Title:
USB-to-SPI Bridging with Microchip USB72xx Hubs
Name:
AN3020
Date:

Author:
Shiva Balasubramanian
Description:
The USB-to-SPI bridging feature of Microchip USB hubs provides system designers with 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 USB7202, USB7250, USB7251, USB7252 and USB7256.
