Microchip: single-port USB smart hub ICs optimise system costs for automotive

Microchip announces the introduction of new single-port USB Smart Hub ICs to extend its family of USB automotive products, to give automotive manufacturers the ability to provide dependable and convenient connectivity while optimising system costs. The USB4912 and the USB4712 provide what is required for single-port implementations and can be used to add a single port under the radio, in the centre console or together with wireless charging implementations.

Using the same patented methods as the multi-port family, the USB 2.0-compliant devices offer single-port Integrated Circuits (ICs) in smaller footprint packages, optimising a customer’s Bill of Materials (BoM) and lowering total system costs. Now with both single-and multi-port options which share the same software, designers can choose configurations and seamlessly implement solutions that fit their designs and get to market faster. These diverse USB solutions support smartphones, tablets and other connected devices, without compromising signal integrity.

By using native USB drivers and mechanisms such as Microchip’s patented role-swapping technologies, multi-host reflector and FlexConnect, the USB4912 and the USB4712 Smart Hub ICs optimise design and easily integrate with infotainment head units, allowing a seamless connection with the smartphone ecosystem of software and applications. Each device includes an embedded 32-bit microcontroller (MCU) for the implementation of USB I/O bridging. Both devices support USB 2.0 Low Speed, Full Speed and Hi-Speed with a single USB 2.0 Hi-Speed upstream port for host connection. As a low-power, configurable, USB 2.0 hub controller, the USB4912 allows connectivity to be extended to GPIO, I2C, SPI and UART so that the USB Smart Hub becomes the centre for system connectivity and control. The USB4712 and USB4912 are offered in a 40-pin VQFN package, compliant with the USB 2.0 specification and have passed AEC-Q100, grade 3 testing.
