Safety Information

The CY4531 EZ-PD CCG3 Evaluation Kit Guide boards contain ESD-sensitive devices.
Electrostatic charges readily accumulate on the human body and any equipment, which can cause
a discharge without detection. Permanent damage may occur to devices subjected to high-energy
discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of
functionality. Store unused CY4531 EZ-PD CCG3 Evaluation Kit Guide boards in the protective
shipping package.

End-of-Life/Product Recycling
The end-of-life cycle for this kit is five years from the date of manufacture mentioned on the back of

the box. Contact the nearest recycler to discard the kit.

The CY4531 EZ-PD™ CCG3 EVK is intended for use as a development platform for hardware or software in a laboratory
environment. The board is an open-system design, which does not include a shielded enclosure. Due to this reason, the
board may cause interference to other electrical or electronic devices in close proximity. In a domestic environment, this
product may cause radio interference. In such cases, take adequate preventive measures. Also, do not use this board near
any medical equipment or RF devices.

Attaching additional wiring to this product or modifying the product operation from the factory default may affect its
performance and cause interference with other apparatus in the immediate vicinity. If such interference is detected, suitable
mitigating measures must be taken.

The CY4531 EZ-PD CCG3 EVK as shipped from the factory has been verified to meet with requirements of CE as a Class
A product.

Safety Information

General Safety Instructions

ESD Protection

ESD can damage boards and associated components. Cypress recommends that the user perform procedures only at an
ESD workstation. If an ESD workstation is not available, use appropriate ESD protection by wearing an antistatic wrist strap
attached to the chassis ground (any unpainted metal surface) on the board when handling parts.

Handling Boards

The boards provided with CY4531 EZ-PD CCG3 Evaluation Kit are sensitive to ESD. This also applies to the boards that
are provided with a plastic casing when they are removed from the casing. Hold the boards only by the edges. After
removing a board from the box/casing, place it on a grounded, static-free surface. Use a conductive foam pad, if available.
Do not slide the board over any surface.

1. Introduction

The CY4531 EZ-PD™ CCG3 Evaluation Kit (EVK) is based on the CCG3 product family of Cypress’s USB Type-C
microcontrollers. This EVK is primarily intended to be an evaluation vehicle for USB Type-C host and client systems that
house a Type-C connector as well as for notebook applications. For USB Power Delivery (PD), the base board and
daughter card can be configured as a downstream facing port (DFP) or an upstream facing port (UFP). The kit also serves
as a vehicle to evaluate several features for Type-C, using a SuperSpeed USB demo and a DisplayPort demo, as
examples.

1.1 Kit Contents

The CY4531 EZ-PD CCG3 EVK consists of the following contents:

 CCG EVK Base Board
 CY4531 CCG3 Daughter Card (mounted on CCG EVK Base Board)
 24-V DC 65 W Power Adapter (24 V, 2.7 A)
 USB 3.0 Type-A to Type-B cable
 USB Type-C to Type-A adapter
 USB 3.1 EMCA (Electronically Marked Cable Assembly) Type-C cable
 USB 2.0 Type-A to Mini-B Cable
 Quick Start Guide

1.1.1 Hardware Not Included With Kit

The CY4531 EZ-PD CCG3 EVK does not come with all of the hardware needed to perform the demonstrations documented
in sections SuperSpeed USB Demo, DisplayPort Demo, and Dead Battery Demo of the Kit Operation chapter. The following
items are not included:

 USB flash drive needed for the SuperSpeed USB Demo section.
 DisplayPort cables needed for the DisplayPort Demo section. They are required to make connections from a PC to the

CCG EVK base board. If the PC has a mini-DisplayPort, then a mini-DisplayPort to DisplayPort cable will be required. If
the PC has a DisplayPort, then a DisplayPort to DisplayPort cable will be required. Recommended cables are listed in

Recommended Cables and Adapters section.

 USB Type-C to DP/HDMI/VGA adapter to connect a display monitor to the CY4531 EZ-PD CCG3 EVK. Recommended

adapters and cables needed for them to connect to monitors are listed in Recommended Cables and Adapters section.

 A digital multimeter to measure voltage for the Dead Battery Demo section. A standard multimeter is required to

measure the output voltage on the CCG base board to successfully demonstrate dead battery functionality along with a
USB Type-C Power Adapter.

The CY4531 EZ-PD CCG3 EVK consists of a base board and a daughter card. The CCG3 device is mounted on the
daughter card, which is connected to the base board to evaluate the CCG3 device’s Type-C port functionality as shown in

Figure 3-1.

Figure 3-1: CY4531 EZ-PD CCG3 EVK Architecture

The CCG base board consists of a DC input power supply, a Display multiplexer, one Display port, a SuperSpeed Type-B
port, and one Type-C port. The CCG3 daughter card consists of the CCG3 device and a USB-Serial IC to provide a USB
interface for debugging and programming. The CC lines of the CCG3 device are connected to the Type-C port. The Display
multiplexer is controlled by the CCG3 device over an I2C interface.

The CY4531 EZ-PD CCG3 EVK has a power provider and consumer path control circuitry to showcase EZ-PD CCG3’s
ability to switch its power role from a provider to a consumer and vice versa. This EVK has over-voltage and over-current
protection circuitry for VBUS and it also supports programming of the EZ-PD CCG3 device over SWD and I2C interfaces.
The EVK supports PCs, notebooks, tablets, and other applications that would host a Type-C interface. It is primarily
intended as an evaluation vehicle for USB host systems that house a Type-C connector.

3.1 CCG EVK Base Board

The CCG EVK base board is an evaluation board equipped with a Type-C port, a SuperSpeed USB Type-B port, and a
Display Port interface. It is primarily intended as a demonstration board for notebook designs that house a Type-C
connector. The board also serves as a vehicle to evaluate the alternate modes for Type-C, using the DisplayPort demo as
an example.

3.1.1 Block Diagram

The block diagram of the CCG EVK Base board is shown in Figure 3-2. It has an on-board Type-C connector for the USB­PD interface and a CCG3 daughter card interface connector to connect the CCG3 daughter card. It also includes a
SuperSpeed USB Type-B port, and a Display Port connector to source video. The SuperSpeed USB signals and Display
Port signals are connected to the Type-C connector through a high-speed multiplexer controlled by the CCG3 device. A DC
power adapter provides input voltage to the onboard Power Management IC (PMIC). The output voltage from the PMIC can
be selected using two voltage selection lines, controlled by the CCG3 device. This CCG base board along with the CCG3
daughter card helps to convert any desktop or notebook PC with legacy USB ports to operate as a Type-C USB host.
