Product Summary
The AX88783LF 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 the 8/16/32-bit SRAM-like host interface targeted for embedded system applications that need support of two Ethernet ports, typically one for LAN port and one for WAN port. The AX88783LF supports the simple SRAM-like host interface, the routine packet checksum calculation, and the burst read and write access through host port which make it easy to provide 2-port Ethernet connectivity solutions for any embedded MCU with reasonable performance. The AX88783LF combines the benefits of high integration and flexibility which makes it a ideal single-chip solution for designing high performance, QoS-aware, cost effective and small form factor 2-port Ethernet function for any embedded system applications.
