Introduction
Hardware development phase:
Select a CMG2-based cable application (one-chip/cable or two-chip/cable), review the reference designs, and
start the hardware development phase of the design flow.
The hardware flow includes building schematics based on the end application and doing the paddle card
design to get a few prototypes ready for the next phase.
Configuration and testing phase:
This phase requires a CY4532 EZ-PD™ CCG3PA EVK power board and USB EZ-PD™ Configuration Utility with MTK
support.
CY4532 EZ-PD™ CCG3PA EVK power board is used to read/flash the configuration of CMG2.
USB EZ-PD™ Configuration Utility is used to create a configuration file (.CYACD) for the CMG2 device of the
EMCA cables (.CYACD contains vendor IDs, DISC_ID, DISC_SVID, and DISC_MODES configuration). Once a
configuration has been created, the CMG2 MTK utility included in the EZ-PD™Configuration Utility is used for
configuring (i.e., programming) and testing the designed cables. Up to 10 cables can be configured and tested
simultaneously using the MKT utility. More information on the CMG2 MTK utility can be found in Chapter 4
(section 4.9) of the EZ-PD™ Configuration Utility user manual.
Once the hardware, configuration, and test flows are completed, the system design is ready for mass
production.

2.1 CY4532 EZ-PD™ CCG3PA EVK
The CY4532 EZ-PD™CCG3PA EVK supports mobile power adapters, PC power adapters, power banks, car
chargers, and other applications that primarily charge other devices via a Type-C interface. The kit is intended
as an evaluation vehicle for USB host systems that house a Type-C connector. See the CY4532 EZ-PD™ CCG3PA
EVK user guide for in-depth information about EVK use cases.
The CY4532 EZ-PD™ CCG3PA EVK consists of a power board and a main board. The CCG3PA device is mounted
on the main board, which is connected to the power board to enable the CCG3PA device’s Type-C port
functionality.
For the CMG2 MTK test setup, the CY4532 EZ-PD™ CCG3PA EVK main board is not discussed further in this
section, and only the CY4532 EZ-PD™ CCG3PA EVK power board is covered.

2.2 CMG2 MTK hardware setup
As shown in Figure 4, a PC running the EZ-PD™Configuration Utility is connected to a CY4532 EZ-PD CCG3PA
EVK power board using a Type-A to Type-B Micro-B USB cable. The CMG2-based passive EMCA cable is
connected to the Type-C receptacle of the CY4532 EZ-PD™CCG3PA EVK power board.
The CMG2 MTK utility is included with the EZ-PD™ Configuration Utility. It can configure and test up to 10 CMG2-
based passive EMCA cables in parallel. In cases where it is required to configure and test more than one CMG2-
based passive EMCA cable at once, a SuperSpeed hub must be connected, as shown in Figure 5.

configuration and testing
This section provides an overview of using the EZ-PD Configuration Utility and the included CMG2 MTK Utility
with CMG2 based EMCA cables. CMG2 devices contain 47 bytes of NVL, which is used for storing configuration
data. Because no firmware development is necessary (as CMG2 is a ROM-based part), CMG2 devices are not
supported in any other Infineon tools such as PSoC™ Creator or PSoC™ Programming Solutions.
3.1 EZ-PD™ Configuration Utility and CMG2 MTK utility
The EZ-PD™ Configuration Utility is a Windows application that configures parameters stored in the
configuration table areas of the internal flash memory of a CCGx device. Version 1.4.0 (or later) integrates and
supports the CMG2 MTK utility. Vendor-specific and cable-specific parameters can be set using the EZ-PD™
Configuration Utility.
After setting the parameters, use the CMG2 MTK utility to configure and test CMG2-based passive EMCA cables.
The CMG2 MTK utility is accompanied by a CMG2 MTK-specific firmware solution intended for the CCG4 device
present on the CY4532 EZ-PD™ CCG3PA EVK power board. A high-level block diagram of how the CMG2 MTK
utility communicates with the CMG2-based passive EMCA cable is shown in Figure 6.

The CCG4 device-based CMG2 MTK-specific firmware implements a unique application ID for the EZ-PD™
Configuration Utility to run the MTK-based firmware. It allows the CMG2 MTK utility to detect connected CMG2-
based passive EMCA cables once it receives MTK configuring initiation commands.
You can download and install the EZ-PD™ Configuration Utility containing the CMG2 MTK utility from the USB
EZ-PD™ Configuration Utility page. Figure 7 shows the start page of the utility.

4Example showing the configuration and test of a CMG2-based
passive EMCA cable
Configuring and testing CMG2-based EMCA cables using the CMG2 MTK utility involves four steps:
1. Update the firmware of the CCG4 device (MTK firmware path is available in Section 4.1.1 step 8) on the
CY4532 EZ-PD™ CCG3PA EVK power board and configure an MTK tester ID (perform this step only once in the
complete process of configuring the CMG2-based EMCA cables).
2. Connect the CMG2-based passive EMCA cable with the necessary hardware (CY4532 EZ-PD™ CCG3PA EVK
power board) and a PC running the EZ-PD™ Configuration Utility.
3. Create and save a configuration file (CYACD format) for the connected CMG2-based passive EMCA cable
using the EZ-PD™ Configuration Utility.
4. Configure and test the connected CMG2-based passive EMCA cable using the CMG2 MTK utility.
4.1 Update the firmware of the CCG4 device on CY4532 EZ-PD™ CCG3PA EVK
and configure MTK tester ID
Updating the firmware of the CCG4 device enables the EZ-PD™ Configuration Utility running on the host PC to
communicate with a CMG2-based passive EMCA cable connected to the CY4532 power boards; see Figure 6. You
also need to set up a unique MTK tester ID for the CCG4 device to help identify each MTK hardware uniquely.
4.1.1 Updating the firmware of the CCG4 device
1. Download and install EZ-PD™ Configuration Utility (v1.4.0 or later) that supports the CMG2 MTK utility.
2. On the CY4532 EZ-PD™ CCG3PA EVK, carefully unmount the CCG3PA main board from the power board.
3. Remove the shunts on jumpers J6, J7, and J9 of the CY4532 EZ-PD™ CCG3PA EVK power board as follows:

7. In the new window that pops up, provide the file location of the firmware that needs to be programmed in
the CCG4 device. If the folder selected in step 1 was the default location of “C:\Infineon”, then the required
firmware is in the following local directory: “C:\Infineon\Tools\EZ-PD Configuration Utility\Firmware\MTK”
8. Select NOTEBOOK from the target list shown in Figure 11, click Browse next to the Firmware path 1 text
field, and browse to the local directory where EZ-PD™ Configuration Utility was installed. Next, double-click
the CYPD4126-40LQXI_mtk_1.CYACD file to select it. Similarly, select the CYPD4126-40LQXI_mtk_2.CYACD file
for Firmware path 2.
Note: Two CYACD files are required for programming the CCG4 device because the CCG4 device flash
is organized in two 64-KB banks each with a separate copy of the firmware.
