24C01CT-E/SN

Memory IC Overview

The Microchip Technology 24C01CT-E/SN is a 1-kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It features an I2C-compatible two-wire serial interface with a maximum clock frequency of 400 kHz. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V and is housed in an 8-lead SOIC package. It supports surface mount installation and guarantees data retention for over 200 years.

Memory IC Feature Summary

• Supports high-speed 400 kHz I2C communication protocol
• Includes hardware write protection capability
• Features self-timed erase and write cycles

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing standard I2C buses
• Automotive applications operating within extended temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'E' against official Microchip documentation to confirm it denotes the automotive grade variant (-40°C to +125°C), as standard industrial parts typically use 'I'. Ensure the datasheet confirms this specific suffix does not alter electrical parameters or pinouts compared to the standard 24C01C series. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Memory IC Selection Notes

Select this component when an I2C EEPROM is required for automotive environments due to its extended temperature range. Compare access times and power consumption against the industrial grade 24C01CT-I/SN if ambient conditions remain within commercial limits. Confirm that the 8-SOIC package fits the available PCB footprint and that the 4.5V minimum supply voltage aligns with the system power rail.

Memory IC Part Context

This part belongs to the Microchip 24C01C family of 1-kbit serial EEPROMs. The family offers various packaging options including SOIC, TSSOP, and DFN, alongside different temperature grades such as commercial, industrial, and automotive. The 24C01CT-E/SN specifically combines the automotive temperature rating with tape-and-reel packaging for automated assembly processes.

Memory IC Replacement Considerations

Direct replacements include the 24C01CT-I/SN for industrial temperature ranges or the 24C01A-ESM for similar automotive specifications. Verify pin compatibility and software register definitions before substituting.
