24AA512-I/MF

Memory IC Overview

The Microchip Technology 24AA512-I/MF is a 512 Kbit Electrically Erasable PROM organized as 64K x 8-bit memory. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device features low-power CMOS technology, drawing a maximum read current of 400 µA and standby current of 1 µA. It supports I²C compatible two-wire serial interface, includes Schmitt trigger inputs for noise suppression, and offers hardware write protection via the WP pin.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using functional address lines A0, A1, and A2.
• Includes a 128-byte page write buffer to facilitate efficient data storage operations.
• Features hardware write-protect capability controlled by the WP pin to inhibit array writes.

Memory IC Applications

• Personal communications systems requiring non-volatile data retention
• Data acquisition applications needing low-power operation
• Industrial control systems utilizing I²C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix 'MF' corresponds to the 8-Lead SOIJ package type as specified in the datasheet. Confirm the temperature grade 'I' indicates an industrial range of -40°C to +85°C. Ensure compatibility with the 1.7V to 5.5V operating voltage range required for the 24AA512 series.

Memory IC Selection Notes

Select this component when a 512 Kbit EEPROM with I²C interface is required. Choose the 24AA512 variant specifically for its 1.7V minimum operating voltage capability compared to other series members. Consider the 8-Lead SOIJ package if space-constrained surface mount assembly is necessary.

Memory IC Part Context

This part belongs to the 24XX512 family, which includes the 24LC512 and 24FC512 variants. While sharing similar memory organization and interface protocols, the 24AA512 is distinguished by its lower minimum supply voltage requirement of 1.7V. The family supports both random and sequential reads across the entire memory boundary.

Memory IC Replacement Considerations

The 24LC512 and 24FC512 are functionally similar within the same family but differ in voltage ranges and clock speeds. Verify specific electrical characteristics against the original design requirements before substitution.
