Microchip USB5807C/KD

Microchip’s USB5807C SmartHub™ is a 7 port, SuperSpeed (SS), low power, configurable USB3.1 Gen1 hub and fully compliant with USB-IF's USB 3.2 Gen1 specification (TID1595). This supports the latest ECNs for USB-IF logo compliance for the new USB Type-C™ industry initiative. The USB5807C 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 USB5807 designs should move to this newer "C" version.

The USB5807C is also a SmartHub which is defined as a USB hub that integrates system levels functions typically associated with a separate MCU or processor. The USB5807C SmartHub enables a downstream device to take control of the host system by swapping roles and becoming the host port. The SmartHub 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.

The hub also can expand beyond seven ports through PortSplitting which allows for embedded applications to only use the interface needed for internal, non-removable USB connections.

MPLAB^® Connect Configurator, Microchip’s proprietary software utility, can be used to program On-chip One Time Programmable (OTP) ROM 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 USB5807C can be configured through a series of external low-cost resistor bootstraps. A handful of bootstrap pins are available on the USB5807C to enable standard configurations for GPIOs and downstream ports. No OTP programming required.

Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects.
