24LC02BT-E/MNY

Memory IC Overview

The Microchip Technology 24LC02BT-E/MNY is a 2-Kbit (256 x 8) serial EEPROM featuring an I²C interface with a maximum clock frequency of 400 kHz. It operates within a voltage range of 2.5 V to 5.5 V and supports industrial (-40°C to +85°C) and extended (-40°C to +125°C) temperature ranges. The device includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control. 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
• Schmitt trigger inputs for enhanced noise suppression
• Output slope control designed to eliminate ground bounce
• Self-timed erase/write cycle with page write buffer

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter memory in consumer electronics
• Asset tracking identification modules

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature rating up to +125°C and the 'MNY' designation corresponds to the TDFN package. Confirm RoHS compliance status as required by project specifications. Ensure the operating voltage supply aligns with the minimum 2.5 V requirement for this specific device variant.

Memory IC Selection Notes

Select this component when extended temperature operation up to +125°C is required alongside standard I²C compatibility. The TDFN package suits space-constrained surface-mount designs. Consider the 400 kHz speed limit if higher bus frequencies are needed, or verify that the 2.5 V minimum voltage meets system power rails.

Memory IC Part Context

This part belongs to the 24LC02B series of 2-Kbit serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA02 and 24FC02 but differs in voltage range and clock speed capabilities. The 24LC02B specifically targets applications requiring robust operation at 2.5 V to 5.5 V without the lower voltage support of the 24AA02.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different packages such as SOIC or MSOP. Cross-family replacements like 24AA02 require verification of voltage compatibility due to its 1.7 V lower limit.
