X-CAN-2

 Sorcus Logo
  • 2 independent CAN channels
  • Each channel is electrically isolated
  • 1 Mbit/s CAN module with full CAN functionality
  • Supports CAN specifications 2.0 A and 2.0 B (11 and 29-bit identifiers)
  • Bus termination resistor for each channel can be switched in by software
  • Can be supplied with fault-tolerant ()ISO 11519) or high-speed (ISO 11898) CAN interface
Description

The module provides 2 independent CAN bus channels. The CAN protocol is handled by one controller per channel. The channels can be supplied with fault-tolerant (ISO-DIS 11519; up to 125 kBit/s) or high-speed (ISO-DIS 11898; up to 1 MBit/s) interfaces.
The fault-tolerant interfaces can detect faults, e.g. a line that is shorted to ground, and automatically take appropriate action to continue the communication.
