Overview

The 24AA025E48-I/SN is a 2Kbit I2C EEPROM that comes pre-programmed with a globally unique 48-bit node address compatible with EUI-48. This specialized memory chip eliminates the need for manufacturers to purchase and manage their own OUI blocks by providing a factory-programmed MAC address. It operates over a wide voltage range of 1.7V to 5.5V and is AEC-Q100 qualified for automotive reliability.

Why Choose This Part

The primary advantage is the built-in, globally unique 48-bit node address, which saves costs associated with MAC address registration and factory programming. It features robust data integrity with over 200 years of data retention and a high endurance rating of one million erase/write cycles. The low standby current of 1 uA and 1.7V minimum supply voltage make it ideal for battery-powered applications.

Applications

Network Interface Controllers
Provides a globally unique MAC address for Ethernet or Wi-Fi connected devices without manual serialization.
Industrial Automation
Used as a unique hardware identifier in Modbus, CAN bus, or EtherCAT nodes for network discovery.
Automotive Systems
AEC-Q100 qualification makes it suitable for vehicle networking and electronic control unit (ECU) identification.
IoT Prototyping
Simplifies deployment of large-scale IoT fleets by providing unique EUI-48 identifiers out of the box.

Getting Started

To use this device, connect the SCL and SDA pins to an I2C bus with appropriate pull-up resistors and ensure the VCC is between 1.7V and 5.5V. The EUI-48 identifier is located in a read-only block at the top of the memory array; refer to the datasheet for the specific byte addresses. Use standard I2C libraries at clock speeds up to 400 kHz to interface with any microcontroller.
