Can communication single wire?

Can communication single wire?

The SAE J2411 single-wire specification is for CAN network applications with low requirements regarding bit rate and bus length. The communication takes place via just one bus line with a nominal data rate of 33,3 kbit/s (83,3 kbit/s in high-speed mode for diagnostics).

How do 1-wire devices identify themselves?

Each 1-Wire slave device has a unique, unalterable, factory-programmed, 64-bit identification number (ID), which serves as device address on the 1-Wire bus. The 8-bit family code, a subset of the 64-bit ID, identifies the device type and functionality.

CAN bus with single wire system?

Overview

• CAN bus operates with a single wire.
• Operates directly from a vehicle’s 12 V battery system or a broad range of DC-power sources at low or high (33.33 kbps or 83.33 kbps) data rates.
• A high-voltage wake-up feature allows the device to control the regulator used in support of the MCU and other logic.

What is a single wire CAN?

The single-wire CAN transceivers allow the CAN protocol to be transmitted over one wire. The result is cost reduction for networks that don’t require full, high-speed CAN transmissions. The eight-pin and 14-pin devices drop into the same board layout for cost savings and increased flexibility.

CAN protocol is also suitable for?

CAN is a protocol for short messages. Each transmission can carry 0 – 8 bytes of data. This makes it suitable for transmission of trigger signals and measurement values. It is a CSMA/AMP ( Carrier Sense Multiple Access / Arbitration by Message Priority ) type of protocol.

CAN low speed termination?

Low-Speed/Fault-Tolerant CAN Termination For low-speed/fault-tolerant CAN, each device on the network needs a termination resistor for each data line: R(RTH) for CAN_H and R(RTL) for CAN_L. Unlike the high-speed CAN termination, low-speed CAN requires the termination to be on the transceiver rather than on the cable.

CAN is message based protocol?

CAN protocol is a message-based protocol, not an address based protocol. This means that messages are not transmitted from one node to another node based on addresses. Embedded in the CAN message itself is the priority and the contents of the data being transmitted. This is called a Remote Transmit Request (RTR).
