Overview
Description
The μPD720211 is a USB 3.0 hub controller that complies with the Universal Serial Bus (USB) Specification Revision 3.0 and operates at up to 5Gbps. The device incorporates Renesas' market-proven design expertise in USB 3.0 interface technologies and market-proven USB 2.0 hub core. It is fully compatible with all prior versions of USB spec and 100% compatible with Renesas' industry-standard USB 3.0 host controller. It comes in a small 56-pin QFN package and integrates several commonly required external components, making it ideally suited for applications with limited PCB space. In addition, the μPD720211 incorporates Renesas' low-power technologies and supports all mainstream battery charging specifications.
The μPD720211 USB 3.0 2-port hub reference design uses the µPD720211K8-701-BAL-A USB hub controller. The plug-and-play hub expands two USB 3.0 ports from a PC’s USB 3.x port. No driver is required for a common OS.
