24AA024HT-I/MS

Memory IC Overview

The Microchip Technology 24AA024HT-I/MS is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.7 V to 5.5 V and supports a maximum clock frequency of 400 kHz via a 2-wire I²C compatible interface. The device features hardware write protection for the upper half of the array, low-power CMOS technology with standby current under 1 μA, 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
• Low-power design ensures minimal active and standby current consumption
• Schmitt trigger inputs provide noise suppression for reliable data transmission

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Calibration parameter retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape and reel packaging as specified by the manufacturer. Confirm the 'I' designation indicates the industrial temperature grade (-40°C to +85°C). Ensure the MSOP package matches the target footprint requirements. Cross-reference the specific datasheet revision to confirm pinout compatibility.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM is required with a wide 1.7 V to 5.5 V operating voltage range. It is suitable for applications needing hardware write protection for critical data segments. Choose this part over the LC variant if operation below 2.5 V is necessary or if 400 kHz bus speed suffices. Verify that the MSOP package fits the available board space.

Memory IC Part Context

This device belongs to the 24AA024H/24LC024H family of 2 Kbit serial EEPROMs. It shares architectural similarities with other members of the series but is distinguished by its specific voltage range and interface speed capabilities. The MSOP package provides a compact surface-mount solution for space-constrained designs requiring non-volatile memory storage.

Memory IC FAQ

How does the WP pin function?

Tying the WP pin to VCC enables hardware write protection for the upper half of the array (addresses 80h-FFh), while tying it to VSS allows write access to all locations.

What is the page write buffer size?

The device includes a page write buffer capable of storing up to 16 bytes of data before initiating an internal write cycle.
