ASIX Electronics Corp. will showcase its Wi-Fi speaker and Wi-Fi IP camera reference designs based on its newly developed Wi-Fi SoC solution at Embedded Systems Conference in San Jose, March 31-April 2, 2009.

The AX220xx Wi-Fi SoC family provides cost competitive wireless connectivity solution for bridging uncompressed digital audio data, compressed digital video data and serial/parallel user data through its interfaces over the Wi-Fi network. In addition, ASIX will live-demo multimedia streaming video distribution scenario for its two new products: the AX33001, ARM9-based SoC with QoS packet flow engine and security engine; and the AX88782/AX88613, 2/3-port Ethernet switch controller with QoS support. ASIX's USB-to-LAN controller, AX88772/A family, for Nintendo Wii, Apple MacBook Air, UMPC, MID and netbook applications and Non-PCI/SRAM-like embedded Ethernet controller will also be showcased at the booth.

The AX220xx family is a single-chip microcontroller with TCP/IP and 802.11 WLAN MAC/baseband SoC solution offering high performance dual-CPU architecture with 1Mbyte on-chip flash program memory and 96Kbyte data memory for main CPU and Wi-Fi CPU, TCP/IP accelerator, 802.11a/b/g compatible WLAN MAC/baseband, fast Ethernet MAC and versatile peripheral interfaces targeted for wide varieties of applications which need wireless/wired LAN or Internet access. With dedicated Wi-Fi CPU running Wi-Fi protocol suite, the AX220xx family provides simple, easy, small-form-factor chip and module solutions for enabling wireless connectivity for applications such as consumer electronics, networked home appliances, Wi-Fi speaker, industrial equipments, security systems, remote data collection equipments, remote control, remote monitoring and remote management.

The AX33001 is an ARM9-based single-chip Ethernet MCU with QoS packet flow engine and security engine. The AX33001 features a 280MHz ARM926EJ-S CPU core, 16Kbyte I-cache, 16Kbyte D-cache, DDR controller and NAND/NOR flash memory interface. The hardware accelerated QoS packet flow engine supports comprehensive L2-L4 QoS functions and packet forwarding engine, Network Address Translation for IPv4/IPv6 routing and translation and advanced traffic scheduling and shaping on its WAN port. The security engine supports AES/DES/3DES encryption, SHA-1/MD-5 hash and Keyed-Hash Message Authentication Code. The AX33001 also provides wide variety of connectivity interfaces including 2-port 10/100Mbit/s Ethernet MAC with MII/RMII interface, PCI host bridge controller, USB 2.0 host controller and IDE ATA-133 controller. The AX33001 is targeted at applications such as multimedia digital home gateway and server, secure wireless IPv6 networking attach storage (NAS) router among 3G femtocell and WiMAX, Zigbee gateway, IP-enabled POS terminals, USB device server, printer server, NAS and multimedia co-processor for IP camera, video conferencing and DVR.

The AX88782 is a single-chip 2-port 10/100M Ethernet Switch controller featuring a 3-port switching fabric with QoS priority management, three 10/100M MACs, two 10/100M PHYs and 8/16bit SRAM-like host interface. The AX88782 is targeted at performance-sensitive embedded applications needing support of two Ethernet ports, typically one as LAN port and one as WAN port. The AX88782 supports simple SRAM-like host interface, checksum offload engine and burst-mode access making it easy to provide high performance 2-port Ethernet connectivity solution for any embedded MCU. The built-in switching fabric supports non-blocking wire-speed forwarding and four priority queues for advanced QoS functions including Port-Based, 802.1p VLAN, IPv4 TOS and IPv6 COS to prioritize voice, video, audio and data traffic delivery. The AX88782 combines the benefits of high integration and small form factor making it a suitable single-chip solution for designing high performance, QoS-aware and cost effective 2-port Ethernet function for embedded system applications such as VoIP phone/ATA adapters, IP cameras, next-generation IP-STB/IPTV, industrial controller/network sensors, port redundancy/port monitoring and single board computers. For higher performance application, ASIX also offers the AX88783 with 16/32bit host interface as an alternative option.
