and lower voltage operation thresholds defined by its specific series designation.

Memory IC Replacement Considerations

The 24FC64-I/SN is the tube-packaged equivalent of the same die and specifications. Other 24FC64 variants exist in different packages such as MSOP or DFN.
