Peripheral USB[edit | edit source]
Universal Serial Bus (USB) is an industry standard that establishes specifications for cables and connectors and protocols for connection, communication and power supply (interfacing) between computers, peripherals and other computers.
Description[edit | edit source]
The two USB interface available on ORCA are based on iMX8MPlus SoC.
Each USB 3.0-compliant serial interface port supports the following standards and features:
- Complies with USB specification rev 3.0
- USB dual-role operation and can be configured as host or device
- Super-speed (5 Gbit/s), high-speed (480 Mbit/s), full-speed (12 Mbit/s), and low-speed (1.5 Mbit/s) operations
VBUS detection[edit | edit source]
On the ORCA external connector the USBx_VBUS pins are present to detect that the USB is enabled end therefore power the internal USB PHY.
These pins has a thresold of 4.6V and can accept up to 25V so a direct connection to the USB port VBUS is allowed, even when Power Deliver handshake sets the USB3.0 VBUS to the highest value of 20V.
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
