3. Kit Operation
The CY4502 CCG2 DVK includes the CY4502 board shown in
Figure 3-1. CY4502 Board
This DVK contains two CCG2 controllers (one in the CSP package and the other in the DFN package), two SWD
connectors, two USB Type-C plugs, two LEDs, and footprint to populate a 20-pin header for debugging. The SWD
connectors can be used to update the firmware on the CYPD2103 devices. Type-C plugs serve as connectors at either
end of the cable, providing a way to connect to the Type-C receptacle at the downstream facing port (DFP) and upstream
facing port (UFP). Test points are exposed in the 20-pin header, which includes CCG2 GPIOs, I
2
C lines, termination
resistor R
D
, VCONN, and the CC lines. LEDs are used to indicate the powered chip.
The two CYPD2103 devices in the CY4502 board are shipped with factory-programmed firmware that demonstrates the
functionality of CCG2 controllers in EMCA USB PD Type-C cables. The CYPD2103 firmware implements a passive EMCA
cable with one CCG2 controller or two CCG2 controllers for each cable solution.
3.1 Theory of Operation
This DVK can be used to emulate a general-purpose cable with a USB Type-C plug at each end, as shown in
The DVK can be configured to operate in one of three supported passive cable configurations: (1) a chip at only one end of
the cable; (2) a chip at each end of the cable where only one is powered at a time; (3) a chip at each end of the cable
where both are powered simultaneously. The next section covers the jumper settings required to test various
configurations
