24FC64-I/MC

Memory IC Overview

The Microchip Technology 24FC64-I/MC is a 64-Kbit Electrically Erasable PROM organized as 8K x 8-bit memory. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 1 MHz. The device features a two-wire I2C compatible serial interface and is housed in an 8-lead DFN package (2x3 mm). Key electrical parameters include a maximum active current of 3 mA, standby current of 1 µA, and access time of 400 ns at 5.5V. It supports industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz clock operation for enhanced data throughput
• Includes hardware write-protect functionality via the WP pin
• Features Schmitt trigger inputs for improved noise suppression
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Industrial instrumentation calibration data retention

Memory IC Procurement Notes

Verify the specific suffix 'I/MC' corresponds to the Industrial temperature range (-40°C to +85°C) and the 8-lead DFN package format. Confirm RoHS compliance status and ensure the ordering quantity matches the manufacturer's standard tube packaging requirements for this specific footprint.

Memory IC Selection Notes

Select this component when a 1 MHz I2C interface speed is required compared to standard 400 kHz EEPROMs. Ensure the system power supply remains within the 1.7V to 5.5V operating range. Consider the 8-DFN package dimensions for PCB layout constraints and verify that the application utilizes the hardware write-protect feature if data integrity is critical.

Memory IC Part Context

This part belongs to the 24XX64 family of 64-Kbit I2C Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA64 and 24LC64 but offers higher clock speeds up to 1 MHz. The family provides various package options including MSOP, SOIC, and DFN formats to suit different board space requirements.

Memory IC Replacement Considerations

Direct functional substitutes within the same high-speed family include the 24FC64-I/MS (MSOP package) and 24FC64-I/SN (SOIC package). Verify pin compatibility and package dimensions before substituting with other series members like the 24LC64, which operates at lower clock speeds.
