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. 1.2 AX88196 Block Diagram: SMDC SMDIO EECS EECK EEDI EEDO SPP / GIO 8K* 16 SRAM and Memory Arbiter SEEPROM I/F NE2000 Registers STA SNI I/F Remote DMA FIFOs MAC Core MII I/F Print Port or General I/O Host Interface Ctl BUS Fig - 1 AX88196 Block Diagram SA[9:0] SD[15:0] 4 ASIX ELECTRONICS CORPORATION AX88196 Local CPU BUS MAC Controller 1.3 AX88196 Pin Connection Diagram The AX88196 is housed in the 128-pin plastic light quad flat pack.

I O I/O OD Input Output Input/Output Open Drain PU PD P Pull Up Pull Down Power Pin 2.1 Local CPU Bus Interface Signals Group SIGNAL SAL[2:0] TYPE I/PD PIN NO. 113 – 111 DESCRIPTION System Address Select Low : Signals SAL[2:0] are additional address signal input lines which active low enable higher I/O address decoder on chip. System Address Select High : Signals SAH[2:0] are additional address signal input lines which active high enable higher I/O address decoder on chip. System Address : Signals SA[9:0] are address bus input lines which lower I/O spaces on chip.

SNI (Serial Network Interface) has bug for HomePNA application. Solution: Using MII interface for HomePNA solution. Refer to “Demonstration Circuit” on page 37 to 41. 2. SPP (Standard Printer Port) is fail on 186 and 68K modes. Because of can't read out correct information of x19h status port. Solution: This version do not support SPP function on the two modes. If user want to use general purpose port for reading external status. Please using x18h data port to replaces it. 3. SPP command port readback value is from internal registers instead of external pins Solution: ASIX will not fix the problem at this moment. Care must be taken when doing the external pins diagnostic. 4. DTACK can’t fit 68K CPU timing in 68K mode Solution : Using the DTACK automatic insertion function in 68K CPU. 37 ASIX ELECTRONICS CORPORATION AX88196 10/100BASE Fast Ethernet MAC Controller Demonstration Circuit : AX88196 + Ethernet PHY + HomePNA 1M8 PHY AX88196 L 10BASE-T/100BASE-TX & 1M HomePNA ISA1 GND RESET 5V C2 0.1u C1 + 47u/16v B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 B13 B14 B15 B16 B17 B18 B19 B20 B21 B22 B23 B24 B25 B26 B27 B28 B29 B30 B31 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 D16 D17 D18 GND RESDRV +5V IRQ -5V DRQ -12V NOWS# +12V GND SMWTC# SMRDC LOWC# LORC# DAK# DRQ DAK# DRQ REFRSH# BCLK IRQ IRQ IRQ IRQ IRQ DAK# T/C BALE +5V OSC GND M16# IO16# IRQ IRQ IRQ IRQ IRQ DAK# DRQ DAK# DRQ DAK# DRQ DAK# DRQ +5V MASTER16# GND ISA VCC U2 3.3V C8 0.1u C9 + 47u/16v 4 OUT IN OUT ADJ/GND 3 2 1 5V 3.3V GND C10 0.1u C11 + 47u/16v IOCHK# D D D D D D D D CHRDY AEN SA SA SA SA SA SA SA SA SA SA
