24LC02BT-E/ST

Memory IC Overview

The Microchip Technology 24LC02BT-E/ST is a 2-Kbit (256 x 8) serial EEPROM featuring an I2C-compatible interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes an 8-lead TSSOP package and is rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 400 kHz I2C communication
• Includes hardware write protection via the WP pin
• Features Schmitt trigger inputs for noise suppression
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Non-volatile data storage in embedded systems
• Configuration parameter retention in consumer electronics
• Calibration data logging in industrial controllers
• Device identification and tracking in automotive modules

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the extended temperature grade (-40°C to +125°C). Confirm the '/ST' designation matches the required 8-lead TSSOP package. Ensure the supply voltage meets the minimum 2.5V requirement for this specific part variant.

Memory IC Selection Notes

Select this component when extended temperature operation is mandatory. The 24LC02B series requires a minimum supply voltage of 2.5V, unlike the 24AA02 which supports lower voltages. Verify that the 400 kHz speed is sufficient for the target application bus requirements.

Memory IC Part Context

This device belongs to the 24XX02 family of serial EEPROMs. It shares functional similarities with the 24AA02 and 24FC02 but differs in operating voltage and maximum clock frequency specifications. The 24LC02B specifically targets applications requiring robust performance at standard 3.3V or 5V logic levels.

Memory IC Replacement Considerations

The 24LC02BT-I/ST serves as a direct substitute if only industrial temperature ratings are needed. Other compatible packages include the 24LC02BT-E/SN (SOIC) and 24LC02BT-E/MC (DFN), provided the footprint allows.
