AX11015, Microcontroller with Ethernet Controller and TCP/IP

The AX11015 is a 8051 / 80390 compatible microcontroller with on-chip ethernet controller, TCP/IP stack and 10/100M ethernet MAC/PHY. By those on-chip features, AX11015 offers simple, easy, and low cost ethernet networking solution  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.

The AX11015 is one of the ASIX ’s AX110xx microcontroller family. The AX11001/AX11005 and AX11015 MCUs can run up to 100MIPS. They have 128 to 512 KBytes flash memory, and 32KBytes of RAM. The AX110xx family also supports I2C, SPI bus, three UART (up to 921.6Kbps), and Dallas 1-wire.
