EUI-48™/EUI-64™ MAC Address Chips

Need fast, easy and inexpensive access to MAC

addresses? Use pre-programmed MAC address chips

from Microchip. No serialization needed; unique ID.

EUI-48 Programmed Serial EEPROMs provide low cost and easy access

to IEEE MAC Addresses. These plug-and-play devices allow you to quickly

add a MAC address to your networking application eliminating the need for

programming and serialization on the MCU – helping you save cost and get

to market quicker. For more information visit: www.microchip.com/MAC
