The CJMCU-1051 TJA1051 CAN Transceiver Module provides the physical-layer interface between a CAN controller and the CAN bus, converting logic-level transmit and receive signals into differential CAN bus signals. BDTronics offers this module for Arduino, microcontroller, automotive electronics, industrial automation, robotics and embedded CAN communication projects.

Based on the TJA1051 high-speed CAN transceiver, the module supports CAN communication speeds of up to 1 Mbit/s and is designed for high-speed CAN network nodes. The TJA1051 is an upgraded successor to the widely used TJA1050, with improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance.

The TJA1051 provides differential CAN transmit and receive functions while allowing the CAN controller to communicate with the physical CAN bus. Compatible TJA1051 variants support direct connection between the transceiver I/O and 3V to 5V microcontroller interfaces.

CAN Communication:

A CAN controller typically handles CAN protocol processing, while the TJA1051 transceiver provides the physical-layer interface to the CAN bus. The transceiver converts the controller's logic-level transmit signal into differential CAN bus signaling and converts received CAN bus signals back into a logic-level receive signal.

This allows microcontrollers without an integrated physical CAN transceiver to connect to a CAN network when paired with an appropriate CAN controller or microcontroller with CAN functionality.

Applications:

The CJMCU-1051 is suitable for:

• Arduino CAN bus projects

• Microcontroller CAN communication

• Automotive CAN bus systems

• Vehicle electronics

• Industrial automation

• Robotics

• Motor controllers

• Embedded control systems

• Battery management systems

• Solar and power electronics communication

• CAN-based sensor networks

• Industrial monitoring systems

• Machine-to-machine communication

• High-speed embedded CAN networks

TJA1051 vs TJA1050:

The TJA1051 is an upgraded high-speed CAN transceiver designed as a successor to the TJA1050 family. It provides improved EMC and ESD performance while maintaining the basic role of interfacing a CAN controller with the physical CAN bus.

Important Notes:

• The module is a CAN transceiver, not a complete standalone CAN controller.

• A suitable CAN controller or microcontroller with CAN functionality is required for CAN communication.

• Maximum communication speed is up to 1 Mbit/s under appropriate CAN network conditions.

• Use proper CAN bus termination and wiring practices when building a CAN network.

• The TJA1051 does not provide bus-wake standby functionality.
