4. Customizing Device Descriptors and Other Configurable Options

The descriptors and other configurable options of the devices in the CP210x/CP211x families are modifiable using

the following Windows programs.

These programs are included in the software zip file in this application note. How to use these programs is

described in more detail in the following sections.

CP210xSetIDs uses the Windows Host API functions implemented by CP210xManufacturing.DLL. The Host API

functions give read/write access to the descriptors contained in programmable areas of a connected device.

Another option is implementing a custom application using the Host API and CP210xManufacturing.DLL suited to

the individual needs of a particular production environment.

Both CP2110SetIDs and CP2112SetIDs use the SLABHIDDevice.dll and the customization interface specified in

their respective application notes, “AN433: CP2110 HID to UART API Specification” and “AN496: CP2112 HID

USB to SMBus API Specification”.

The descriptors can also be set in the factory at production time for large orders. Contact your Silicon Laboratories

sales representative for details.
