Networked Microcontroller Provides Low-Cost Connectivity

Connecting products directly to IP networks and priced at less than $9 each/1,000, the DS80C400 microcontroller is designed to provide a low-cost means of embedding network connectivity capabilities in MP3 audio players, web cameras, vending machines, home/office automation equipment, remote data collection systems, and a host of other products. With a maximum system clock frequency of 75 MHz, this fast, 8051-compatible µC is said to provide ample speed to perform local control chores while also servicing network requests—the controller boasts of a minimum instruction cycle time of 54 ns. In addition to its 8051 core, the DS80C400 networked microcontroller has on-chip a 10/100 Mb Ethernet MAC and silicon software TCP IPv4/v6 stack, as well as three synchronous/asynchronous serial ports that can operate at speeds up to 18.75 Mbps, a CAN2.0B controller, up to eight ports (64 I/O pins), memory, and a 1-Wire master. The controller comes in a 100-lead LQFP, has an operating temperature range of -40°C to +85°C, and, by using the DS80C400 reference design, reportedly enables embedded web servers to be built in just hours. The company’s Tiny Internet Interface (TINI) runtime environment is available at Application code can be written in Java or C. DALLAS SEMICONDUCTOR, Dallas, TX. (800) 998-8800.
