SMSC CircLink(TM) Technology Enables Low-Cost, High-Performance, Modular Design of Complex Systems for Industrial Networked Applications.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- SMSC SMSC Short Message Service Center SMSC Standard Microsystems Corporation (New York) SMSC Spiritual Moral Social Cultural (education) SMSC Stephenville Medical and Surgical Clinic today announced its TMC TMC Technology Marketing Corporation (Norwalk, Connecticut) TMC Texas Medical Center (Houston, TX) TMC Traffic Message Channel TMC The Movie Channel TMC Traffic Management Center 2072, TMC2074 and TMC2084 controllers - all based on SMSC CircLink(TM) technology, which enables modular system design. CircLink, a derivative of the ARCNET (Attached Resource Computer NETwork) The first local area network (LAN) introduced in 1968 by Datapoint Corporation. It connects up to 255 nodes in a star topology at 2.5 Mbits/sec over twisted pair or coax. A 20 Mbits/sec version was introduced in 1989. networking protocol, provides a simple communication backbone, which can be used to link controllers, actuators and other parts of a complex system. Target applications include printers, home appliances, vending, gaming and copying machines, security, lighting and climate control systems and industrial equipment. With CircLink, designers can replace bulky wiring harnesses with a simpler, cost-effective modular design In the context of systems engineering, modular design — or "modularity in design" — is an approach aiming to subdivide a system into smaller parts (modules) that can be independently created and then used in different systems to drive multiple functionalities. approach. SMSC's CircLink technology is based on the proven token-passing protocol, which has been improved through patented enhancements. A key advantage of CircLink is its "Standalone stand·a·lone adj. Self-contained and usually independently operating: a standalone computer terminal. Mode," which allows nodes to operate on the network without a local host processor, and reduces the cost associated with modular design. CircLink allows these "Slave" nodes to be controlled through one or more "Master" nodes and multiple "Master" nodes can co-exist on the same network. Another advantage of CircLink is that it requires minimal software. For instance, CircLink does not require a protocol stack The set of protocols used in a communications network. A protocol stack is a prescribed hierarchy of software layers, starting from the application layer at the top (the source of the data being sent) to the data link layer at the bottom (transmitting the bits on the wire). , such as TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. , to operate. The CircLink protocol is implemented entirely in the controller. If the operating system operating system (OS) Software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. is not used, even the device driver is not needed. Applications can directly interface to the CircLink controller through simple communication software, which is provided for free by SMSC. CircLink provides deterministic 1. (probability) deterministic - Describes a system whose time evolution can be predicted exactly. Contrast probabilistic. 2. (algorithm) deterministic - Describes an algorithm in which the correct next step depends only on the current state. network behavior, which is important to control systems. As a result, cycle times are predictable. In addition, CircLink provides several value-added features, including Network Standard Time (NST NST nonstress test.

Together, these features provide robust, simple and highly-synchronized communication for modular systems. CircLink's flagship controller, the TMC2074, is equipped with all the above mentioned unique features and can operate in both "Standalone Mode" and "Peripheral Mode," in which a local host processor is required. The TMC2072 is a lower pin count version of the TMC2074 without the "Standalone Mode." Lastly, the TMC2084 CircLink Standalone Mode controller features a small footprint and package.
