EUI-48™/EUI-64™ MAC Address Chips
Need fast, easy and inexpensive access to MAC addresses?
Microchip’s pre-programmed EUI-48™ MAC address chips
have a unique ID and require no serialization.
These plug-and-play Serial EEPROMs provide low cost easy
access to IEEE MAC addresses eliminating the need for
programming and serialization on the MCU—helping you save
cost and get to market faster. For more information visit
