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 W5200 device does not have the on-chip microcontroller and needs to be connected to an external host via an SPI serial bus.
