24LC02BHT-E/OT

Memory IC Overview

The Microchip Technology 24LC02BHT-E/OT is a 2 Kbit (256 x 8) serial EEPROM featuring an I2C interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes a 5-lead SOT-23 package and offers an access time of 900 ns. It provides over one million erase/write cycles, data retention exceeding 200 years, and functions across an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Schmitt trigger inputs with noise suppression on SDA and SCL lines
• On-chip 8-byte page write buffer for efficient data transfer
• Self-timed erase and write cycles with automatic termination

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in automotive electronics
• Calibration data storage in consumer devices

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and 'OT' specifies the SOT-23-5 package. Confirm the '24LC02BH' base indicates the 2.5V minimum operating voltage requirement. Ensure compatibility with the host system's I2C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small capacity non-volatile storage. The 24LC02BHT-E/OT is suitable for applications needing hardware-level write protection for critical data segments. Consider the 400 kHz speed limit and 2.5V minimum supply voltage against system power constraints and bus timing requirements.

Memory IC Part Context

This part belongs to the 24XX02H family of 2-Kbit I2C Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different voltage ranges and temperature grades. The 24LC02BH series specifically targets applications requiring operation at voltages starting from 2.5V, distinguishing it from the lower-voltage 24AA02H series.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02BH variants with different packages such as 24LC02BH-E/SN or 24LC02BH-E/ST. Cross-family replacements like 24AA02BH may require voltage level adjustments due to lower minimum operating voltages.
