10/100/1000 Ethernet MAC DO-254 IP Core

The 10/100/1000 Ethernet MAC Controller DO-254 IP Core implements the Media Access Control as specified in the IEEE 802.3-2008 specification.

It can be configured to interface with the PHY through MII, RMII, GMII or SGMII, giving a wide choice to the user for the selection of the chip to connect to the physical layer. It can be configured to operate at 10 Mbps, 100 Mbps or 1000 Mbps, allowing the user to select the speed in base of their needs such as power, size, latency, etc.

The Ethernet MAC Controller has been developed to DAL A according to the DO-254 / ED-80 and is accompanied by a Certification Kit.

A radiation-hardened version with Triple Modular Redundancy (TMR) is also available.
