24AA024HT-I/ST

Memory IC Overview

The Microchip Technology 24AA024HT-I/ST is a 2 Kbit (256 x 8) serial electrically erasable PROM. It operates on a single supply voltage ranging from 1.7V to 5.5V and utilizes a 2-wire I²C compatible interface. The device supports clock frequencies of up to 400 kHz, with a maximum active current of 400 μA and standby current of 1 μA. It features hardware write protection for half the array, a page write buffer for up to 16 bytes, and an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Integrated Schmitt trigger inputs and noise filters provide enhanced signal integrity on noisy bus environments.
• Page write capability allows efficient data transfer by buffering up to 16 bytes before internal programming.
• Low-power CMOS technology ensures minimal active and standby current consumption during operation.

Memory IC Applications

• Data logging in battery-powered sensor nodes
• Configuration storage for microcontroller systems
• Calibration parameter retention in industrial instrumentation

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the '/ST' suffix indicates the TSSOP-8 package type. Ensure the specific variant matches the required voltage and speed specifications for the target application environment.

Memory IC Selection Notes

Select this component when a low-voltage EEPROM with hardware write protection is required. The 24AA024H series is suitable for applications needing compact memory solutions with robust noise immunity. Consider the page write buffer size and available address lines for system integration planning.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit Serial EEPROMs. The 'H' designation typically denotes high-speed or enhanced features compared to standard variants. The 'I' suffix specifies the industrial temperature grade, distinguishing it from automotive or extended temperature options within the same product line.

Memory IC Replacement Considerations

Direct substitutes include other 24AA024H variants with matching package and temperature ratings. Verify compatibility regarding voltage ranges and interface speeds when considering cross-brand alternatives.
