24LC02B-E/SN

Memory IC Overview

The Microchip Technology 24LC02B-E/SN is a 2-Kbit (256 x 8) serial EEPROM featuring an I²C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes an 8-lead SOIC package and is rated for extended industrial temperatures from -40°C to +125°C. Key electrical characteristics include a maximum active read current of 1 mA, standby current of 5 µA, and access time of 900 ns.

Memory IC Feature Summary

• Hardware write protection via the WP pin inhibits all write operations when tied to VCC
• Schmitt trigger inputs with noise suppression ensure reliable data transmission on noisy buses
• Internal page write buffer allows storage of up to eight bytes before initiating self-timed erase/write cycles
• Output slope control minimizes ground bounce effects during high-speed switching

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration parameter retention in automotive electronics
• Asset tracking identification modules

Memory IC Procurement Notes

Verify that the ordering suffix matches the specific temperature grade and package type required for your design. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement specifications. Ensure supply chain sources provide authentic components to maintain reliability standards.

Memory IC Selection Notes

Select this component when extended temperature operation up to 125°C is mandatory. The 24LC02B-E/SN variant specifically supports the 2.5V minimum supply voltage requirement unlike lower-voltage series. Verify that the 8-byte page write buffer aligns with application throughput requirements.

Memory IC Part Context

This part belongs to the 24LC02B family of serial EEPROMs designed for low-power applications. It shares architectural similarities with the 24AA02 and 24FC02 devices but differs in operating voltage ranges and maximum clock speeds. The E suffix denotes the extended temperature rating suitable for harsh environments.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different package options such as TSSOP or MSOP. Cross-reference with 24LC02BT-I/SN for automotive qualified versions if AEC-Q100 certification is required.
