General Description:

● The AX88140A Fast Ethernet Controller is a high performance and highly integrated PCI Bus Ethernet Controller chip.
● The AX88140A is cost effective, high performance solution for PCI add-in adapters, PC motherboards, or bridge/hub applications.
● It implements both 10Mbps and 100Mbps Ethernet function based on IEEE802.3 LAN standard.
● The AX88140A contains a high speed 32 bit PCI Bus master interface to host CPU. Two large independent transmit and receive FIFO allow the AX88140A to buffer the Ethernet packet efficiently.
● The 10/100Mbps ports can be programmed to support 10Mbps, 100Mbps media- independent interface (MII), or 100BASE-TX physical coding sub-layer (PCS)mode, For 10Mbps operation AX88140A provides a standard serial Interface to the external 10Mbps ENDEC chip.
