Overview

The MCP2515-I/SO is a stand-alone Controller Area Network (CAN) controller that implements the CAN specification, version 2.0B. It is designed to handle all CAN protocol functions including message filtering, buffering, and management, offloading these tasks from the host microcontroller via a high-speed SPI interface.

Why Choose This Part

The device features dual receive buffers and three transmit buffers with prioritized message storage, reducing the real-time processing overhead on the host MCU. It supports a wide supply voltage range from 2.7V to 5.5V and consumes only 1uA in standby mode, making it suitable for battery-powered or low-power applications.

Applications

Vehicle Diagnostics
Used in OBD-II readers and vehicle data loggers to interface with the automotive CAN bus.
Industrial Automation
Provides reliable communication for sensors and actuators in noisy industrial environments.
Legacy System Upgrades
Enables CAN connectivity for older microcontrollers that lack an integrated CAN peripheral.
Motor Control Networks
Coordinates multiple motor drives in robotics and CNC applications using the CAN 2.0B protocol.
