24LC02BT-I/ST

Memory IC Overview

The Microchip Technology 24LC02BT-I/ST 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 TSSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication with Schmitt trigger inputs for noise suppression
• Includes an 8-byte page write buffer for efficient data transfer
• Provides hardware write protection via the WP pin to inhibit memory writes
• Features output slope control to eliminate ground bounce during operation

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 ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'ST' indicates the TSSOP package. Confirm the specific revision level matches the design requirements, as datasheet revisions may update electrical characteristics or pin descriptions without altering the core functionality.

Memory IC Selection Notes

Select this component when a 2-Kbit capacity is sufficient for the application. Ensure the system voltage remains above 2.5V, as lower voltages restrict the maximum clock frequency to 100 kHz. Verify that the host controller supports the required I²C protocol timing specifications for reliable data exchange.

Memory IC Part Context

This part belongs to the 24LC02B series of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA02 and 24FC02 devices but differs in minimum operating voltage and maximum clock speed capabilities. The 24LC02B is optimized for standard 3.3V and 5V logic systems.

Memory IC Replacement Considerations

The 24LC02BT-I/SN serves as a direct physical replacement offering identical electrical performance in an SOIC package. Cross-referencing with the 24AA02 or 24FC02 requires verifying voltage compatibility and bus speed limitations.
