24LC024HT-I/ST

Memory IC Overview

The Microchip Technology 24LC024HT-I/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 2.5 V to 5.5 V and supports a maximum clock frequency of 1 MHz via an I²C compatible 2-wire serial interface. The device features hardware write protection for the upper half of the array, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce. It is housed in an 8-pin TSSOP package.

Memory IC Feature Summary

• Supports high-speed 1 MHz operation with page write buffer capability for up to 16 bytes.
• Includes hardware write protection that secures the upper half of the memory array when the WP pin is tied high.
• Features Schmitt trigger inputs and output slope control to suppress noise spikes and prevent ground bounce.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Industrial equipment needing reliable data retention

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' corresponds to the Industrial temperature range (-40°C to +85°C) and TSSOP-8 packaging. Confirm RoHS compliance status as required by project specifications. Ensure the ordering quantity matches the manufacturer's standard packing configuration to avoid handling discrepancies during assembly.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM with 1 MHz bus speed is required within the 2.5 V to 5.5 V operating range. It is suitable for designs needing hardware write protection for critical data segments. Consider alternative packages like MSOP or TDFN if board space constraints differ from the TSSOP footprint requirements.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit Serial EEPROMs. The 'LC' designation indicates support for higher clock frequencies compared to the 'AA' variant. The 'I' suffix denotes the industrial temperature grade, while 'ST' specifies the thin-shrink small-outline package type used for surface-mount applications.

Memory IC Replacement Considerations

Direct replacements include other 24LC024 variants with identical electrical characteristics but different packages, such as 24LC024-I/MS or 24LC024-I/P. Cross-brand equivalents must be verified against the 1 MHz speed and 2.5 V minimum voltage requirements.
