Beschreibung

Microchip’s USB5806 SmartHub is a 6 port, SuperSpeed (SS)/Hi-Speed (HS), low power, configurable and fully compliant with the USB 3.1 Gen1 specification. The USB5806 also supports Full Speed (FS) and Low Speed (LS) USB signaling, offering complete coverage of all defined USB operating speeds. The new SuperSpeed hubs operate in parallel with the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic. A SmartHub is defined as a USB hub that integrates system levels functions typically associated with a separate MCU or processor. The USB5806 SmartHub enables communication to other peripherals in addition to USB. This I/O Bridging capability allows the host to seamlessly interface to peripherals via I2C, SPI or GPIOs over USB. The USB5806 also enable a downstream device to take control of the host system by swapping roles and becoming the host port. The USB5806 can also switch between two different hosts if required. This role changing technology is called FlexConnect and can be initiated through hardware or software commands. New technologies like the USB Type-C connector and power delivery are changing the USB landscape. Designed to simplify the latest USB hub designs, the USB5806 has built in Billboard support giving you the option to offload this function from the power delivery controller onto the hub. In addition, the hub can expand beyond six ports through PortSplitting which allows for embedded applications to only use the interface needed for internal USB connections.ProTouch2, Microchip’s proprietary software utility, can be used to program On-chip One Time Programmable (OTP) ROM for the USB5806 which stores required register settings to ensure the desired start up configuration at power on. All LED, GPIOs and port control signal pins are under firmware control, allowing for maximum operational flexibility. However, for even more simplicity, the USB5806 can be configured through a series of external low-cost resistor bootstraps. A handful of bootstap pins are available on the USB5806 to enable standard configurations for GPIOs and downstream ports. No OTP programming required.
