24LC02BT/SN

Memory IC Overview

The Microchip Technology 24LC02BT/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 and is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication via I2C compatible interface
• Includes hardware write protection controlled by the WP pin
• Features Schmitt trigger inputs with noise suppression for reliable operation
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type, as these determine electrical characteristics. Confirm RoHS compliance status and ensure the component meets AEC-Q100 requirements if automotive qualification is necessary for the target application environment.

Memory IC Selection Notes

Select this part when a 2-Kbit capacity is sufficient for the application. Ensure the system power supply remains above 2.5V to maintain 400 kHz clock compatibility. Consider the 8-byte page buffer size when designing write algorithms to optimize bus throughput and prevent data overflow during sequential operations.

Memory IC Part Context

This component belongs to the 24XX02 family, which includes variants like the 24AA02 and 24FC02. While sharing similar physical packages and basic I2C protocols, the 24LC02B series is specifically optimized for 2.5V minimum operation, distinguishing it from lower-voltage or higher-speed counterparts within the same product line.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different temperature grades such as 24LC02BT-E/SN. Cross-family replacements like 24AA02 require verification of the minimum operating voltage constraints.
