24FC01-E/MS

Memory IC Overview

The Microchip Technology 24FC01-E/MS is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead MSOP package. It features a 2-wire I2C compatible serial interface with a maximum clock frequency of 1 MHz when operating between 1.7V and 5.5V. The device supports extended temperature operation from -40°C to +125V. Key electrical characteristics include a maximum access time of 450 ns, a page write time of 5 ms, and low standby current consumption.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication for efficient data transfer
• Includes hardware write protection via the WP pin to prevent unauthorized modifications
• Features Schmitt trigger inputs and noise filtering for reliable operation on noisy buses
• Provides self-timed erase/write cycles with automatic acknowledgment polling

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics applications meeting AEC-Q100 standards
• Consumer devices needing compact memory solutions with wide voltage tolerance
• Embedded systems utilizing I2C bus architectures for configuration storage

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'MS' denotes the 8-lead MSOP package. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering code matches the required voltage and speed specifications for your design.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C performance is required alongside extended temperature capabilities. It is suitable for designs needing robust noise immunity and hardware write protection. Compare against the 24AA01 or 24LC01B if lower speed or different voltage constraints apply.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA01 and 24LC01B but offers superior 1 MHz clock compatibility. The family utilizes a common block diagram and bus protocol, differing primarily in speed grades and temperature ranges.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24FC01-I/MS for industrial temperature range. Other packages like 24FC01T-E/OT or 24FC01T-I/ST offer alternative form factors. Cross-brand replacements require verification of I2C timing and voltage levels.
