24AA024H-I/SN

Memory IC Overview

The Microchip Technology 24AA024H-I/SN is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and supports I²C bus communication with clock frequencies up to 400 kHz. The device features low-power CMOS technology, offering maximum active current of 400 μA and standby current of 1 μA. It includes hardware write protection for the upper half of the array and is housed in an 8-pin SOIC package.

Memory IC Feature Summary

• Hardware write protection capability that locks the upper half of the memory array when the WP pin is tied high
• Low-power design optimized for battery-operated systems with minimal active and standby current consumption
• Integrated Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce

Memory IC Applications

• Battery-powered sensor nodes requiring extended data retention
• Industrial controllers needing reliable non-volatile storage
• Embedded systems utilizing multiple devices on a shared I²C bus

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range of -40°C to +85°C. Confirm the 'SN' designation matches the required 8-lead SOIC package dimensions. Ensure the source documentation explicitly lists this part number as RoHS compliant and lead-free before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when operation below 2.5V is required, distinguishing it from standard 24LC variants. The 'H' series provides a wider voltage range down to 1.7V compared to standard models. Verify that the 400 kHz speed meets system timing requirements and that the 16-byte page buffer aligns with write efficiency needs.

Memory IC Part Context

This device belongs to the 24AA024H/24LC024H family of 2 Kbit serial EEPROMs. It shares architectural similarities with other members but is distinguished by its wide voltage operation starting at 1.7V. The 'I' suffix denotes industrial temperature performance, while the 'SN' suffix specifies the surface-mount SOIC package type.

Memory IC Replacement Considerations

The 24LC024H-I/SN serves as a functional substitute if the application voltage does not drop below 2.5V.
