About the TMC2072

The TMC2072 network controller is CircLink technology’s flagship product. The TMC2072’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.

TMC2072 operates at network data transfer rates up to 5 Mbps. Its embedded 1k Byte 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.

TMC2072 supports “Peripheral Mode” operation, which includes 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.

The TMC2072 has a flexible 8-bit or 16-bit data bus to interface various CPU types including X86, 68XX,

and SHx with multiplexed or non-multiplexed address/data. When operating in Peripheral mode, the

TMC2072 has 8-bit programmable I/O available. When operating in Standalone mode, the TMC2072’s I/O

configuration is16-bit. The TMC2072 also integrates a 3-port hub (two ports for external connection) to

accommodate various network topologies (Bus, Star, etc.) and combinations.
