Safety Information
The CY4521 EZ-PD™ CCG2 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 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 CY4521 EZ-PD CCG2 EVK as shipped from the factory has been verified to meet with requirements of CE as a Class A
product.
The CY4521 EZ-PD CCG2 Evaluation Kit 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 CY4521 EZ-PD CCG2 Evaluation Ki 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.

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 CY4521 EZ-PD CCG2 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 CY4521 EZ-PD™ CCG2 Evaluation Kit (EVK) is based on the CCG2 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 platform
to evaluate other features of Type-C such as SuperSpeed USB and DisplayPort data transfer.

The CCG EVK base board consists of a DC input, a USB Type-C Redriving Switch IC, a DisplayPort input, a SuperSpeed
Type-B port, and one Type-C port. The CCG2 daughter card consists of the CCG2 device and a USB-Serial IC to provide a
USB interface for debugging and programming. The CC lines of the CCG2 device are connected to the Type-C port. The USB
Type-C Redriving Switch IC is controlled by the CCG2 device over an I2C interface.
The CY4521 EZ-PD CCG2 EVK has power provider and consumer path control circuitry to showcase EZ-PD CCG2’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 CCG2 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
DisplayPort 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 USB-
PD interface and a daughter card interface connector to connect the CCG2 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 USB Type-C Redriving Switch controlled by the CCG2 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 CCG2 device. This CCG EVK base board along with the CCG2
daughter card helps to convert any desktop or notebook PC with legacy USB ports to operate as a Type-C USB host.

Power
The 24V input provided to the hardware is converted into the voltage to be provided on
the Type-C port using a PMIC. The output voltage of the PMIC is controlled by CCG2.
Power can also be consumed from Type-C connector for dead battery functionality.
Note: The DC power adapter provided with the kit can support only up to 2.7A (at 24 V).
This kit will not work with 5V DC power adapters.
