The other CC pin is repurposed as V CONN for powering electronics Also, only one set of USB 2.0 D+/D- wires are implemented High Speed Data Path High Speed Data Path USB 2.0 Cable Bus Power Sideband Cable Configuration (RX for USB 3.1, or (TX for USB 3.1, or (from 5V up to 20V) reconfigured in Alternate Mode) reconfigured in Alternate Mode) Interface use Ground Channel USB-C: Host-to-device Connection 9 SOURCE SINK (Host / DFP) (Device / UFP) 4 possible Source Rp wiring Sink Rd Power pull-up pull-dw Legacy current 56 k Ω CC pin 5.1 k Ω 1.5A @ 5V 22 k Ω 3A @ 5V 10 k Ω 1. By default: VBUS is not powered (cold socket) 2. At insertion detect, the Configuration Channel (CC pin) is used to solve plug orientation (CC1 or CC2) • HOST identified by Pull-up resistor / current source on its CC pin • Device identified by Pull-Down resistor on CC pin 3. After correct Host to Device connection, VBUS is supplied as well as Vconn on the unconnected CC pin 4. Optionally, USB PD, Alternate or Accessory Mode can be supported USB-C principle 10 • Source-Only meets Sink-Only SOURCE SINK Host-to-device Connection 11 • Logical Model for Data Bus Routing Implementation without Switch Implementation with Switch USB Power Delivery (USB PD) 12 Key Characteristics • Voltage and Current values are negotiated (via CC pin) • Higher voltage and current: power up to 100W (20V / 5A) • Swapping of power direction, data direction and source of VCONN • Communication with USB Type-C Electronically Marked Cables ( EMC ) • Support for Alternate Modes of operation (DP, MHL, Thunderbolt) • Signaling : • 1-wire communication, bidirectional • Half duplex system • Biphase Mark Coding (BMC) • Bit rate : 300kbps • CRC-32 used to detect data corruption USB Type-C [vs] USB PD 13 • USB-C • Power: 15W max • 5V/3A, 5V/1.5A, 5V/LegacyCurrent • Legacy USB2.0 power: 5V/500mA (after USB enumeration), 5V/100mA (no enumeration) • Power Role: Source, Sink, or Dual Role Power (DRP) • USB-C Power Delivery • PD communication occurs on CC line • Power: 100W max (20V@5A) • VBUS min= 5V ; max= 20V • Several power profiles possible (PDO). e.g.: [5V, 9V, 15V, 20V] • Power Role: Source, Sink, or Dual Role Power (DRP) • PD mode always starts after USB-C attachment is done (i.e. 5V is available on VBUS at this point) • Additional optional features: • Swap of Power Role, Swap of Data Role • Communicate with EMC cables, VDM, authentication, Alternate modes, Firmware update over CC, ...
