24LC02BHT-E/MS

Memory IC Overview

The Microchip Technology 24LC02BHT-E/MS is a 2 Kbit (256 x 8) serial EEPROM featuring an I2C-compatible two-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write protection for the upper half of the memory array via the WP pin, an 8-byte page write buffer, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead MSOP package and rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array
• 8-byte page write buffer for efficient data transfer
• Schmitt trigger inputs with noise spike suppression
• Self-timed erase/write cycles with acknowledge polling

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage in consumer electronics
• Parameter retention in automotive modules
• Calibration data storage in sensor interfaces

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the MSOP package type and Extended temperature grade. Confirm RoHS compliance status as specified in the manufacturer's documentation. Ensure the component meets AEC-Q100 qualification requirements if intended for automotive applications. Cross-reference the datasheet revision to confirm electrical characteristics match system design specifications.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution is required with hardware-level write protection capabilities. The extended temperature range makes it suitable for harsh environments where standard industrial grades are insufficient. The low standby current and high endurance support long-term reliability in battery-powered or frequently accessed applications.

Memory IC Part Context

This part belongs to the 24XX02H family of serial EEPROMs, which share common architectural features such as the I2C interface and page write functionality. The 'E' suffix denotes the extended temperature range variant, while 'HT' indicates the specific package and tape-and-reel configuration. It complements other capacity variants within the same product line.

Memory IC Replacement Considerations

Direct replacements include other 24LC02BH variants with different packages such as SOIC or TSSOP, provided pin compatibility is maintained. Verify that substitute components offer equivalent write protection logic and operating voltage ranges to ensure functional interchangeability without circuit redesign.
