The AX88190A Fast Ethernet Controller is a high performance and highly integrated PCMCIA bus Ethernet Controller with embedded 8K*16 bit SRAM. The AX88190A contains a 16 bit PCMCIA interfaces to host CPU and compliant with PC Card Standard February 1995. The AX88190A implements both 10Mbps and 100Mbps Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard. The AX88190A supports 10Mbps/100Mbps media-independent interface (MII) and legacy pure 10Mbps SNI interface to simplify the design. Using Serial Network Interface (SNI) transceiver, Home LAN PHY or 10BASE-2 BNC type media can be supported. The AX88190A is built in interface to connect FAX/MODEM chipset with parallel bus interface.
