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