GENERAL DESCRIPTION
The DS80C410/DS80C411 network microcontrollers offer the highest integration available in an 8051 device. Peripherals include a 10/100 Ethernet MAC, three serial ports, an optional CAN 2.0B controller, 1-Wire® Master, and 64 I/O pins. To enable access to the network, a full applicationaccessible TCP IPv4/6 network stack and OS are provided in the ROM. 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 DS80C410 and DS80C411 provide four data pointers, each of which can be configured to automatically increment or decrement upon execution of certain data pointer-related instructions. High-speed shift, normalization, accumulate functions and 32-bit/16-bit multiply and divide operations are optimized by the DS80C410/DS80C411 hardware math accelerator. 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.
