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.
Table 1. Device Customization Programs
Device
CP2101/2/3/4/5
CP2110
CP2112
Program
CP210xSetIDs.exe
CP2110SetIDs.exe
CP2112SetIDs.exe
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.
