Overview

The MCP2515 is a stand-alone CAN controller that implements the CAN specification, version 2.0B. It is capable of transmitting and receiving both standard and extended data and remote frames, interfacing with microcontrollers via an industry-standard SPI interface.

Why Choose This Part

The device features three transmit buffers and two receive buffers with sophisticated filtering and masking to reduce the host MCU overhead. It operates over a wide 2.7V to 5.5V range and consumes only 10mA during active operation, making it suitable for both 3.3V and 5V logic systems.

Applications

Automotive Networking
Connecting auxiliary sensors and control modules to the vehicle's primary or secondary CAN bus networks.
Industrial Automation
Implementing robust communication in factory floor equipment and PLCs that require high noise immunity.
OBD-II Diagnostic Tools
Building custom interfaces to read engine parameters and diagnostic trouble codes from passenger vehicles.
Robotics
Managing distributed motor controllers and sensor nodes in complex robotic platforms using a reliable multi-master bus.

Getting Started

To use this controller, connect it to your MCU via SPI and provide a clock source, typically a 16MHz or 20MHz crystal. You will also need an external CAN transceiver, such as the MCP2551 or MCP2562, to interface with the physical differential bus lines.
