Single-port automotive USB Smart Hub ICs optimize system costs
Chipmaker Microchip Technology (Chandler, AZ) has announced that it has extended its automotive USB 2.0 Hi-Speed family with new one-port devices.

The company introduced new single-port products to its USB 2.0 Smart Hub IC family, providing automakers with more options to fit varying design needs. The USB4912 and the USB4712, says the company, are ideal for adding a single port under the radio, in the center console, or alongside wireless charging implementations.

"The development of these devices is a direct response to customer demand for single-port implementations," says Charles Forni, vice president of Microchip's USB and Networking business unit. "Building on Microchip's leadership in the multi-port space, we now offer everything from one to four ports that support USB 2.0 and USB 3.0."

The USB 2.0-compliant devices offer single-port ICs in smaller footprint packages and share the same software with multi-port options, enabling designers to easily choose configurations and implement solutions that fit their designs. The USB solutions support smartphones, tablets, and other connected devices.

The USB4912 and the USB4712 Smart Hub ICs, says the company, optimize 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, while the USB4912 - a low-power, configurable, USB 2.0 hub controller - allows connectivity to be extended to GPIO, I2C, SPI, and UART so that the USB Smart Hub becomes the center for system connectivity and control.

Both USB products are offered in a 40-pin VQFN package, compliant with the USB 2.0 specification, and have passed AEC-Q100, grade 3 testing. The USB4712 is available for $1.60 and the USB4912 is available for $1.89, each in 10,000-unit quantities.
