Overview

The MCP2515 is a standalone Controller Area Network (CAN) controller that implements the CAN Specification Version 2.0B. It provides a Serial Peripheral Interface (SPI) for easy integration with microcontrollers, offloading the host MCU from managing the full CAN protocol stack. This allows microcontrollers without integrated CAN hardware to communicate on a CAN bus.

Why Choose This Part

The MCP2515 simplifies the addition of CAN communication to any microcontroller with an SPI interface, reducing complexity and bill of materials compared to using a microcontroller with integrated CAN. Its support for CAN 2.0B, multiple buffers, and programmable filters ensures flexible and reliable message handling. The low-power CMOS technology and Sleep mode contribute to energy-efficient designs.

Applications

Automotive Diagnostics
Enabling non-CAN-equipped microcontrollers to interface with automotive On-Board Diagnostics (OBD) systems for vehicle monitoring and control.
Industrial Automation
Connecting embedded systems in factory automation, robotics, and process control to a CAN network for robust and real-time data exchange.
Building Automation
Integrating lighting, HVAC, and security systems into a unified communication network using CAN.
Medical Devices
