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 applicationaccessible 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 systemclock frequency of 75MHz results in a minimum instruction cycle time of 54ns.
