What are the Networked Microcontrollers? What makes them unique?
Network microcontrollers allow designers to quickly and easily add Ethernet/Internet connectivity to their embedded systems. In addition to a 10/100 Ethernet MAC, the microcontroller has three serial ports, a controller area network (CAN) 2.0B controller, and 1-Wire Master networking capabilities. To enable access to the network, a full application-accessible TCP IPv4/6 network stack and operating system are provided in ROM. The network stack supports up to 32 simultaneous TCP connections and can transfer up to 5Mbps through the Ethernet MAC. • 4-clock cycle 8051 core • 16MB program memory + 16MB data memory contiguous addressing • 10/100 Base-T Ethernet MAC • Operation up to 75MHz (instruction cycle time of 54ns) • Low power modes • 3 serial ports • 4 automatic increment/decrement data pointers • 24 general-purpose I/O pins • 16/32-bit hardware math accelerator • 1-Wire Master • 64kB ROM • Full TCP/IPv4/v6 network stack • Memory manager • Multitasking operating system • Automatic netw
