Interface and Connectivity


CAN Bus and CAN FD Bus Products and Solutions

Bring communication and connectivity in your embedded design to the next level with Microchip's Controller Area Network (CAN) bus solutions technology. Originally created for automotive applications, the CAN protocol is a high-speed, reliable communication protocol for applications requiring robust communication at bit rates reaching 8 Mbps. Incorporating the CAN protocol into your design is a cost-effective communications option which enables a high degree of real-time capability for simple to complex electrical environments.

Microchip offers a complete line of products to meet the needs of high-performance embedded applications using the CAN protocol, including 8-bit, 16-bit and 32-bit microcontrollers, 32-bit microprocessors and digital signal controllers (DSCs) with integrated CAN, external CAN controllers and CAN transceivers. With easy-to-use development systems, code examples, drivers and application notes, Microchip provides a total CAN bus solution that enables low-risk product development, lower total system cost and faster time to market for your high-performance, embedded design.

CoaXPress® Technology

CoaXPress® technology is a standard for high-performance machine vision, industrial inspection and traffic monitoring systems. CoaXPress is the state-of-the-art method for connecting high-performance, high-resolution cameras to high-speed capture cards (i.e. frame grabbers).

CoaXPress operates over standard 75-ohm, 50-ohm and shielded differential pair cables. CoaXPress Version 1.1 currently supports up to 6.25 Gbit/s per cable from the camera to the frame grabber. For the trigger and control function up to 20 Mbit/s can be sent simultaneously in the opposite direction via the same cable. Power is also supplied over the cable from the frame grabber to the camera. Furthermore, the CoaXPress standard allows for a number of cables to be used in parallel; for example, four cables offering up to 25 Gbit/s image data streaming with CoaXPress 1.1.

CoaXPress is the only open and royalty free standard that allows video, camera control and triggering, and up to 13W of power to be delivered via a single, off-the-shelf 75Ω coaxial cable up to 100m with standard BNC, Micro BNC or DIN1.0/2.3 connectors.

CoaXPress is also supported by GenICam, an Application Programming Interface standardized by European Machine Vision Association (EMVA) and has been widely adopted by many industry partners. It accelerates and simplifies application development as well as upgrading components of visions systems.

Infrared Products and Solutions

Microchip's infrared products are designed to meet a variety of application needs with distinct advantages that enable the embedded system designer to easily add infrared wireless connectivity.

Microchip's product offering includes simple bit-encoding/decoding devices to complex products that embed the IrDA® protocol stack plus bit encoding/decoding functionality on one small 18-pin device.

INICnet™ Technology for Automotive Multimedia Networking

INICnet™ technology simplifies automotive infotainment networking with support for Ethernet, audio, video and control over a single cable. INICnet can coexist with automotive Ethernet to seamlessly interface Internet Protocol (IP)-based data communications across vehicle domains, while providing efficient transport of audio and video data. INICnet does not require development and licensing of additional protocols or software stacks, reducing development costs and keeping development on schedule. INICnet supports a variety of system management methodologies via IP, or a dedicated control message channel. Data rates of 50 Mbps on UTP, or 150 Mbps on coax or optical cabling, are supported.

  • Integrated network management
  • Fast network start-up (off to full network availability in about 120 ms)
  • Industry-standard application interfaces, including I2S, USB, SPI, MediaLB, I2C
  • Synchronization - the same clock is available at all nodes in the system

  • ECU power management support
  • Multiple data types simultaneously supported: audio, video, packet, message


Reliable, Low-Cost Networking

Low-cost Local Interconnect Network (LIN) systems are used throughout the automobile in comfort, powertrain, sensor, and actuator applications.

The modular Microchip LIN family ranges from simple transceiver ICs to complex system basis chips with LIN transceiver, voltage regulator and watchdog. At higher integration levels, the Microchip System-in-Package (SIP) solutions feature an AVR®, an Arm® Cortex® M0+ microcontroller or PIC® microcontroller, LIN transceiver, voltage regulator and watchdog in a single package.

Key Features

  • High level of integration – Depending on the individual integration level, we embed a large number of functions into our LIN devices, including LIN transceiver, voltage regulator, watchdog and microcontroller, so you don’t have to add these capabilities later.
  • Broad portfolio – Microchip gives you the broadest in-vehicle networking (IVN) product portfolio on the market with modular families at all integration levels to meet diverse application requirements.
  • Proven reputation – Approval of all major car manufacturers is available.
  • Advanced application support – A broad range of development tools give you a quick start on developing, prototyping and testing new designs.
  • Family footprint – The ATA6632/33/34 series of devices also provide a family footprint so designers can upgrade their designs with various devices within these series.
