24FC64T-I/MS

Memory IC Overview

The Microchip Technology 24FC64T-I/MS is a 64-Kbit (8K x 8) Electrically Erasable PROM featuring an I2C-compatible two-wire serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V, with a maximum clock frequency of 1 MHz at VCC ≥ 2.5V. The device supports industrial temperature ranges (-40°C to +85°C) and utilizes an 8-lead MSOP package. Key electrical characteristics include a maximum active current of 3 mA, standby current of 1 µA, and access times as fast as 400 ns.

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the 'I' suffix indicates the Industrial temperature range (-40°C to +85°C). Ensure compatibility with the specific MSOP-8 footprint required by the design. Cross-reference the datasheet revision date to confirm feature consistency.

Memory IC Selection Notes

Select this component when high-speed 1 MHz communication is required over standard I2C buses. It is suitable for applications needing low-voltage operation down to 1.7V. Choose this part over 24LC64 variants if faster clock speeds are necessary. Ensure the system design accommodates the 32-byte page boundary constraints during write operations.

Memory IC Part Context

This part belongs to the 24XX64 family of 64-Kbit serial EEPROMs. It shares functional similarities with the 24AA64 and 24LC64 but offers distinct performance differences, specifically regarding maximum clock frequency and operating voltage ranges. The 'FC' designation typically denotes the high-speed variant within this product line.

Memory IC Replacement Considerations

Direct substitutes include other 24FC64 variants with different packages such as 24FC64-I/SN or 24FC64-I/MC. Verify pinout compatibility and ensure the replacement maintains the same voltage and speed specifications.
