Description

FULL DATA SHEET Download Rev 7 (PDF, 1.8MB) E-Mail The DS80C400 network microcontroller offers the highest integration available in an 8051 device. Peripherals include a 10/100 Ethernet MAC, three serial ports, a CAN 2.0B controller, 1-Wire® Master, and 64 I/O pins. To enable access to the network, a full application-accessible TCP IPv4/6 network stack and OS are provided in ROM. The network stack supports up to 32 simultaneous TCP connections and can transfer up to 5Mbps through the Ethernet MAC. Its maximum system-clock frequency of 75MHz results in a minimum instruction cycle time of 54ns. Access to large program or data memory areas is simplified with a 24-bit addressing scheme that supports up to 16MB of contiguous memory. To accelerate data transfers between the microcontroller and memory, the DS80C400 provides four data pointers, each of which can be configured to automatically increment or decrement upon execution of certain data pointer-related instructions. The DS80C400's hardware math accelerator further increases the speed of 32-bit and 16-bit multiply and divide operations as well as high-speed shift, normalization, and accumulate functions. The High-Speed Microcontroller User's Guide and the High-Speed Microcontroller User's Guide: Network Microcontroller Supplement should be used in conjunction with this data sheet.
