24C02CT-E/SN

Memory IC Overview

The Microchip Technology 24C02CT-E/SN is a 2Kb (256 x 8) serial electrically erasable programmable read-only memory (EEPROM) integrated circuit. It utilizes an I2C interface with a maximum clock frequency of 100 kHz and features a 3.5 µs access time. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in an 8-SOIC package. It is designed for industrial temperature applications, functioning reliably between -40°C and +125°C.

Memory IC Feature Summary

• Supports standard I2C communication protocol with hardware address inputs for multi-device bus configurations
• Provides non-volatile data storage with high endurance and long-term retention capabilities
• Includes write protection functionality to prevent accidental data modification

Memory IC Applications

• Storage of calibration parameters and configuration settings in embedded systems
• Retention of user-defined data and device identification information
• Small-scale data logging and history caching in industrial controllers

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +125°C), distinguishing it from commercial variants. Confirm the 'SN' designation corresponds to the 8-SOIC package type. Ensure the 'CT' prefix aligns with the required tape and reel packaging format for automated assembly processes.

Memory IC Selection Notes

Select this component when an I2C EEPROM requires operation at temperatures up to 125°C. The 100 kHz clock speed suits standard mode applications where high-speed data transfer is not critical. Verify that the 4.5V minimum supply voltage requirement matches the system power rails, as lower voltage options exist within the broader product family.

Memory IC Part Context

This part belongs to the Microchip 24C02C series of serial EEPROMs. It shares architectural similarities with other members like the 24C02CT/SN but differs in operating temperature specifications. The series is widely used in consumer and industrial electronics for persistent data storage requiring low pin counts and simple interface protocols.

Memory IC Replacement Considerations

The 24C02CT/SN serves as a direct functional substitute if the application does not require the extended industrial temperature rating. Other compatible alternatives include the 24AA02 series, though voltage and speed characteristics must be verified against specific design constraints.
