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.
  • Programmable reconfiguration times
  • Deterministic (ANSI 878.1) token passing ARCNET protocol
  • Minimal microcontroller and media interface logic required
  • Flexible interface for use with all microcontrollers or microprocessors
  • Automatically detects type of microcontroller interface
  • 2k x 8 on-chip dual port RAM
  • Command chaining for packet queuing
  • Sequential access to internal RAM
  • Software programmable node ID
  • Eight 256-byte pages allow four pages TX and RX plus scratch-pad memory
  • Next ID readable
  • Internal clock scaler and clock multiplier for adjusting network speed
  • Self-reconfiguration protocol
  • Supports up to 255 nodes
  • Supports various network topologies (star, tree, bus)
  • Duplicate node ID detection
  • Powerful diagnostics
  • Receive all packets mode
  • Traditional hybrid interface for long distances up to four miles at 2.5Mbps
  • RS485 differential driver interface for low power, high reliability
