The OTG_FS is a dual-role device (DRD) controller that supports both device and host
functions and is fully compliant with the On-The-Go Supplement to the USB 2.0
Specification. It can also be configured as a host-only or device-only controller, fully
compliant with the USB 2.0 Specification. In host mode, the OTG_FS supports full-speed
(FS, 12 Mbits/s) and low-speed (LS, 1.5 Mbits/s) transfers whereas in device mode, it only
supports full-speed (FS, 12 Mbits/s) transfers. The OTG_FS supports both HNP and SRP.
The only external device required is a charge pump for V
OTG_FS main features
The main features can be divided into three categories: general, host-mode and device-
mode features.
