24LC02B/ST

Memory IC Overview

The Microchip Technology 24LC02B/ST is a 2-Kbit (256 x 8) serial EEPROM featuring an I²C-compatible two-wire interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write protection via the WP pin, an 8-byte page write buffer, and Schmitt trigger inputs for noise suppression. It offers over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin
• 8-byte page write buffer for efficient data transfer
• Schmitt trigger inputs with noise filtering

Memory IC Applications

• Embedded system configuration storage
• Calibration parameter persistence
• Firmware version tracking

Memory IC Procurement Notes

Verify that the ordering suffix '/ST' corresponds to the TSSOP-8 package type as specified in the manufacturer's documentation. Confirm the temperature grade matches the required operational environment, as industrial and extended grades are available within this product family. Ensure compatibility with the target I²C bus voltage levels before integration.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires low power consumption and simple serial connectivity. The 24LC02B is suitable for applications needing byte-level random access and hardware-based write protection. Consider the specific package availability and temperature range requirements relative to other variants in the 24LC02B series.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs from Microchip Technology. The family shares common architectural features such as the I²C interface and page write functionality but differs in operating voltage ranges and maximum clock speeds depending on the specific model designation.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different packages or temperature ratings, such as 24LC02B-I/SN or 24LC02B-E/ST. Cross-family replacements like 24AA02 or 24FC02 require verification of voltage compatibility and clock speed limitations.
