Dallas MCU supports IPv4, v6

The DS80C400 networked microcontroller chip from Dallas Semiconductor Corp. integrates a high-speed 8051 core, a 10/100 Ethernet MAC, and a silicon software TCP IPv4/v6 stack to provide network connectivity to devices such as MP3 players, web cameras, and industrial equipment.

Available in a 100-pin LQFP, the MCU operates at a clock speed of up to 75MHz and can be connected directly to IP networks. It also includes three synchronous/asynchronous serial ports that operate up to 18.75Mbps, a CAN2.0B controller, up to 64 I/Os, and a 1-Wire master. Protocol support is also extended for TCP, UDP, IGMP, ICMP, TFTP, and DHCP.
