Network Microcontrollers with Ethernet and CAN

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. The DS80C410 and DS80C411 also include 64KB internal SRAM for user application storage and network stack.

To enable access to the network, a full application accessible TCP IPv4/6 network stack and OS are provided in the 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 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.
