Description
General part information
TMC2074 Series
The TMC2074 network controller is CircLink technology's flagship product. The TMC2074's flexibility and rich feature set enable a high-reliability and high-performance, real-time and control-oriented network without the cumbersome middle layer protocol stacks and complex packet prioritization schemes typically required.
TMC2074 operates at network data transfer rates up to 5 Mbps. Its embedded 1 kByte RAM can be configured into a maximum of 32 pages to implement a 31-node network where each node in the network has the same local memory.
The TMC2074 has two operational modes: "Peripheral Mode" and "Standalone Mode". It can operate with or without the existence of a system CPU on a network node. In Peripheral Mode, the TMC2074 has two selectable communication modes, "Free Format Mode" and "Remote Buffer Mode". Free Format mode, retained from ARCNET, is "packet oriented" communication. Remote Buffer mode communication is a CircLink-specific feature, and is a token oriented communication, which includes automatic data transmission when the token arrives.
