24FC64T-I/OT

Memory IC Overview

The Microchip Technology 24FC64T-I/OT is a 64-Kbit (8K x 8) I2C serial EEPROM. It operates on a single supply 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 features Schmitt trigger inputs, hardware write protection, and a 32-byte page write buffer. It utilizes an SOT-23-5 package.

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 hardware write protection via the WP pin to secure memory arrays

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage power supplies
• Embedded systems needing compact surface-mount memory solutions

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm voltage compatibility with the system design, as the FC series supports operation down to 1.7V. Ensure the application environment adheres to the specified industrial temperature range limits.

Memory IC Selection Notes

Select this component when high-speed I2C communication at 1 MHz is required within a small footprint. It is suitable for designs needing hardware write protection and low standby current. Compare against standard speed variants if bus timing constraints allow for slower operations.

Memory IC Part Context

This part belongs to the 24XX64 family of serial EEPROMs, which includes compatible variants like the 24AA64 and 24LC64. These devices share similar functional architectures but differ in maximum clock speeds and minimum operating voltages. The 'T' suffix indicates tape and reel packaging.

Memory IC Replacement Considerations

Direct substitutes include other 24FC64 variants such as 24FC64-I/SN or 24FC64-I/MS, provided the package type change is acceptable. Cross-family replacements like 24LC64 are possible only if lower clock speeds and higher minimum voltages fit the design.
