24LC024/ST

Memory IC Overview

The Microchip Technology 24LC024/ST is a 2 Kbit (256 x 8) serial Electrically Erasable PROM utilizing an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control. It offers high endurance with over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin
• I²C compatible bidirectional serial interface
• Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

• Embedded systems requiring non-volatile parameter storage
• Industrial control devices needing configuration memory
• Consumer electronics with low-power EEPROM requirements

Memory IC Procurement Notes

Verify that the specific part number corresponds to the TSSOP package variant as indicated by the suffix. Confirm the temperature grade matches the application environment, distinguishing between Industrial and Automotive ratings. Ensure the ordering code aligns with the required packaging format and RoHS compliance status before finalizing procurement.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for the application's data storage needs. Choose this model over the 24AA024 if the system operates exclusively within the 2.5V to 5.5V range, as it does not support voltages below 2.5V. Consider the 24LC025 if hardware write protection is not required or if a different package option like SOT-23 is preferred.

Memory IC Part Context

This device belongs to the 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares functional similarities with other members of the series but is distinguished by its specific voltage operating range and lack of hardware write protection in the '24LC025' variant. The '/ST' suffix denotes the TSSOP package type.

Memory IC Replacement Considerations

Direct replacements include the 24AA024, provided the system voltage remains above 2.5V. The 24LC025 serves as a substitute if write protection is unnecessary. Verify package compatibility and temperature ranges when substituting.
