The hard processor system (HPS) provides two instances of a USB On-The-Go (OTG) controller that
supports both device and host functions. The controller supports all high-speed, full-speed, and low-speed
transfers in both device and host modes. The controller is fully compliant with the On The Go and
Embedded Host Supplement to the USB Revision 2.0 Specification. The controller can be programmed for
both device and host functions to support data movement over the USB protocol.
The controllers are operationally independent of each other. Each USB OTG controller supports a single
USB port connected through a USB 2.0 Transceiver Macrocell Interface Plus (UTMI+) Low Pin Interface
(ULPI) compliant PHY. The USB OTG controllers are instances of the Synopsys
USB 2.0 Hi-Speed On-The-Go (DWC_otg) controller.
The USB OTG controller is optimized for the following applications and systems: †
• Portable electronic devices †
• Point-to-point applications (no hub, direct connection to HS, FS, or LS device) †
• Multi-point applications (as an embedded USB host) to devices (hub and split support) †
Each of the two USB OTG ports supports both host and device modes, as described in the On The Go and
Embedded Host Supplement to the USB Revision 2.0 Specification. The USB OTG ports support connections
for all types of USB peripherals, including the following peripherals:
• Mouse
• Keyboard
• Digital cameras
• Network adapters
• Hard drives
• Generic hubs
