The AX11015, Single Chip Microcontroller with TCP/IP and 10/100M Fast Ethernet MAC/PHY, is a System-on-Chip (SoC) solution which offers a high performance embedded micro controller and rich communication peripherals for wide varieties of application which need access to the LAN or Internet. With built-in network protocol stack, the AX11015 provides very cost effective 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. In addition to stand-alone application, the AX11015, with popular TCP/IP protocol suite on-chip and built-in local bus host interface, I2C bus, or SPI bus, can be used as network co-processor to offload TCP/IP protocol processing loading from system CPU in an embedded system
