24CSM01T-E/SN

Memory IC Overview

The Microchip Technology 24CSM01T-E/SN is a 1-Mbit (131,072 x 8) Serial EEPROM utilizing 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 features a SOIC-8 package. The device includes built-in ECC logic for data reliability, a preprogrammed 128-bit serial number, and enhanced software write protection. It supports byte and page writes up to 256 bytes with a maximum self-timed write cycle of 5 ms.

Memory IC Feature Summary

• Built-in Error Correction Code (ECC) logic capable of correcting single-bit errors within four-byte readouts.
• Preprogrammed globally unique 128-bit serial number stored in the Security register.
• Enhanced software write protection allowing configuration of eight independent 128-Kbit zones.
• High-speed I²C communication supporting Standard, Fast, Fast Mode Plus, and High-Speed modes.

Memory IC Applications

• Industrial control systems requiring reliable nonvolatile memory storage
• Automotive applications meeting AEC-Q100 qualification standards
• Consumer electronics needing device identification via serial numbers
• Embedded systems utilizing hardware or software-based data protection

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-Lead SOIC package type as documented in official datasheets. Confirm the temperature grade 'E' indicates Extended range operation (-40°C to +125°C). Ensure compatibility with the required I²C bus speed and voltage levels before integration into the design.

Memory IC Selection Notes

Select this component when high-speed data transfer rates up to 3.4 MHz are required alongside robust data integrity features. The inclusion of ECC logic makes it suitable for environments where bit-flips may occur. Consider the extended temperature range if the application operates in harsh thermal conditions beyond standard industrial limits.

Memory IC Part Context

This part belongs to the 24CSM01 family of 1-Mbit Serial EEPROMs from Microchip Technology. It shares core architectural features with other variants in the series but differs in package style and temperature rating. The 'T' suffix typically denotes tape and reel packaging, while 'E' specifies the extended temperature grade.

Memory IC Replacement Considerations

Direct replacements include other 24CSM01 variants such as 24CSM01-I/SM or 24CSM01-E/MS, provided the package footprint and temperature specifications align with the current design requirements. Verify pinout compatibility and electrical characteristics before substitution.
