DCAN500-IC

Overview

The DCAN500-IC is a CAN over Powerline transceiver manufactured by Yamar Electronics Ltd. It enables CAN A/B protocol communication over noisy DC or AC power lines, supporting host bitrates up to 1Mbit/s. The device utilizes phase modulation of a sine wave carrier at selectable frequencies between 5MHz and 30MHz with 100 kHz spacing. It features a QFN32 5x5 mm package, built-in arbitration mechanisms, and sleep modes for low power consumption.

Feature Summary

• Supports multiple independent CAN networks operating simultaneously over a single shared powerline using distinct carrier frequencies.
• Integrates a built-in Carrier Sense Multiple Access/Carrier Detection (CSMA/CA) mechanism for automatic bus arbitration.
• Provides configurable sleep modes to minimize power consumption during periods of inactivity.
• Includes channel interference detection capabilities to monitor signal integrity on the powerline.

Applications

• Multiple vehicle CAN networks sharing the same powerline
• Aerospace CAN networks
• Sensors and actuators buses
• Robotics control networks
• Truck-Trailer redundant CAN communication

Procurement Notes

Verify the specific suffix 'IC' against the official Yamar datasheet DS-DCAN500 to confirm pinout compatibility and electrical specifications. Ensure the selected component matches the required carrier frequency range and bitrate configuration for your specific application environment.

Selection Notes

Select this component when eliminating dedicated CAN bus wiring is required to save weight and simplify installation. Ensure the design accommodates external passive components such as bandpass filters and crystals, as specified in the implementation guidelines.

Part Context

This device belongs to the DCAN series of powerline communication transceivers designed for robust data transmission over existing electrical infrastructure. It serves as an alternative to traditional twisted-pair CAN cabling in environments where cable management is challenging.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires verifying interface compatibility and carrier frequency support with equivalent powerline transceivers.
