The AX88180 is a high-performance and cost-effective non-PCI Gigabit Ethernet controller for various embedded systems including consumer electronics and home network markets that require a higher bandwidth of network connectivity. The AX88180 supports 16/32-bit SRAM-like interface and Gigabit Ethernet MAC, which is IEEE802.3 10Base-T, IEEE802.3u 100Base-T and IEEE802.3ab 1000Base-T compatible. The AX88180 supports full-duplex or half-duplex operation at 10/100/1000Mbps speed with auto-negotiation or manual setting. The AX88180 integrates embedded SRAM for packet buffering to accommodate high bandwidth applications and supports IP/TCP/UDP checksum in hardware to offload processing loading from microprocessor/microcontroller in an embedded system.

How to open the Protel PCB layout file of AX88180 SMDK2440 demo board?
You can open the Protel PCB layout file of AX88180 SMDK2440 demo board by running ORACLE's AutoVue Evaluation Revision tool (30 days evaluation date). Please visit ORACLE's web site for more details.
-
What drivers are available for the AX88180?
The AX88180 supports the following drivers platforms,
1. Windows CE 5.0 BSP driver
2. Linux kernel 2.4.x/2.6.x driver and Uboot driver
Furthurmore, ASIX can provide AX88180 Linux driver source code and the Software Programming Guide for customers who need to develop AX88180 driver on some other platforms. Please contact ASIX Sales (sales@asix.com.tw) for more details. -
Does the AX88180 need an EEPROM device?
The AX88180 supports serial EEPROM device with 16-bit data access, like 93C56 EEPROM. The EEPROM device is optional for the AX88180. AX88180 will auto-load data from the EEPROM device after a hardware reset.
-
How do I reset the external PHY by driver?
1. Write bit 15 (PHY_RESET) of BMCR register to software reset the external PHY.
2. Read the BMCR register to check if the PHY_RESET bit has been self-cleared after the external PHY is reset completely. -
How do I enable/disable AX88180 interrupt?
The AX88180 uses IMR register to enable/disable the interrupt function. The interrupt function can be enabled by setting a non-zero value into IMR register and can be disabled by setting a zero value into IMR register.
-
How do I enable/disable TX/RX Flow Control function?
The AX88180 supports the TX/RX flow control function for 10/100M Full-duplex modes. The users shall configure below registers to enable TX/RX flow control function.
1. Set bit 12 (RXFLOW_EN) of MAC_CFG0 register.
2. Set bit 0 and bit 8 of RX_CFG register.
3. Set bit 5 and bit 6 of MAC_CFG1 register. -
How do I enable/disable the Jumbo frame function?
The AX88180 supports max 15K bytes RX Jumbo frame size and max 4K bytes TX Jumbo frame size. The driver can configure bit 11 (RXJUMBO) and bit 7-10 (RX Jumbo Size) of MAC_CFG1 register to enable/disable RX Jumbo frame function and set the max RX Jumbo frame size. To enable the TX Jumbo frame function, the driver needs to be configured to a max 4095 bytes packet length into the TX_CMD and TXDESx registers and then AX88180 will assign the TXDESx and TXDES(x+1) TX descriptors for this Jumbo packet. Therefore the driver should use the TXDES(x+2) and TXDES(x+3) TX descriptors for next Jumbo packet.
-
How do I read/write the MII PHY Registers?
The AX88180 provides MDIOCTRL and MDIODP registers to access MII PHY registers.
-
How do I enable/disable the back-pressure function?
AX88180 supports the Back Pressure function for 10/100M Half-duplex modes.Configure the following registers to enable Back Pressure function:
1. Set bit 12 (RXFLOW_EN) of MAC_CFG0 register.
2. Set bit 0 and bit 8 of RX_CFG register.
3. Set bit 5 of MAC_CFG1 register.
4. Write 0164h to MAC_CFG2 register to configure Jam Limit value. -
