Microchip AT7910E - SpW-10X SpaceWire router

The SpW-10X routing switch capable of connecting many nodes and routing packets between the nodes connected to it. It is comprised of eight SpaceWire link interfaces and a routing matrix. Its routing matrix enables packets arriving at one link interface to be transferred to and sent out of another link interface on the routing switch. It is manufactured using the SEU hardened cell library from Microchip MH1RT CMOS 0.35-µm rad-hardened sea of gates technology.
