24LC02BT/ST

Memory IC Overview

The Microchip Technology 24LC02BT/ST is a 2-Kbit (256 x 8) serial EEPROM utilizing 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 features a maximum access time of 900 ns and a page write buffer for eight bytes, with a self-timed write cycle of 5 ms maximum. It is available in surface-mount packages including SOIC and TSSOP, designed for industrial and extended temperature ranges.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard two-wire serial bus protocol
• Includes hardware write-protect functionality controlled by the WP pin
• Features Schmitt trigger inputs and noise suppression filters on SDA and SCL lines
• Provides output slope control to minimize ground bounce during operation

Memory IC Applications

• Data logging in embedded systems requiring non-volatile storage
• Configuration parameter storage for microcontroller-based devices
• Calibration data retention in industrial instrumentation
• Device identification and serial number storage in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix codes against official datasheets to confirm package type and temperature grade. Ensure supply chain sources provide valid RoHS compliance documentation. Confirm that ordering suffixes do not alter functional specifications unless explicitly stated in manufacturer literature. Validate component authenticity through authorized distribution channels.

Memory IC Selection Notes

Select this component when a 2-Kbit non-volatile memory solution is required with I²C connectivity. Consider the 2.5V minimum operating voltage constraint compared to lower-voltage alternatives. Evaluate the 8-byte page write buffer size against application write frequency requirements. Verify package availability matches PCB layout constraints for SOIC or TSSOP formats.

Memory IC Part Context

This device belongs to the 24XX02 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA02 and 24FC02 models but differs in operating voltage and speed capabilities. The family utilizes a common block diagram and bus protocol, facilitating design interchangeability within system architectures requiring small-capacity non-volatile storage.
