24LC02BT-E/SN

Memory IC Overview

The Microchip Technology 24LC02BT-E/SN is a 2-Kbit (256 x 8) serial EEPROM utilizing an I²C 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 with a width of 3.90 mm and is rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection via the WP pin
• Schmitt trigger inputs for 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 the specific suffix 'E' confirms the extended temperature rating (-40°C to +125°C) and 'SN' indicates the 8-SOIC package. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the ordering code matches the required voltage and speed specifications for the target application environment.

Memory IC Selection Notes

Select this component when extended temperature operation is required alongside standard I²C compatibility. The 24LC02B series requires a minimum supply voltage of 2.5V, distinguishing it from lower-voltage variants like the 24AA02. The BT suffix denotes tape-and-reel packaging suitable for automated assembly processes.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs. It shares functional similarities with the 24AA02 and 24FC02 but differs in operating voltage and maximum clock frequency. The 24LC02B specifically targets applications requiring robust performance at higher voltages and extended thermal ranges compared to other family members.
