24CSM01T-E/MS

Memory IC Overview

The Microchip Technology 24CSM01T-E/MS is a 1-Mbit (131,072 x 8 bit) serial EEPROM featuring an I²C interface with High-Speed mode support up to 3.4 MHz. It operates within a voltage range of 1.7V to 5.5V and supports Extended temperature grades from -40°C to +125°C. The device includes built-in ECC logic for data reliability, a preprogrammed 128-bit serial number, and enhanced software write protection capabilities.

Memory IC Feature Summary

• Built-in Error Correction Code (ECC) logic capable of correcting single-bit errors within four-byte readouts.
• Security register containing a factory-programmed 128-bit unique serial number and user-programmable lockable ID page.
• Enhanced software write protection allowing configuration of independent memory zones via the Configuration register.
• High-speed I²C communication supporting Standard, Fast, Fast Mode Plus, and High-Speed modes.

Memory IC Applications

• Automotive systems requiring AEC-Q100 qualified nonvolatile memory
• Industrial control applications needing high-reliability data storage
• Embedded devices utilizing unique hardware identification for security
• Consumer electronics requiring robust write protection mechanisms

Memory IC Procurement Notes

Verify that the ordering suffix 'T' confirms tape-and-reel packaging and '/MS' specifies the 8-lead MSOP package. Confirm the '-E' suffix indicates the Extended temperature grade (-40°C to +125°C). Ensure compatibility with the required I²C bus speed and voltage levels before procurement.

Memory IC Selection Notes

Select this component when extended temperature operation is required alongside high-speed I²C communication. The 24CSM01T-E/MS is suitable for designs needing integrated security features like unique serial numbers and flexible write protection without external components. Compare against Industrial grade variants if lower temperature ranges suffice.

Memory IC Part Context

This part belongs to the 24CSM01 family of 1-Mbit serial EEPROMs manufactured by Microchip Technology. It shares core architectural features with other members of the series but differs in packaging and temperature rating. The T/E/MS suffix combination specifically defines the reel packaging, extended temperature range, and MSOP footprint.

Memory IC Replacement Considerations

Direct replacements must match the 1-Mbit capacity, I²C interface, and 8-lead MSOP package. Verify that substitute parts support the same voltage range and offer comparable write endurance and data retention specifications.
