　　CY4541 EZ-PD™ CCG4评估板(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.
