24LC024HT-E/SN

Memory IC Overview

The Microchip Technology 24LC024HT-E/SN is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 1 MHz. The device includes Schmitt trigger inputs for noise suppression, output slope control to eliminate ground bounce, and hardware write protection for the upper half of the array (addresses 80h-FFh). It offers a page write buffer for up to 16 bytes and is available in an 8-pin SOIC package.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• I²C compatible 2-wire serial interface supporting up to 1 MHz clock frequency
• Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Data logging in industrial systems
• Configuration storage in embedded controllers
• Parameter retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the 8-pin SOIC package and the '-E' temperature grade indicates the Industrial range (-40°C to +85°C). Confirm the specific revision of datasheet DS22102A matches the component batch. Ensure the supply voltage in the target application remains within the 2.5V to 5.5V operational limits specified for the LC variant.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution with high-speed 1 MHz I²C communication is required. It is suitable for designs needing hardware-level protection against accidental writes to critical data segments. Consider the 8-pin SOIC form factor for standard surface-mount assembly processes requiring moderate pin pitch.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit serial EEPROMs. The 'LC' designation distinguishes it from the 'AA' series by offering extended speed capabilities up to 1 MHz at higher voltages. The 'HT' suffix typically denotes tape and reel packaging, while 'SN' specifies the SOIC package type.

Memory IC Replacement Considerations

Direct functional substitutes include the 24LC024HT-I/SN for the same package with a lower temperature range, or the 24LC024HT-E/MC for a DFN package. Cross-referencing with the 24AA024H series requires verifying voltage compatibility as the AA series supports operation down to 1.7V.
