Features

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
