VCC_USB_LDO

Input

Power supply pin for USB LDO regulator

VCC_USB

I/O

Input: Power supply pin for USB transceiver.

Output: USB LDO regulator output pin. This pin should be connected to an

external capacitor.

USB_DP

I/O

D+ I/O pin of the USB on-chip transceiver. This pin should be connected to

the D+ pin of the USB bus.

USB_DM

I/O
