Microchip’s USB5926C [SmartHub](https://www.microchip.com/en-us/products/interface-and-connectivity/usb/usb-hubs/smarthub-ics)™ is a 6 port, SuperSpeed (SS), low power, configurable USB3.2 Gen1 hub and fully compliant with USB-IF's USB3.2 Gen1 specification. The USB5926C also supports Hi-Speed (HS), 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.
**This "C" version contains the latest silicon. All new USB5926 designs should move to this newer "C" version.**
Microchip SmartHub's are defined as USB hubs that integrates system levels functions typically associated with a separate MCU or processor. The USB5926C SmartHub enables communication to other peripherals in addition to USB. The USB5926C's I/O Bridging capability allows the host to seamlessly interface to peripherals via I²C, SPI or GPIOs over USB. The USB5926C also enable a downstream device to take control of the host system by swapping roles and becoming the host port. USB5926C based systems 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 USB5926C 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.
MPLAB® Connect Configurator, Microchip’s proprietary software utility, can be used to program on-chip, One Time Programmable (OTP) ROM for the USB5926C 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 USB5926C can be configured through a series of external low-cost resistor bootstraps. A handful of bootstrap pins are available on the USB5926C to enable standard configurations for GPIOs and downstream ports. No OTP programming required.
