● 高效能Non-PCI介面
● 小筆電
AX88796C SMDK2440評估板提供客戶透過SRAM-Like介面,連接到三星SMDK2440平台(S3C2440A 32-bit ARM MCU)來驗證AX88796C網路晶片功能。客戶也可以透過SRAM-Like介面連接到其他嵌入式系統來進行測試。
Please register MyASIX membership and then download the latest AX88796C datasheet, reference schematic, gerber/PCB layout files and application design note from AX88796C Product web page directly.
You can open the gerber files of AX88796C demo board by running ORACLE's AutoVue Evaluation Revision tool (30 days evaluation date). Please visit ORACLE's web site for more details.
You can open the PowerPCB PCB layout file of AX88796C demo board by running Mentor Graphics PADS Layout Product Evaluation Software (No time limitation but with limited function). Please visit Mentor Graphics' web site for more details.
Yes, please deliver your own AX88796C schematic and PCB layout files to ASIX's Support (support@asix.com.tw) for further review before making your own AX88796C PCB board.
The AX88796C supports total seven different types of bus interfaces include 8/16 Bit SRAM-like bus interface, 8/16-Bit Address-Data Multiplex interface, Renesas CPU series bus interface, MCS-51 and SPI bus interface. The AX88796C can be configured to the specific bus type automatically by pull-up and pull-down the EECS/EECK/I_FULL pins.
The 25MHz crystal signals of AX88796C board should be winthin 25MHz +- 50ppm.
The reference Ethernet transformer on the AX88796C demo board is the Bothhand LU1S041X LF (Turns Ratio 1CT:1CT, Auto-MDIX) single RJ-45 connector module with integrated 10/100 BASE-TX magnetic.
The AX88796C supports 16-bit mode 93C56 or 93C66 EEPROM.
Yes, the AX88796C EEPROM is optional if the MAC address can be stored on the Flash memory of your embedded system. The other EEPROM setting can also be configured by AX88796C registers directly.
Yes, every Ethernet device must have a unique MAC address. Users should always assign a unique MAC address for every AX88796C based devices.
You must first have an OUI or an IAB, to which you then append 24 or 12 bits respectively, in a way that makes the resulting 48-bit number unique, i.e., your 24 or 12 bits must be unique within your organization, which will require coordination among all the users of your organization's OUI or IAB. Please visit the IEEE-SA web site for details.
Yes, AX88796C supports the LED Control Registors (LCR0, LCR1) to control the AX88796C Ethernet LEDs behaviors.
Yes, ASIX provides AX88796C Linux/WinCE/etc. drivers source codes and software programming guide for customer's reference so you can modify the AX88796C driver source code to work on your own target platforms directly.
Please visit the AX88796C Driver Download web page for details.
Please contact ASIX Sales (sales@asix.com.tw) directly.
Yes, AX88796C supports a 8051 MCU uIP TCP/IP stack porting source code for customers' reference.
No, the AX88796C driver source code is different from AX88796B driver source code. Please refer to AX88796C driver source code to implement AX88796C driver on your target platforms directly.
