Microchip Technology announces new USB 2.0 smart hub ICs range,available in a variety of architectures, the new devices offer increased flexibility to fit car manufacturers’ design needs and meet consumer demand for easy-to-use, intuitive systems.

With Microchip’s new USB4914, USB4916, USB4925, and USB4927 smart hub ICs, car makers can customise solutions to meet their design needs. As the car becomes more of an entertainment environment, manufacturers can create solutions that allow consumers, for example, to use one phone for navigation and another for music or video.

The five new rolled out devices enable:

  • Multiple architectures so manufacturers can implement their design of choice to easily interface with all major smartphone operating systems.
  • These systems allow the graphical user interface of the phone or tablet to be displayed on the vehicle’s screen and enable integration with voice commands inside the car, all while simultaneously charging the mobile devices.
  • They also enable driver assistance applications on mobile handsets to be integrated with an automobile’s infotainment system.

Microchip’s new smart hub ICsenable cascading of the hubs to the second- and third-row seats with simultaneous data and charging in all ports. For example, if there are dual USB ports, one port can connect the phone or tablet to the head unit, leaving the other port free to charge and upload/download data.

“Microchip is the leader in USB hub ICs for the automotive industry,” says Mitch Obolsky, vice president of Microchip’s USB and Networking Group. “Our long-term investment delivers patented technology that provides unique host/device bus configurations for handset connectivity into vehicles to allow better access to information and safer driver assistance and communication.”

Microchip’s new USB4715, USB4914, USB4916, USB4925 and USB4927USB 2.0 smart hub ICs provide unique USB configurations including single-and dual-bus implementations for optimal connection to infotainment systems. All devices operate with standard USB drivers present in most automotive head units for faster development, system validation and field updates. Each device also contains an integrated 32-bit micro controller for advanced bridging, audio application support and USB Power Delivery (USB PD).

Development Support

A demonstration application board and evaluation board are available for each of the new USB 2.0 smart hub ICs.
