General Description
About TMC2074
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.PRODUCT FEATURES
