Description

The AX88190A provides industrial standard NE2000 registers level compatable instruction set. Various drivers are easy acquired, maintenance and usage with no pain and tears.

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 support 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.

The main difference between AX88190A and AX88190 are : 1) Replace memory I/F with SNI I/F. 2) Fix OE# signal synchronous problem 3) Fix interrupt status can't always clean up problem of AX88190. 4) Add 8 general Purpose I/O ports. 5) Change MPD_SET (pin 74 -> pin 68) and PPD_SET (pin 76  > pin 70) power on setup pins location.

AX88190A use 128-pin LQFP low profile package, typical 25MHz operation, dual 5V and 3.3V CMOS process with 5V I/O tolerance or pure 3.3V operation.
