SMSC's COM20020I 3V is a member of the family of Embedded ARCNET Controllers from Standard Microsystems Corporation. The device is a general purpose communications controller for networking microcontrollers and intelligent peripherals in industrial and embedded control environments using an ARCNETprotocol engine. The flexible microcontroller and media interfaces, eight-page message support, and extended temperature range of the COM20020I 3V make it the only true network controller optimized for use in industrial and embedded applications. Using an
ARCNET protocol engine is the ideal solution for embedded control applications because it provides a deterministic token-passing protocol, a highly reliable and proven networking scheme, and a data rate of up to 5 Mbps when using the COM20020I 3V.
