24LC024H-I/ST

Memory IC Overview

The Microchip Technology 24LC024H-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 2.5V to 5.5V and supports a maximum clock frequency of 1 MHz via a 2-wire I²C compatible interface. The device features Schmitt trigger inputs for noise suppression, output slope control to eliminate ground bounce, and a hardware write protection mechanism that safeguards the upper half of the array (addresses 80h-FFh).

Memory IC Feature Summary

• Hardware write protection for half-array security
• I²C compatible 2-wire serial interface
• Low-power CMOS technology with standby current as low as 1 μA

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial controllers needing parameter retention
• Sensor nodes with limited power budgets

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' against official Microchip documentation to confirm Industrial temperature range (-40°C to +85°C) and TSSOP-8 packaging. Ensure the design accounts for the 2.5V minimum operating voltage, which differs from the broader 24AA024H series. Confirm RoHS compliance status through the manufacturer's latest environmental declarations.

Memory IC Selection Notes

Select this component when an I²C interface is required alongside hardware-level write protection for critical data segments. The 1 MHz clock speed offers higher throughput compared to standard 400 kHz EEPROMs. Verify that the system power rail remains above 2.5V during all operational states to ensure reliable functionality.

Memory IC Part Context

This part belongs to the 24LC024H family of 2 Kbit serial EEPROMs. It shares architectural similarities with the 24AA024H but is distinguished by its 2.5V minimum operating voltage requirement. The 'I' designation indicates industrial temperature grading, while '/ST' specifies the TSSOP surface-mount package type.

Memory IC Replacement Considerations

The 24LC024H-I/MS serves as a pin-compatible alternative in MSOP-8 packaging. For applications requiring lower voltage operation down to 1.7V, the 24AA024H series is functionally similar but requires verification of voltage compatibility.
