24LC02B-E/P

Memory IC Overview

The Microchip Technology 24LC02B-E/P is a 2-Kbit (256 x 8) serial EEPROM utilizing 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 features a maximum access time of 900 ns and a page write buffer for 8 bytes, with a self-timed write cycle of 5 ms maximum. It is housed in an 8-lead PDIP package and rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin
• Schmitt trigger inputs for noise suppression
• Output slope control to eliminate ground bounce
• High endurance exceeding one million erase/write cycles

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Calibration data retention in automotive electronics

Memory IC Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and the 'P' suffix indicates the 8-lead PDIP package. Confirm compliance with RoHS directives and ensure the supply voltage meets the minimum 2.5V requirement for this specific variant. Check datasheet revisions for any recent manufacturing changes.

Memory IC Selection Notes

Select this component when an I²C serial EEPROM is required for applications operating between 2.5V and 5.5V. The extended temperature grade is suitable for harsh industrial or automotive conditions. Ensure the system design accommodates the 400 kHz bus speed and utilizes the hardware write-protect feature if data integrity against accidental writes is critical.

Memory IC Part Context

This part belongs to the 24XX02 family, which includes the 24AA02 and 24FC02 variants. While sharing similar architecture, the 24LC02B is distinguished by its 2.5V minimum operating voltage compared to the 1.7V minimum of the 24AA02/24FC02. The 'E' designation specifically denotes the extended temperature rating, differentiating it from the standard industrial 'I' grade.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different packages (e.g., SOIC, MSOP) or temperature grades (I/SN). Cross-family replacements like 24AA02 require verification of the lower voltage threshold compatibility.
