24AA024H-I/ST

Memory IC Overview

The 24AA024H-I/ST is a 2 Kbit (256 x 8) serial electrically erasable PROM manufactured by Microchip Technology. It operates on a single supply voltage ranging from 1.7V to 5.5V and features a 2-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, drawing a maximum active current of 400 μA and a standby current of 1 μA. It includes hardware write protection for the upper half of the array and supports page writes of up to 16 bytes. The component is housed in an 8-pin TSSOP package and is rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper memory half via the WP pin.
• Low-power design ensures minimal active and standby current consumption.
• I2C compatibility allows connection of up to eight devices on a single bus.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Sensor nodes with limited power availability
• Embedded systems utilizing I2C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature range and package type. Confirm RoHS compliance status through official manufacturer documentation. Ensure the specific variant aligns with the intended voltage and interface requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a wide voltage range starting at 1.7V is necessary for low-power applications. The Industrial temperature rating suits environments outside standard commercial limits. Verify that the 400 kHz speed meets system timing constraints.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit Serial EEPROMs. The 'I' suffix indicates an Industrial temperature grade, while 'ST' denotes the 8-lead Thin Shrink Small Outline Package. It serves as a non-volatile memory solution for microcontroller-based designs.

Memory IC Replacement Considerations

The 24LC024H-I/ST is a functional substitute within the same series, though it requires a minimum supply voltage of 2.5V compared to the 1.7V minimum of the 24AA024H.
