24AA024H-I/MS

Memory IC Overview

The Microchip Technology 24AA024H-I/MS is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz in the Industrial temperature range (-40°C to +85°C). The device supports page writes of up to 16 bytes and includes hardware write protection for the upper half of the memory array via the WP pin.

Memory IC Feature Summary

• Hardware write protection enables locking of the upper half of the memory array (addresses 80h-FFh) by connecting the WP pin to VCC.

Memory IC Applications

• Low-power sensor nodes requiring minimal standby current
• Industrial controllers needing reliable non-volatile data storage
• Systems utilizing multiple devices on a shared I²C bus

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet lists MSOP among several options. Confirm the 'I' designation aligns with the intended industrial operating temperature range. Ensure the component meets RoHS compliance standards if required by your manufacturing specifications.

Memory IC Selection Notes

Select this part when a wide voltage range starting at 1.7V is necessary, distinguishing it from standard 2.5V minimum variants. The 400 kHz speed limit applies specifically to the Industrial grade; higher speeds are reserved for other series members. Consider the half-array write protection feature if security against accidental overwrites is critical.

Memory IC Part Context

This component belongs to the 24AA024H/24LC024H family of 2Kb Serial Electrically Erasable PROMs. The 'H' suffix indicates support for operation down to 1.7V. The 'I' suffix denotes the Industrial temperature rating, while the 'MS' suffix specifies the 8-pin MSOP package format.

Memory IC Replacement Considerations

The 24LC024H-I/MS is a functional substitute within the same family but requires a minimum supply voltage of 2.5V instead of 1.7V. Verify that the system power rails remain above 2.5V during all operational states before substituting.
