AsiaInfo Announces Embedded Wi-Fi System Single Chip AX220xx

2011 China's Most Influential International IC Symposium & Exhibition (IIC-China) is coming soon, AsiaInfo Electronics, which specializes in embedded network chip design, will lead you to take advantage of the newly launched embedded Wi-Fi system. Chip AX220xx, to build a high-quality audio and video digital home applications. Through the "Wi-Fi Wireless Speaker" reference design, system developers can quickly develop wireless LAN audio transmission and receiving devices, and this reference design will be displayed live on the spot. At the same time, AsiaInfo Electronics will also showcase a variety of networking solutions, including: "Low-Power High-Speed ​​USB 2.0 to 10/100M Fast for Universal Applications such as Nintendo Wii, Apple MacBook Air, HP Envy 13, UMPC, MID, and Netbook." Ethernet controllers, "low-power SPI or Non-PCI Ethernet controllers" and other products. Interested parties may wish to visit the Shenzhen Convention & Exhibition Center's AsiaInfo booth 2D27 during the exhibition from February 24th to 26th, 2011. In addition, the General Assembly has a technology sharing area near the Taiwan Area of ​​Hall 2 and Associate Summer Food of AsiaInfo Electronics Market will be speaking from 15:00 to 15:20 on February 24th. "Single Chip Development Trends" is also welcome to listen to.

AsiaInfo Electronics stated that with the gradual maturity of broadband infrastructure and the rapid development of digital home products, many new technologies and networking applications have been introduced that incorporate smart phones. For example, using the built-in Wi-Fi of a smartphone to remotely control various embedded devices, it is only necessary to use virtual buttons on the touch screen, not only as a TV remote controller, to perform situational lighting control, but also to play remote-controlled helicopters, or even Driving a Formula 1 car is not a problem. In addition, Networked Audio technology allows users to use the built-in Wi-Fi of their smartphones in various spaces in the home to conduct various lifestyle applications such as wireless transmission of music. For example, using the convenience of Wi-Fi wireless speakers to listen to online music Or Internet radio, etc., enjoy the music world and create a personalized music environment. In response to this market trend, the "AX220xx Wi-Fi Wireless Speaker" reference design exhibited by AsiaInfo Electronics utilizes the simple, easy-to-use, free software "Remote" on the Apple App store to allow iPhone, iPod Touch and iPad to be used with any device. The iTunes-equipped PC, through the Wi-Fi connection, allows the iPhone to be transformed into a remote control at home to remotely control the order in which iTunes is played on the PC, eliminating the user's inconvenience of manually adjusting the playback sequence before reaching the PC.

The AX220xx provides a high-performance dual-CPU core and 1MB of shared flash memory for program storage, 64KB of data memory for the main processor (MCPU) and 32KB of data memory for the Wi-Fi processor (WCPU), built-in TCP/ IP accelerators, 802.11a/b/g compliant MAC/baseband processors, Fast Ethernet MACs, and a wealth of communications peripherals are available for all types of devices that require access to wired/wireless LANs or the Internet. AX220xx single-chip Wi-Fi microprocessor provides various interfaces for embedded wireless networking applications to enable terminal devices such as industrial control or consumer electronics to connect wirelessly via Wi-Fi. The main applications are roughly divided into the following four categories:

- Intelligent wireless network card: The embedded processor can use the Local Bus, MII/RMII, UART or SPI interfaces to wirelessly access the Internet through the AX220xx Wi-Fi module.

- Serial interface to Wi-Fi bridge: Embedded system with RS-232/422/485, SPI, GPIO, 1-wire or I2C interface, all wireless or Ethernet via AX220xx Wi-Fi module Way for network communication.

- Ethernet-to-Wi-Fi bridge: An embedded system with an Ethernet interface that supports wireless Internet access through the AX220xx Wi-Fi module.

- Wi-Fi wireless speaker: Use the AX220xx's I2S/PCM interface to connect Audio Codec. With built-in or external stereo speakers, you can receive music from your PC via Wi-Fi wireless or Ethernet. You can also use the “Remote” software on iPhone, iPod Touch, and iPad to wirelessly control iTunes on your PC, allowing you to play songs at will.
