Ethernet Controllers

The 7100A device is an Ethernet controller SoC featuring an "un-attackable" hardware network engine for preventing network attacks such as flooding, spoofing and injection. The device does not have the on-chip microcontroller and needs to be connected to an external host via an SPI serial bus.
