Product description
The AX88790 Fast Ethernet Controller is a high performance and highly integrated PCMCIA bus Ethernet Controller
with embedded 10/100Mbps PHY/Transceiver and 8K*16 bit SRAM. The AX88790 contains a 16 bit PCMCIA
interfaces to host CPU and compliant with PC Card Standard – February 1995. The AX88790 implements both 10Mbps
and 100Mbps Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard. The AX88790 also provides an extra
IEEE802.3u compliant media-independent interface (MII) to support other media applications. Using MII interface,
Home LAN PHY type media can be supported. The AX88790 is built in interface to connect FAX/MODEM chipset with
parallel bus interface.
