Product description
The AX88195 Fast Ethernet Controller is a high performance and highly integrated local CPU bus Ethernet Controller.
The AX88195 supports both 8 bit and 16 bit local CPU interfaces include MCS-51 series, 80x86 series, MC68K series
CPU and ISA bus. The AX88195 implements both 10Mbps and 100Mbps Ethernet function based on IEEE802.3 /
IEEE802.3u LAN standard and supports both 10Mbps/100Mbps media-independent interface (MII) to simplify the
design. Two low cost 32k*8 SRAM is required for packet buffer.
