DESCRIPTION

Description

OVERVIEW

Product Overview

The MCP2515 is a standalone CAN controller from Microchip in a TSSOP-20 package. It integrates CAN protocol handling and connects to a host controller through an SPI interface, allowing microcontrollers without a built-in CAN peripheral to join a CAN bus network. It includes message transmission and reception logic, acceptance filtering and interrupt management, reducing the software burden on the host. Typical uses include node communication in automotive electronics, industrial automation and distributed control systems. An external CAN transceiver is usually required for physical layer signal conversion.

APPLICATIONS

Applications

  • Used in automotive electronic nodes to exchange data with other controllers over a CAN bus.
  • Used in industrial automation equipment for distributed control network communication.
  • Used to add CAN communication capability to microcontrollers lacking a CAN peripheral.
  • Used in data acquisition terminals to upload collected data to a CAN bus.
FEATURES AND BENEFITS

Features and Benefits

  • Standalone CAN controller performs protocol handling internally.
  • SPI interface connects to various microcontrollers and reduces host resource usage.
  • Built-in acceptance filtering and interrupt management simplify software design.
  • Supports standard and extended frame formats for different network requirements.
  • TSSOP-20 package suits space-constrained surface-mount designs.
ADDITIONAL DETAILS

Additional Details

When purchasing, confirm the suffix and package, and check SPI timing requirements and the target operating environment. A CAN transceiver is usually required; the transceiver model can be confirmed together. The original datasheet should be used as the basis for electrical parameters.

Verify product details against the manufacturer datasheet before purchase.
