Peripheral Mode CircLink™ Controller

SMSC TMC2072
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.
