24AA02E64T-E/SN

Memory IC Overview

The Microchip Technology 24AA02E64T-E/SN is a 2 Kbit Electrically Erasable PROM organized as two blocks of 128 x 8-bit memory. It features a 2-wire I2C compatible serial interface with a maximum clock frequency of 400 kHz (100 kHz below 2.5V). The device operates on a single supply ranging from 1.7V to 5.5V and includes a pre-programmed, globally unique 64-bit EUI-64 node address stored in the upper half of the array. It utilizes low-power CMOS technology with standby currents of up to 5 µA at extended temperatures.

Memory IC Feature Summary

• Factory programmed with a globally unique 64-bit EUI-64 node address for direct system identification
• Low-voltage operation down to 1.7V with Schmitt trigger inputs for noise suppression
• Supports page write operations with an 8-byte buffer to enhance bus throughput
• Includes output slope control to eliminate ground bounce during switching

Memory IC Applications

• Network node identification in embedded systems requiring unique hardware addresses
• I2C bus devices needing permanent factory programming for traceability
• Low-power portable electronics operating on minimal voltage supplies
• Industrial applications requiring data retention over extended temperature ranges

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the presence of the EUI-64 identifier in the datasheet or product selection guide, as other variants in this family may contain EUI-48 addresses or no pre-programmed identity. Ensure the component meets RoHS compliance requirements for your manufacturing process.

Memory IC Selection Notes

Select this part when a unique 64-bit IEEE address is required directly within the EEPROM structure. Compare against EUI-48 variants if only 48-bit identifiers are needed. Consider the 8-byte page size limitation for write operations versus larger buffers in higher capacity devices. Verify that the 400 kHz clock speed aligns with the master controller's capabilities at the target supply voltage.

Memory IC Part Context

This component belongs to the 24AA02XEXX series of 2 Kbit Serial EEPROMs designed for I2C communication. It shares the same physical footprint and electrical characteristics as the 24AA02E48 variant, differing primarily in the length of the pre-programmed node address. The series supports both industrial and automotive temperature grades.

Memory IC Replacement Considerations

The 24AA02E48 serves as a functional substitute if the application requires a 48-bit EUI address instead of 64-bit. Other 24AA02 series parts without pre-programmed addresses can replace this unit if unique identification is not necessary.
