USB Power Delivery specification introduces USB Type-C receptacle, plug and cable; they provide a
smaller, thinner and more robust alternativ e to existing USB interconnect. Main features are:
•Enable new and exciting host and device form-factors where size, industrial design and style are
important parameters
•Work seamlessly with existing USB host and device silicon solutions
•Enhance ease of use for connecting USB devices with a focus on minimizing user confusion for
plug and cable orientation

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

USB PD Stack & Policy
Policies
System Policy Manager (system
wide) is optional. It monitors and
controls System Policy between
various Providers and Consumers
connected via USB.
Device Policy Manager (one per
Provider or Consumer) provides
mechanisms to monitor and control
the USB-PD within a particular
Provider or Consumer. It enables
local policies to be enforced across
the system by communication with
the System Policy Manager.
Policy Engine (one per Source or
Sink Port) interacts directly with the
Device Policy Manager in order to
determine the present local policy
to be enforced.

Physical Layer
Protocol Layer
The Protocol Layer forms the messages
used to communicate information between a
pair of ports. It receives inputs from the
Policy Engine indicating which messages to
send and indicates the responses back to
the Policy Engine
Physical Layer
It is responsible for sending and receiving
messages across either the V
wire. It consists o f a transce i v er th at
superimposes a signal (BFSK on V
BMC on CC) on the wire.
It is responsible for managing data on the
wire and for collision avoidance and detects
errors in the messages using a CRC
