24AA02E48-E/SN

Memory IC Overview

The Microchip Technology 24AA02E48-E/SN is a 2 Kbit serial EEPROM featuring a pre-programmed, globally unique 48-bit EUI-48 node address. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports I2C compatible 2-wire serial interfaces with clock frequencies up to 400 kHz at VCC ≥ 2.5V. The device utilizes an 8-lead SOIC package and is rated for extended industrial temperature ranges from -40°C to +125°C.

Memory IC Feature Summary

• Factory-programmed globally unique 48-bit IEEE EUI-48 node address permanently stored in the upper half of the memory array
• Low-power CMOS technology enabling operation down to 1.7V with minimal standby current consumption
• Integrated noise protection via Schmitt trigger inputs and output slope control to eliminate ground bounce
• Hardware write protection for the upper memory half containing the node address while allowing full access to user data

Memory IC Applications

• IoT device identity authentication and secure boot processes
• Firmware binding and anti-counterfeiting systems
• Network node identification in I2C bus architectures
• Asset tracking and lifecycle management modules

Memory IC Procurement Notes

Verify that the ordering suffix matches the required specifications: 'E' indicates the extended temperature range (-40°C to +125°C), and '/SN' denotes the 8-lead SOIC package. Confirm the specific revision level against the manufacturer's datasheet DS20002124H to ensure compatibility with your system design requirements.

Memory IC Selection Notes

Select this component when a permanent hardware identifier is required for security or tracking purposes. The E variant is necessary for environments exceeding standard industrial temperatures. Ensure the application logic accounts for the fixed I2C addressing structure where chip select pins are not utilized for this specific model.

Memory IC Part Context

This part belongs to the 24AA02XEXX family of 2 Kbit serial EEPROMs designed specifically for applications requiring unique device identification. Unlike standard EEPROMs, these devices integrate non-volatile memory with factory-burned IEEE addresses, simplifying system integration for networked devices without requiring external identification components.

Memory IC Replacement Considerations

Direct replacements include other members of the 24AA02XEXX family such as the 24AA02E64-E/SN for EUI-64 support, or the 24AA025E48-E/SN if cascading capabilities are needed. Verify package compatibility and temperature ratings before substitution.
