24AA512T-I/MF

Memory IC Overview

The Microchip Technology 24AA512T-I/MF is a 512 Kbit (64K x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device supports page writes up to 128 bytes and includes hardware write protection via the WP pin. It is housed in an 8-lead UDFN package, rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on a single bus using hardware address inputs A0, A1, and A2.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Features self-timed erase/write cycles with automatic acknowledge polling capability.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation

Memory IC Procurement Notes

Verify that the suffix 'MF' corresponds to the 8-lead UDFN package type as specified in the datasheet. Confirm the temperature grade 'I' matches the required -40°C to +85°C operating range. Ensure the logic level compatibility aligns with the system's VCC supply voltage.

Memory IC Selection Notes

Select this component for applications requiring low-power operation down to 1.7V. The 400 kHz clock speed is suitable for standard I²C buses. Consider the 128-byte page buffer for efficient data writing. Verify that the UDFN package dimensions fit the available PCB space.

Memory IC Part Context

This part belongs to the 24XX512 family of serial EEPROMs, which also includes the 24LC512 and 24FC512 variants. While sharing similar interfaces and capacities, these variants differ in minimum operating voltage and maximum clock frequency specifications.
