Overview

The MCP2515 is a standalone Controller Area Network (CAN) controller that implements the CAN specification, version 2.0B. It serves as an interface between a microcontroller and the CAN bus via a standard Serial Peripheral Interface (SPI), enabling CAN connectivity for MCUs that do not have an integrated CAN peripheral.

Why Choose This Part

The device supports CAN 2.0B with bit rates up to 1 Mb/s and features a low-power Sleep mode consuming only 5uA. Its SPI interface allows for simple integration with nearly any microcontroller while operating across a wide supply voltage of 2.7V to 5.5V.

Applications

Automotive Aftermarket Modules
Adding CAN connectivity to vehicle diagnostic tools or data loggers that use microcontrollers without native CAN support.
Industrial Control Networks
Implementing robust communication between PLCs, sensors, and actuators in factory automation environments.
Embedded Systems Expansion
Providing a second CAN channel to an existing system for gateway or bridging applications.

Getting Started

To use the MCP2515, you must pair it with a CAN transceiver like the MCP2551 or MCP2561 to handle the physical layer signaling. Development is supported by numerous open-source libraries, particularly for the Arduino ecosystem, and hardware testing can be performed using the MCP2515 PICtail Plus Daughter Board.
