Product Overview
The COM20020I-DZD is an embedded ARCNET Controller from standard Microsystems corporation. The device is a general purpose communications controller for networking microcontrollers and intelligent peripherals in industrial, automotive and embedded control environments using an ARCNET protocol engine. The flexible microcontroller and media interfaces, eight-page message support and extended temperature range of the COM20020ID make it the only true network controller optimized. 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 5Mbps when using the COM20020ID.
