In the page 18 i.MX8M Mini data sheet <http://nxp.com/doc/imx8mmiec>, it shows min/typ/max operating range of USB1_VBUS are 0.80/1.40/3.60v. In USB standard, VBUS is 5v. So what maximum operating range of USB1_VBUS is support by i.MX8M Mini?

Hi m.c.

datasheet is correct, usb connections are described in sect.3.9.14.1 Pad/Package/Board connections:


The USBx_VBUS pin cannot directly connect to the 5 V VBUS voltage on the USB2.0 link.
Each USBx_VBUS pin must be isolated by an external 30 K 1% precision resistor.
