With the growing popularity of in-vehicle infotainment systems, car manufacturers are increasingly focused on creating seamless and intelligent connections between vehicle displays and various smartphones or tablets. As a leading provider of integrated circuits (ICs), Microchip Technology Inc. has introduced five new USB 2.0 smart hub ICs, offering automotive designers a range of flexible options to meet both technical and user experience requirements.
These ICs support multiple architectures, allowing for easy integration with major smartphone operating systems. They enable users to display mobile device interfaces on the car’s screen, combine with in-vehicle voice commands, charge devices, and even integrate advanced driver assistance features from smartphones into the infotainment system. This makes the driving experience more connected and efficient.
The new smart hubs can be cascaded across multiple rows of seats, ensuring that data is available on all ports simultaneously while also supporting charging. For example, one port can connect a phone to the car's main system, while another can charge and transfer data at the same time. With models like the USB4914, USB4916, USB4925, and USB4927, automakers can tailor their solutions to fit specific design needs, enhancing the overall user experience.
Mitch Obolsky, Vice President of USB and Networking Products at Microchip, emphasized the company’s leadership in providing reliable USB hub ICs for the automotive industry. He highlighted that Microchip’s patented technology enables unique host/device bus configurations, improving access to information and enhancing safety through better connectivity.
The new USB 2.0 Smart Hub ICs—USB4715, USB4914, USB4916, USB4925, and USB4927—feature single and dual bus implementations that offer robust connectivity to infotainment systems. These devices use standard USB drivers compatible with most automotive host systems, making it easier to develop and validate field-upgradable systems. Additionally, they include a 32-bit microcontroller for advanced bridging, audio support, and USB Power Delivery (PD).
For developers, Microchip provides application demonstration boards and evaluation kits for each of the new USB 2.0 smart hub ICs. These boards simulate real-world applications used by Tier 1 suppliers and OEMs. The company also showcased a USB-powered solution that complies with the USB PD 3.0 specification, demonstrating its commitment to innovation and performance in automotive electronics.
