24LC02BT-E/MS

Memory IC Overview

The Microchip Technology 24LC02BT-E/MS 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 low-power CMOS technology with maximum active read current of 1 mA and standby current of 5 µA at extended temperatures. It includes an 8-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead MSOP package and is qualified for industrial and automotive applications.

Memory IC Feature Summary

• Hardware write protection capability via the WP pin to inhibit memory writes when tied to VCC
• Integrated 8-byte page write buffer to optimize data transfer efficiency
• Schmitt trigger inputs on SDA and SCL lines to suppress noise spikes
• Output slope control designed to eliminate ground bounce during operation

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Calibration data retention in automotive electronics
• Parameter storage in consumer electronic devices

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the Extended temperature range (-40°C to +125°C) and 'MS' specifies the 8-lead MSOP package. Confirm RoHS compliance status as required by project specifications. Ensure the supply voltage meets the minimum 2.5V requirement for this specific variant. Check for AEC-Q100 qualification if deploying in automotive environments.

Memory IC Selection Notes

Select this part when an I²C interface is required for non-volatile storage in space-constrained designs. The 24LC02BT-E/MS is suitable for applications needing hardware write protection and high endurance. Compare against the 24AA02B series if lower voltage operation below 2.5V is necessary. Consider the 24FC02 series if higher clock speeds up to 1 MHz are required.

Memory IC Part Context

This component belongs to the 24XX02 family of 2-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA02B and 24FC02, which share similar interfaces but differ in voltage ranges and clock speeds. The 24LC02B series specifically targets standard 2.5V to 5.5V applications with reliable performance across industrial and extended temperature grades.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different packages such as 24LC02BT-I/SN or 24LC02BT-E/ST. Cross-family replacements like the 24AA02B require verification of voltage compatibility. Ensure any replacement maintains the same I²C addressing and page size constraints.
