CAN
Many PHYTEC Single Board Computer subassemblies offer integrated CAN (Controller Area Network) capability. Originally developed for the automotive industry, CAN and its associated higher-layer protocols allow high-efficiency, prioritized and synchronized networking of distributed sensors and microcontrollers via message identifier signals. The CAN protocol is similar to Ethernet in that it is a collision detection system. It offers transmission speeds of up to 1 Mbit/sec, data integrity, host processor unloading and flexible and powerful message passing between up to 110 nodes on a CAN bus. Unlike Ethernet, CAN supports immediate throughput of messages according to defined priority hierarchies. On account of its functionality, CAN is finding increasing use in networked process and automated control applications.
