24LC02B-I/SN

Memory IC Overview

The Microchip Technology 24LC02B-I/SN 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 time of 5 ms. It is housed in an 8-lead SOIC package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin
• Schmitt trigger inputs with noise suppression
• Output slope control to eliminate ground bounce
• Self-timed erase/write cycles

Memory IC Applications

• Data logging systems
• Configuration storage
• Parameter memory
• Calibration data retention

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C). Confirm the 'SN' suffix indicates the 8-lead SOIC package. Ensure the specific revision matches the required datasheet version DS20001709N or later.

Memory IC Selection Notes

Select this component when a 2.5V minimum supply voltage is acceptable, as lower-voltage variants like the 24AA02 are not compatible below 2.5V. Verify that the 400 kHz speed limit meets system requirements, noting that the 24FC02 offers higher speeds.

Memory IC Part Context

This part belongs to the 24XX02 family, which includes the 24AA02 and 24FC02. While sharing the same physical footprint and basic interface, the 24LC02B is distinguished by its 2.5V minimum operating voltage and 400 kHz maximum clock frequency.

Memory IC Replacement Considerations

The 24LC02BHT-E/SN serves as a direct replacement if an extended temperature range (-40°C to +125°C) is required instead of the standard industrial range.
