UDP Network Interface with Ethernet MAC for the M8051W & M8051EW
The UDPMAC also includes Ethernet Media Access Controller (MAC) functionality that is compatible with the RFC894 protocol. The MAC interfaces to an external PHY using the four-wire RGMII gigabit interface. The PHY can be controlled using the UDPMAC via a four-wire MDIO interface.
The integral ARP protocol handler enables the UDPMAC to autonomously identify itself on networks and respond to ARP MAC address requests. The ARP logic includes a single-depth cache suitable for identifying the remote device on a point-to-point connection.
