简介


AX88796B是一款针对嵌入式及工业以太网应用的低引脚数(LQFP-64) Non-PCI以太网控制芯片。AX88796B采用符合业界标准的8/16位SRAM-like主机接口,可与一般8/16/32位微控制器直接连接,无须任何外部逻辑线路。该组件内建符合IEEE 802.3/ IEEE 802.3u协议的10/100Mbps以太网物理层(PHY)及媒体存取控制器(MAC),整合8K*16位SRAM网络封包缓存器,以高效率的方式进行封包的储存、检索与修改。AX88796广泛支持各项规格包括双绞线正反接线自动校正(HP Auto-MDIX)、网络唤醒、低功耗管理及IEEE 802.3x/ backpressure流量控制。

AX88796B支持两种工作温度范围,包括商业规格0℃~70℃以及工业规格-40℃~85℃。仅64引脚之小型封装可大幅减少所占PCB空间。关于软件的支持,由于AX88796BB与NE2000兼容,在许多嵌入式系统中工程师不需做任何修改即可直接将NE2000驱动程序快速移植到AX88796B上。亚信电子更提供用于8位微控制器的TCP/IP软件堆栈,使AX88796B成为嵌入式应用的最佳以太网解决方案。

    What are the differences between AX88796B, AX88196B and NE2000?
  • What are the differences between AX88796B and AX88796?

    What are the differences between AX88796B and AX88796?
  • What kinds of EEPROM devices are supported by AX88796B?

    The AX88796B supports serial EEPROM device with 16-bit data access, like 93C46 EEPROM (but not 93C56). The EEPROM device is optional for AX88796B.

  • What kinds of CPU interfaces are supported by AX88796B?

    The AX88796B supports both 8-bit and 16-bit CPU interfaces, like MCS-51 (805x) series, 80186 series and ISA bus. ASIX also implements AX88796B under SMDK2440 S3C2440A 32-bit ARM920T core CPU platform successfully.

  • Does the AX88796B support the MC68K CPU interface?

    No, but the AX88796 supports the MC68K CPU interface.

  • How do I reset the MAC by driver?

    1. Read the Reset register (offset 1Fh) to reset MAC.
    (Note: It is READ but not WRITE.)
    2. Wait 1.6ms for reset completion.

  • What is the PHY address of the AX88796B embedded PHY?

    The AX88796B integrates an embedded 10/100M Fast Ethernet PHY. The internal PHY address is 10h.

  • How do I configure a proper duplex mode?

    The AX88796B will auto-configure the MAC duplex mode to match the real duplex mode of embedded PHY so the driver doesn't need to take care about it.

  • How do I configure a proper line speed mode?

    The AX88796B embedded 10/100Mbps PHY/Transceiver will auto-detect a proper line speed so the driver doesn't need to take care about it.

  • How do I configure Interrupt Trigger mode?

    The AX88796B supports both 8-bit and 16-bit local CPU interfaces included MCS-51 series, 80186 series and ISA bus. You shall define the proper Interrupt Trigger mode for the CPU used in bit 4 (IRQ_POL_EEP) and bit 5 (IRQ_TYPE_EEP) of EEPROM offset address 0x02. After hardware reset, AX88796B will auto-load the Interrupt Trigger mode setting from EEPROM into bit 4 and bit 5 of BTCR register. If needed, the driver can also manually set the Interrupt Trigger mode by configuring bit 4 and bit 5 of BTCR register (offset 15h) to overwrite the setting from EEPROM.

  • How do I enable/disable AX88796B interrupt?

    The AX88796B 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 the Flow Control function?

    The AX88796B Flow Control function is disabled by default. You can enable the flow control function in full-duplex mode by setting bit 7 (Flow Control) or the back-presssure function in half-duplex mode by setting bit 6 (Back-pressure) of FCR register (offset 1Ah).

  • How do I enable the WOL function?

    The AX88796B WOL function is disabled by default. You can enable the WOL function by configuring PMR register (Page 3, offset 0Bh) and WUCSR register (Page 3, offset 0Ah).

  • How do I enable the VLAN function?

    The AX88796B VLAN function is disabled by default. You can enable the VLAN function by setting bit 3 (VLANE) of MCR register (offset 1Bh) and configuring VIDR0 register (offset 1Ch) and VIDR1 register (offset 1Dh).

  • How do I enable the TX Queue and TX Buffer Ring functions?

    The AX88796B TX Queue and TX Buffer Ring functions are disabled by default. You can enable the TX Queue and TX Buffer Ring functions by setting bit 5 (TQCE) of MCR register (offset 1Bh) and bit 0 (TBR) of P30D register (Page3, offset 0Dh), respectively.

  • How do I implement the Single and Burst Data Access modes?

    The AX88796B supports two kinds of Data Port for receiving/transmitting packets from/to AX88796B. One is the PIO Data Port (offset 10h); the other one is the SRAM-like Data Port (e.g. offset 800h ~ FFFh for Samsung2440 processor as described in Appendix A4 of AX88796B datasheet). The SRAM-like Data Port address range depends on which address line of host processor is being connected to the address line SA5/FIFO_SEL (pin 45) of AX88796B.

    Software on host CPU can issue Single Data Read/Write command to both PIO Data Port and SRAM-like Data Port. However, to use Burst Data Read/Write commands, one has to use SRAM-like Data Port which requires SA5/FIFO_SEL (pin 45) of AX88796B connecting to an upper address line of host CPU. Our reference schematic have SA5/FIFO_SEL pin connected to upper address line for supporting Burst Data Read/Write commands.

  • Does the AX88796B support the MII interface?

    No, but the AX88196B supports the MII interface. Please refer to AX88196B product web page for more details.

  • How do I get the AX88796B Software Programming Guide?

    Please contact ASIX Sales (sales@asix.com.tw) directly.
