Evaluation Tools The Re-evolution of USB 3
USB has evolved from a data interface capable of supplying limited power to a primary provider of power with a data interface
USB Power USB Alternate Type-C Delivery Data Mode
A smart and green technology • More flexibility with a new reversible & thinner connector, more robust • More power with USB Power Delivery (up to 100W) • More speed with USB 3.1 (5/10Gbps), USB 3.2 (20Gbps), USB4 (40Gbps) • More protocols (Display Port, HDMI, Thunderbolt 3, …) Power, Data & Display: All-in-One interface 4
Power management High Speed Data Display Connection 100W max USB 2.0 Video + Audio USB 3.x (DisplayPort™ or HDMI™)

Enhance ease of use
Receptacle
Two pins on the USB Type-C receptacle, CC1 and CC2, are used in the discovery, configuration and management of connections across the USB Type-C cable
Plug
On a standard USB Type-C cable, only a single CC wire within each plug is connected through the cable to establish signal
orientation. 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)

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

• 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, ...
