24LC024T/ST

Memory IC Overview

The Microchip Technology 24LC024T/ST is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and features a 2-wire I²C compatible interface with a maximum clock frequency of 400 kHz. The device supports page write operations with a 16-byte buffer and includes hardware write protection via the WP pin. It is housed in an 8-lead TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on a single bus using hardware address pins for expanded memory addressing.
• Includes Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce during operation.
• Features self-timed erase/write cycles with automatic acknowledgment polling to maximize bus throughput.

Memory IC Applications

• Data logging systems requiring non-volatile storage for sensor readings or event timestamps.
• Configuration storage for microcontroller-based embedded systems.
• Calibration data retention in industrial instrumentation.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type, as the base part number covers multiple variants. Confirm RoHS compliance status and ensure the supplier provides valid traceability codes consistent with Microchip marking standards. Check for any recent Product Change Notifications regarding assembly locations or materials.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM with hardware write protection is required. Ensure the system voltage remains above 2.5V, as lower voltages restrict the maximum clock speed to 100 kHz. Consider the 24LC025 if hardware write protection is not needed, or the 24AA series if operation below 2.5V is necessary.

Memory IC Part Context

This device belongs to the 24AA024/24LC024 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC025 but distinguishes itself through the inclusion of a dedicated hardware write-protect pin. The 'T' suffix indicates tape and reel packaging, while '/ST' denotes the 8-lead TSSOP physical package format.

Memory IC Replacement Considerations

The 24LC025 serves as a direct functional substitute if hardware write protection is unnecessary. For applications requiring operation below 2.5V, the 24AA024 is the appropriate alternative. Verify that any replacement maintains the same I²C protocol compatibility and package dimensions.
