Overview

The MCP2551-I/SN is a high-speed CAN transceiver providing the physical-layer interface between a CAN controller and the differential CAN bus. It supports bus rates up to 1 Mbps and is designed for a 5 V supply. The device is supplied in an SOIC-8 package for PCB mounting and implements the standard CAN physical layer.

Why Choose This Part

The MCP2551 is an industry-proven, widely used CAN transceiver offering straightforward integration with 5 V CAN controllers. Its SOIC-8 package and standard pinout make PCB layout and replacements simple, and it supports full 1 Mbps high-speed CAN links compatible with common CAN controllers and controllers-plus-transceiver arrangements.

Applications

Automotive in-vehicle networks
Interfaces ECUs, gateways, and body electronics to the vehicle CAN bus at up to 1 Mbps.
Industrial fieldbus and PLC communications
Provides reliable CAN physical-layer connectivity for machine control and sensor networks.
Motor drive and motion-control networks
Links motor controllers and drives where deterministic CAN messaging is required.
Embedded systems and robotics
Used for inter-module communications in robots, AGVs, and distributed embedded controllers.

Getting Started

Pair the MCP2551 with a CAN-capable microcontroller or with a CAN controller IC such as the MCP2515 (SPI CAN controller) to form a complete CAN node. On the physical bus, provide correct 120 ohm termination at each end, ensure common ground between nodes, and place the SOIC-8 device on a breakout or PCB for testing. Use a CAN-aware debugger, bus monitor, or logic analyzer with CAN decoding to validate messages while prototyping.
