Product Description
The AX88782/AX88783 is a non-PCI 2-port 10/100M Ethernet controller with an integrated 3-port switching fabric, three
10/100M MACs, two 10/100M PHYs, and an 8/16/32-bit SRAM-like host interface. This controller is targeted at
embedded system applications that need to support two Ethernet ports, typically one for a LAN port and one for a WAN
port. The AX88782/AX88783 supports simple a SRAM-like host interface, routine packet checksum calculation, and
burst-mode access which make it easy to provide high performance 2-port Ethernet connectivity solutions for any
embedded MCU. The built-in switching fabric supports non-blocking wire-speed forwarding and provides four priority
