24AA02E48

The 24AA02E48 is a Microchip 2 Kbit serial electrically erasable PROM that communicates over the two-wire I2C bus, in a small 5-pin package, with a factory-programmed EUI-48 node identity. It stores a small amount of configuration or calibration data, and the factory-set 48-bit EUI-48 address gives a network device a globally unique identity without a separate serial-number chip, which suits a product that must have a unique MAC address on every unit. The device operates from about 1.7 V to 5.5 V, so it works on a low-voltage rail as well as a standard 3.3 V or 5 V rail, and it keeps its data without power for decades, which suits the settings that must survive the life of the product. The small 5-pin package saves the board area, and the I2C interface uses only two pins and shares a bus with other devices, so it is easy to add to a design. The factory EUI-48 is available at the top of the memory, so the host reads the identity and the settings from the same device, and the write-protect feature keeps the data safe. Typical applications include network interface identity, MAC-address storage, serial-number and product-identity storage and small configuration storage. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the device and plan the bus and the layout.
