24AA025E64T-I/SN

Memory IC Overview

The Microchip Technology 24AA025E64T-I/SN is a 2 Kbit Electrically Erasable PROM organized as two blocks of 128 x 8-bit memory. It features a 2-wire serial interface compatible with I2C, supporting clock frequencies up to 400 kHz (100 kHz below 2.5V). The device operates on a single supply ranging from 1.7V to 5.5V and includes a 16-byte page write buffer. Factory programming provides a globally unique, pre-programmed 64-bit EUI-64 node address stored in the upper half of the array.

Memory IC Feature Summary

• Pre-programmed with a globally unique 64-bit EUI-64 node address for system identification
• Supports 16-byte page write operations for efficient data storage
• Includes Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• System identification and tracking using IEEE EUI-64 standards
• Low-voltage embedded systems requiring non-volatile memory
• I2C bus networks requiring unique node addressing

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the 8-lead SOIC package and 'T' indicates tape and reel packaging. Confirm the temperature grade 'I' matches industrial requirements (-40°C to +85°C). Ensure the specific 'E64' variant is selected for EUI-64 compatibility rather than EUI-48.

Memory IC Selection Notes

Select this component when a unique hardware identifier is required alongside standard EEPROM functionality. The 24AA025E64 offers a larger 16-byte page buffer compared to the 8-byte buffer in the 24AA02E64. Verify voltage levels, as clock frequency drops to 100 kHz if VCC is below 2.5V.

Memory IC Part Context

This part belongs to the 24AA02XEXX family of 2 Kbit serial EEPROMs. It shares electrical characteristics with the 24AA02E48, 24AA025E48, and 24AA02E64 models. The primary distinction lies in the pre-programmed node address format (EUI-48 vs. EUI-64) and the page write buffer size (8 bytes vs. 16 bytes).

Memory IC Replacement Considerations

The 24AA02E64T-I/SN serves as a direct substitute if an 8-byte page buffer and EUI-64 addressing are sufficient. For EUI-48 applications, the 24AA025E48T-I/SN or 24AA02E48T-I/SN may be used depending on buffer size requirements.
