Question

How do I customize a CP2615 on a board I designed?

Answer

To customize a CP2615 during development and prototyping, Xpress Configurator is the recommended GUI tool.

In a production setting, the Standalone Manufacturing Tool is an available command line tool for Windows, Mac and Linux. For more information about the Standalone Manufacturing Tool, see Application Note AN721: USBXpress Device Customization Guide.

To customize a CP2615, Xpress Configurator and the Standalone Manufacturing Tool require a CP2112 USB-to-I2C bridge, and the CP2112's PID must be 0xEA93. See the following connection diagram.

An example, showing a CP2112-EK connected to a CP2615-EK for programming is shown here:

By default, the CP2112 PID is 0xEA90. To change the PID of a CP2112, use Xpress Configurator and refer to Application Note AN721: USBXpress Device Customization Guide.

In addition to changing the PID to 0xEA90, you must also change the CP2112's serial string to a value that Simplicity Studio has not seen before, since Simplicity Studio caches device configuration by serial number. For example, in this instance, a CP2102 has previously been plugged in and detected by Simplicity Studio with the serial string '0001'. When the CP2112 is re-programmed with a serial string of '0001', it now appears as a CP2102, instead:

If the serial number remains the same as the default, or if it is the same as a previously connected CP210x device, the device will still appear as the previously connected device with the same serial number (instead of a CP2615 programmer). If this occurs, you can clear Simplicity Studio's device cache by navigating to C:\Users[USERNAME]\SimplicityStudio\v4_workspace\.metadata\.plugins\com.silabs.ss.platform.device.core\device and deleting all .info devices there.

You can also switch to a different workspace to resolve the issue.

Once the CP2112 is programmed with the PID of 0xEA93 (and new serial string), it may first appear as an "Unknown Device" within Simplicity Studio, if the device is not able to communicate with a CP2615.

Once a CP2615 is connected, Simplicity Studio will then properly detect the CP2112 as a CP2615 programmer, and it will be available as a programming option in Xpress Configurator.

Note: A CP2112 with PID 0xEA93 is included on the CP2615 Evaluation Board. Therefore, the CP2615 on the CP2615 Evaluation Board is ready for customization by Xpress Configurator and the Standalone Manufacturing Tool.

Note: When using the CP2112 on the CP2615 Evaluation Kit to program a CP2615 on a custom board, remove the shorting blocks on J13, J14, J15, and J16.
