The TUSB542RWQR is an automotive-grade USB 2.0 hub compliant with USB 2.0 specifications. It is a single-chip solution that integrates a USB 2.0 hub controller, embedded USB 2.0 transceivers, USB 2.0 physical layer switches, and an integrated power field effect transistor (PFET) to provide true plug-and-play connectivity for in-vehicle infotainment systems. TUSB542RWQR is a solution for automotive infotainment systems that require USB 2.0 ports to communicate with downstream devices through a data bus between the host microcontroller and TUSB542RQR, thereby providing the gateway to peripheral devices connected to the USB hub. It is suitable for applications such as USB 2.0 attachable radio, display, and multimedia players.

TUSB542RWQR is an interface between USB data bus and Human Interface Devices (HIDs) such as keyboards, mouse, and touchpads. It is a window between a computer and a USB host controller, allowing devices to communicate with each other. TUSB542RWQR allows the host controller to communicate with downstream device such as storage devices, digital cameras, scanners, and other USB-affiliated devices without needing special adapters or drivers.

TUSB542RWQR offers both high-speed and Full-speed USB operations. It supports up to 7 downstream ports to connect multiple devices simultaneously and allows for hot plugging for peripherals. The integrated power FET provides active power to the downstream ports and is capable of providing more than 250mW of current per port. The TUSB542RWQR is ideal for compact designs and features a small form factor with a tiny 28-SOIC package that can be mounted in the tightest of areas.

The TUSB542RWQR provides integrated buffer and repeater functions to support a wide range of applications. These functions are programmed to optimize data transfer for efficiency and reliability when transmitting signals. Moreover, the TUSB542RWQR is designed with integrated splitters to accommodate more than one downstream device. Data splitters allow users to spread data across multiple separate devices to increase the speed of data transfer over the original single device.

In conclusion, the TUSB542RWQR is a solution for automotive infotainment systems to provide plug-and-play connectivity for in-vehicle infotainment systems. It is ideal for applications such as radio, display, and multimedia players, and can accommodate more than one downstream device with integrated buffer, repeater, and splitter functions. It is a single-chip solution that integrates USB 2.0 hub controller, embedded USB 2.0 transceivers, USB 2.0 physical layer switches, and an integrated power FET to provide true plug-and-play connectivity.
