1.0 Introduction
1.1 General Description:
The AX88196 provides industrial standard NE2000 registers level compatable instruction set. Various
drivers are easy acquired, maintenance and usage. No much additional effort to be paid. Software is easily
port to various embedded system with no pain and tears
The AX88196 Fast Ethernet Controller is a high performance and highly integrated local CPU bus Ethernet
Controller with embedded 8K*16 bit SRAM. The AX88196 supports both 8 bit and 16 bit local CPU
interfaces include MCS-51 series, 80186 series, MC68K series CPU and ISA bus. The AX88196 implements
both 10Mbps and 100Mbps Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard and
supports both 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.
As well as, the chip also provides Standard Print Port ( parallel port interface ), can be used for printer server
device or treat as simple general I/O port.
The main difference between AX88196 and AX88195 are : 1) Replace memory I/F with SNI and SPP I/F. 2)
Canceling SAX address decoding. 3) Fix interrupt status can’t always clean up problem of AX88195.
AX88196 use 128-pin LQFP low profile package, 25MHz operation, dual 5V and 3.3V CMOS process with
5V I/O tolerance or pure 3.3V operation.
