EZ-PD™ CCG4 is a dual USB Type-C controller that complies with the latest USB Type-C and PD standards. EZ-PD CCG4 providesa complete dual USB Type-C and USB-Power Delivery port control solution for notebooks, power adapters and docking stations. Itcan also be used in dual role and downstream facing port applications. EZ-PD CCG4 uses Cypress’s proprietary M0S8 technologywith a 32-bit, 48-MHz ARM® Cortex®-M0 processor with 128 KB flash and integrates two complete Type-C Transceivers including theType-C termination resistors RP and RD.

EZ-PD™ CCG4 is Cypress’s newest USB Type-C port controller with Power Delivery. CCG4 provides a two-port USB-C solution ideal for Desktops, Notebooks and Systems like Power Banks, Monitors and Docks. CCG4 is based on Cypress’s PSoC technology with 128KB flash memory supporting fail-safe boot up. CCG4 supports Upstream Facing Port (UFP), Downstream Facing Port (DFP), and Dual Role Port (DRP) modes. CCG4 reduces BOM by integrating four 1W VCONN FETs, Over-Voltage and Over-Current Protection and 15kV system level ESD protection.

CY4541 EZ-PD™ CCG4评估套件(EVK)

The CY4541 EZ-PD™ CCG4 Evaluation Kit (EVK) is based on the Cypress’s CCG4 dual port Type-C Power Delivery (PD) controllers. EZ-PD™ CCG4 is a dual USB Type-C controller that complies with the latest USB Type-C and PD standards. This EVK is primarily intended to be a demonstration vehicle for Type-C PC designs that house one or two Type-C ports. CCG4 can act either as a power provider (Source) or as a power consumer (Sink). The kit also helps to evaluate several features on two Type-C ports, using a Dual Role Port (DRP) or SuperSpeed USB demo, and a DisplayPort demo.

CY4541 EZ-PD™ CCG4评估套件(EVK)包括:

Two CCG EVK base boards assembled with one CCG4 daughter card 
One 24-V DC power adapter*
Two SuperSpeed Type-A to Type-B cables
Two Type-C to Type-A dongles 
One Type-C cable* 
One Type-A to Mini-B cable 
One set of jumper wires 
One screwdriver

图7.CY4541 EZ-PD™ CCG4评估套件(EVK)系统框图

The CY4541 EZ-PD CCG4 EVK consists of two CCG base boards and one CCG4 daughter card. The CCG4 daughter card is connected to the two CCG base boards to evaluate the CCG4’s dual Type-C port capability.

The CCG base board consists of a DC input power supply, a display multiplexer, a DisplayPort connector, a SuperSpeed Type-B port, and a Type-C port. The CCG4 daughter card consists of the CCG4 device and a USB-Serial IC to provide aUSB interface for debugging. CCG4‘s CC lines of the respective Type-C interface are connected to the Type-C port on the CCG base board. CCG4 controls the display multiplexer over an I2C interface.

The CY4541 EZ-PD CCG4 EVK has a power provider and power consumer path control circuitry to showcase CCG4’s ability to switch its power role from a provider to a consumer and vice-versa. This EVK has overvoltage and overcurrent protection circuitry for VBUS and VCONN; it also supports programming CCG4 devices over SWD and I2C interfaces. A PC with two USB 3.0 ports and a DisplayPort along with the CY4541 EZ-PD CCG4 EVK is equivalent to a PD-enabled dual Type-C port PC.

The CCG base board has an onboard Type-C connector for the USB-PD interface and a CCG4 daughter card interface connector to connect the CCG4 daughter card. It also includes a SuperSpeed USB Type-B port and a DisplayPort connector to source video. The SuperSpeed USB signals and DisplayPort signals are connected to the Type-C connector through a display multiplexer controlled by the CCG4 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 CCG4. This CCG base board, along with the CCG4 daughter card, helps convert any desktop or notebook PC with legacy USB ports to operate as a Type-C USB host.

The CCG4 daughter card is an evaluation board with a CCG4 controller (CYPD4225-40LQXIT) and a USB-Serial Bridge Controller (CY7C65215) to provide a USB interface for debugging. The CCG4 daughter card must be assembled with the CCG base boards. This complete assembly setup supports Type-C host applications such as PCs.

PD-enabled USB products (such as a PC with a Type-C port) operate as a power provider and a power consumer. The USB PD specification refers to such USB Type-C ports as Dual Role Ports (DRPs).
