USB4716

The Microchip USB4716 is a low-power, OEM configurable, MTT (Multi-Transaction Translator) USB 2.0 hub controller with 5 downstream ports and advanced features for embedded USB applications. Advanced features include FlexConnect capability on all downstream ports, IO bridging, and embedded 32 bit mico-controller. The USB4716 is compliant with the USB 2.0 Specification and is offered in commercial and industrial temperature ranges.

Microchip’s FlexConnect technology allows for easy port reversals or “role swapping” between the upstream host port and any downstream device ports. This unique capability allows for the smartphone ecosystem of software and applications to be connected to the automobile infotainment system, as well as enabling systems where the host can be switched between numerous USB hosts for improved sub-system control and performance.

Advanced IO bridging allows connectivity to be extended to GPIO, I2C, SPI, UART, and I2S so that the USB Smart hub becomes the center for system connectivity and control. The combination of IO bridging and an embedded 32 bit micro-controller enable the USB hub to provide key functionality for USB Power Delivery (PD) solutions where the micro-controller of executing PD contracts and interfacing to port controllers, port power devices, and power supply chips.

The USB4716 has been specifically optimized for embedded systems where high performance, and minimal BOM costs are critical design requirements. Standby mode power has been minimized and reference clock inputs can be aligned to the customer’s specific application. The USB-IF Battery Charger specification (revision 1.2) is supported on up and downstream ports, as well as Apple® and China profiles. In addition, all required resistors on the USB ports are integrated into the hub, including all series termination and pull-up/pull-down resistors on the D+ and D– pins

* DCP: Dedicated Charging Port (Power brick with no data) * CDP: Charging Downstream Port (1.5A with data) * SDP: Standard Downstream Port (0.5A with data) * Custom profiles also supported The USB4716 is the next generation of USB4604 which provides FlexConnect on all ports, advanced IO bridging, and a powerful 32 bit micro-controller capable of supporting USB Power Delivery solutions.
