24FC64T-I/MF

Memory IC Overview

The Microchip Technology 24FC64T-I/MF is a 64-Kbit (8K x 8) Electrically Erasable PROM featuring an I2C-compatible two-wire serial interface. It operates within a supply voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz at VCC ≥ 2.5V, with compatibility down to 100 kHz at lower voltages. The device utilizes an 8-lead DFN package and functions across an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum active current of 3 mA, standby current of 1 µA, and a page write time of 5 ms.

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 throughput
• Features hardware write protection via the WP pin to secure memory arrays
• Provides Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices needing configuration parameter retention
• Low-power applications utilizing wide voltage input ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'MF' corresponds specifically to the 8-lead DFN package type required for your PCB layout. Confirm the 'I' designation matches the necessary industrial temperature operating range. Ensure the 'T' suffix aligns with the reel packaging specifications needed for your assembly process. Cross-reference the datasheet revision date to confirm all electrical parameters are current.

Memory IC Selection Notes

Select this component when a 1 MHz I2C clock speed is required compared to standard 400 kHz EEPROMs. Choose this part over the 24LC64 variant if operation below 2.5V is necessary, as it supports voltages down to 1.7V. Consider the 8-lead DFN package dimensions against available board space constraints. Verify that the application environment remains within the specified industrial temperature limits.

Memory IC Part Context

This device belongs to the 24XX64 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA64 and 24LC64 but offers distinct performance differences in clock speed and minimum operating voltage. The family provides various package options including MSOP, SOIC, and TDFN to accommodate different design requirements.

Memory IC Replacement Considerations

The 24FC64T-I/MS serves as a direct alternative in the MSOP-8 package. The 24FC64T-I/MNY is available in the 8-TDFN format. The 24FC64T-I/MC is offered in the 8-DFN(2x3) configuration. These parts share identical electrical specifications and functionality.
