The AX220xx family, from ASIX Electronics, is a single chip microcontroller with TCP/IP and 802.11 WLAN MAC/baseband. The AX220xx is the latest member added to ASIX's embedded network SoC product portfolio.
Leveraging prevalent Wi-Fi infrastructure in the home and office environment, the single-chip Wi-Fi SoC provides cost competitive wireless connectivity for bridging uncompressed digital audio data, compressed digital video data and serial/parallel user data through its versatile interfaces over the Wi-Fi network.
AX220xx is a System-on-Chip (SoC) that offers a high performance dual-CPU architecture with 1-MB on-chip shared Flash as program memory, 64-KB on-chip data memory for the main CPU (MCPU), 32-KB on-chip data memory for the 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 AX220xx 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 an Infrastructure or ad-hoc (IBSS) network topology.
In addition to standalone applications, the AX220xx with TCP/IP protocol suite running on-chip and support for various parallel and serial host interfaces, 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.
There is a growing need to add wireless network connectivity into embedded systems, such as adding remote control capability to embedded devices and enabling a user's smartphone to take control over Wi-Fi. Machine-to-Machine (M2M) or Internet of Things (IoT) communications. Tailor made for this embedded market, the SoC provides cost effective wire or wireless networking to enable simple, easy, and low cost Internet connection capability for many applications, such as consumer electronics, networked home appliances, Wi-Fi speaker, industrial equipments, security systems, remote data collection equipment, remote control, remote monitoring, and remote management.
To help customers evaluate and develop applications with the AX220xx product family, ASIX provides comprehensive technical support information in a development/reference design kit. The kit includes the hardware and software application notes, user guides, schematics, PCB layout guide, and the firmware C source code for the AX220xx family.
