 AX22001 -- Single Chip Microcontroller with TCP/IP and 802.11 WLAN MAC/Baseband (32GPIOs, LQFP-128) New!

AX22001, Single Chip Micro-controller with TCP/IP and 802.11 WLAN MAC/Baseband, is a System-on-Chip (SoC) solution which offers high performance dual-CPU architecture with on-chip 1MB shared Flash as Program Memory, on-chip 64KB Data Memory for Main CPU (MCPU), on-chip 32KB Data Memory for Wi-Fi CPU (WCPU), TCP/IP accelerator, 802.11a/b/g compatible WLAN MAC/Baseband, Fast Ethernet MAC, and rich communication peripherals for wide varieties of application which need access to the wired/wireless LAN or Internet.

The dual-CPU architecture of AX22001 utilizes the MCPU for applications and TCP/IP processing, and the WCPU for WLAN protocol processing and Ethernet to WLAN packet format translation. The built-in WLAN MAC and Baseband processor are compatible with IEEE 802.11a/b/g standard, and support security features compatible with 802.11i and QoS features compatible with IEEE 802.11e, and support operation in Infrastructure, Simple AP or Ad-Hoc (IBSS) network topology.

In addition to standalone application, AX22001 with TCP/IP protocol suite running on-chip and various parallel and serial host interfaces supported, such as Local Bus Interface, High Speed UART or High Speed SPI, can be used as a network co-processor to offload TCP/IP and WLAN protocol processing loading from system CPU in an embedded system.

AX22001 provides cost effective wire or wireless networking solution to enable simple, easy, and low cost Internet connection capability for many applications, such as consumer electronics, networked home appliances, industrial equipments, security systems, remote data collection equipments, remote control, remote monitoring, and remote management.

 FAQs

click here for more AX22001 FAQs....
Q0001: How can I start to implement AX220xx applications?
A0001: ASIX provides plenty of AX220xx technical documents and sample codes for customers' reference. User can purchase an AX220xx reference design board and refer to the provided reference design source code as baseline to implement your own AX220xx applications. Please contact ASIX Sales staffs at sales@asix.com.tw for more details.

If user would like to implement AX220xx family on your application directly without having to buy the AX220xx reference design board, you should contact ASIX Sales staffs to get AX220xx related technical documents and sample codes, subject to ASIX

Q0002: How do I purchase the AX220xx WiFi module boards?
A0002: ASIX provides the AX22001 802.11b/g WiFi Module Board (with Airoha AL2230S RF chip) which is a RF calibrated and tested module. To shorten customer's hardware design cycle on RF circuit layout and RF testing during prototyping phase, customers can design your own base board with desired function and interface circuits and assemble it with the AX22001 802.11b/g WiFi Module Board through the pin header.

ASIX will provide more AX220xx WiFi module board solutions such as smaller form factor or with stamp holes (saving the pin header cost), etc. later. For most up-to-date information, please contact ASIX Sales staffs at sales@asix.com.tw.

You can visit the AX220xx Development Board web page for details of AX220xx WiFi module boards.
