Safety Information

The CY4533 EZ-PD™ Barrel Connector Replacement (BCR) Evaluation Kit (EVK) is intended for use as an evaluation 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 CY4533 EZ-PD BCR EVK board contains 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 CY4533 EZ-PD BCR EVK 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 board provided with CY4533 EZ-PD BCR EVK is sensitive to ESD. Hold the board only by the edges. After removing the 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.

Do’s and Don’ts

Maximum current that can be consumed by an external load connected to the EVK board cannot exceed 5A.

1. Introduction

The CY4533 EZ-PD™ Barrel Connector Replacement (BCR) Evaluation Kit (EVK) is based on the BCR product in Cypress’ USB Type-C and Power Delivery controllers. This EVK is intended to be an evaluation vehicle for applications that would want to consume power over a USB Type-C Connector.

A device, such as a speaker, shaver, power tools, modem etc. that use a barrel connector for power will benefit from using a universal power interface such as USB Type-C. To make the transition easier, the CY4533 EVK provides a USB Type-C receptacle to consume power from a charger and then supply it over a terminal block. A barrel connector can be attached to this block using wires to convert a barrel input to USB Type-C.

1.1 Kit Contents

The CY4533 EZ-PD BCR EVK consists of the following:

 CY4533 EZ-PD BCR EVK Board  Quick Start Guide

1.1.1 Hardware Not Included with the Kit

The CY4533 EZ-PD BCR EVK does not come with all the hardware required to perform the demonstrations mentioned in Kit Operation. The following items are not included:

 A USB Type-C Power Adapter that can supply power over the Type-C port  A two-wire cable with a barrel plug to supply power to an existing device  A device that accepts power from a barrel input  USB-C cable required (if not already provided with the USB-C Power Adapter) for connecting the USB Type-C power

adapter to the Type-C receptacle on the EVK

 Multimeter and other measurement equipment  A 3 mm flat head screw driver (for turning the SW1 rotary switch knob)  A wire stripper  CY4500 EZ-PD Protocol Analyzer

1.2 Getting Started

For instructions on how to run a quick demonstration and observe the kit functionality, see the Kit Operation section.
