Product Description

The AX11001/AX11005, 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 AX11001/AX11005 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 AX11001/AX11005, with popular TCP/IP protocol

suite on-chip and built-in 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.
