USB-to-SPI Bridging with Microchip USB7002 and USB705x Hubs
The USB-to-SPI bridging feature provides system designers who use Microchip hubs an expanded system control and a potential BOM reduction. The use of a separate USB-to-SPI device is no longer required, and a downstream USB port is not lost as a result of implementing the standalone USB-to-SPI device. This feature is available on Microchip hubs that contain an internal Hub Feature Controller (HFC) and a Serial Peripheral Interface (SPI) interface. These hubs include USB7002, USB7050, USB7051 USB7052, and USB7056.
