1.0 Introduction
1.1 General Description:
The AX88190 provides industrial standard NE2000 registers level compatable instruction set. Various
drivers are easy acquired, maintenance and usage with no pain and tears
The AX88190 Fast Ethernet Controller is a high performance PCMCIA bus Ethernet Controller. The
AX88190 contains a 16 bit PCMCIA interfaces to host CPU and compliant with PC Card Standard –
February 1995. The AX88190 implements both 10Mbps and 100Mbps Ethernet function based on
IEEE802.3 / IEEE802.3u LAN standard. The AX88190 supports 10Mbps/100Mbps media-independent
interface (MII) to simplify the design. The AX88190 is built in interface to connect FAX/MODEM chipset
with parallel bus interface.
AX88190A use 128-pin LQFP low profile package, 25MHz operation frequency, dual 5V and 3.3V CMOS
process with 5V I/O tolerance or pure 3.3V operation.
