24C02CT-E/MNY

Memory IC Overview

The Microchip Technology 24C02CT-E/MNY is a 2-kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes a 2-Wire I2C interface with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 4.5 V to 5.5 V and features an access time of 3.5 µs. It is housed in an 8-lead TDFN package and supports surface mount installation. The component ensures data retention for up to 200 years and functions across an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed I2C communication with a maximum clock frequency of 400 kHz
• Provides long-term non-volatile data storage with a 200-year retention guarantee
• Operates reliably in extreme environments with an extended industrial temperature range
• Includes hardware write protection capabilities via the WP pin

Memory IC Applications

• Storage of calibration data and configuration parameters in embedded systems
• Retention of user settings and device identifiers in consumer electronics
• Data logging applications requiring reliable non-volatile memory
• Industrial control systems operating under harsh environmental conditions

Memory IC Procurement Notes

Verify the specific suffix E/MNY against the official Microchip datasheet to confirm the electrical grade and package type. Ensure the design accommodates the 4.5 V minimum supply voltage requirement, as this variant differs from lower-voltage versions. Confirm that the TDFN-8 package dimensions align with the PCB footprint specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 400 kHz I2C speed and extended temperature range are required alongside standard 5 V logic levels. The 256-byte organization suits small data storage needs without the complexity of larger memory arrays. Consider the TDFN-8 package for compact surface-mount designs where space constraints limit the use of larger packages like SOIC or DIP.

Memory IC Part Context

This part belongs to the Microchip 24C series of serial EEPROMs, which are widely used for low-density non-volatile storage. The 24C02CT-E/MNY specifically targets applications requiring robust performance in industrial environments. It complements other variants in the family that may offer different voltage ranges or packaging options while maintaining compatible I2C protocol interfaces.

Memory IC Replacement Considerations

Direct substitutes include the 24C02CT-I/MNY, which shares the same package but offers a lower maximum operating temperature of 85°C. Verify compatibility if the application environment exceeds 85°C, as the 'I' grade is not rated for the full 125°C range specified for the 'E' grade version.
