Product description
The AX88790 Fast Ethernet Controller is a high performance and highly integrated PCMCIA bus Ethernet Controller
with embedded 10/100Mbps PHY/Transceiver and 8K*16 bit SRAM. The AX88790 contains a 16 bit PCMCIA
interfaces to host CPU and compliant with PC Card Standard – February 1995. The AX88790 implements both 10Mbps
and 100Mbps Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard. The AX88790 also provides an extra
IEEE802.3u compliant media-independent interface (MII) to support other media applications. Using MII interface,
Home LAN PHY type media can be supported. The AX88790 is built in interface to connect FAX/MODEM chipset with
parallel bus interface.

1.0 Introduction
1.1 General Description:
The AX88790 provides industrial standard NE2000 registers level compatible instruction set. Various drivers are easy
acquired, maintenance and usage with no pain and tears
The AX88790 Fast Ethernet Controller is a high performance and highly integrated PCMCIA bus Ethernet Controller
with embedded 10/100Mbps PHY/Transceiver and 8K*16 bit SRAM. The AX88790 contains a 16 bit PCMCIA
interfaces to host CPU and compliant with PC Card Standard – February 1995. The AX88790 implements both 10Mbps
and 100Mbps Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard. The AX88790 also provides an extra
IEEE802.3u compliant media-independent interface (MII) to support other media applications. Using MII interface,
Home LAN PHY type media can be supported. The AX88790 is also built in interface to connect FAX/MODEM chipset
with parallel bus interface.

The main difference between AX88790 and AX88190 are: 1) Embedded packet buffer memory 2) Built-in 10/100Mbps
PHY/Transceiver 3) Replace memory I/F with PHY/Transceiver I/F. 4) Fix OE# signal synchronous problem 5) Fix
interrupt status can’t always clean up problem of AX88190. 6) Add 3 general-purpose input pins.
AX88790 use 128-pin LQFP low profile package, 25MHz operation, and single 3.3V operation with 5V I/O tolerance.
The ultra low power consumption is an outstanding feature and enlarges the application field. It is suitable for some
power consumption sensitive product like Compact Flash Adapter Card, PDA (Personal Digital Assistant) and Palm size
computer …etc.

DESCRIPTION
79 CMOS Local Clock: Typical a 25Mhz clock, +/- 100 PPM, 40%-60%
duty cycle. The signal not supports 5 Volts tolerance ( See application
note also )
Crystal Oscillator Input: Typical a 25Mhz crystal, +/- 25 PPM can be
connected across XTALIN and XTALOUT.
80 Crystal Oscillator Output: Typical a 25Mhz crystal, +/- 25 PPM can be
connected across XTALIN and XTALOUT. If a single-ended external
clock (LCLK) is connected to XTALIN, the crystal output pin should
be left floating.
44 Clock Output: This clock is source from LCLK/XTALIN.
3 Reset
Reset is active high then place AX88790 into reset mode immediately.
During falling edge the AX88790 loads the power on setting data.
And, after the falling edge the AX88790 loads the EEPROM data.
47, 65 Test Pins : Active high
These pins are just for test mode setting purpose only. Must be pull
down or keep no connection when normal operation.
46 For test only. Must be pulled down at normal operation.
45 For test only. Must be pulled down or keep no connection when normal
operation.
59 FAST_MODE : Active LOW
The pin is just for test mode only. Must be pulled high or keep no
connection when normal operation.
58 EEPROM SIZE = 0: 93C46 type 128 byte EEPROM is used.
EEPROM SIZE = 1: 93C56 type 256 byte EEPROM is used.
92 This sets the common mode voltage for 10Base-T and 100Base-TX
modes. It should be connected to the center tap of the transmit side of
the transformer
