9. CP2103 Device Drivers

There are two sets of device drivers available for the CP2103 devices: the Virtual COM Port (VCP) drivers and the

USBXpress Direct Access drivers. Only one set of drivers is necessary to interface with the device.

The latest drivers are available at http://www.silabs.com/products/microcontroller/downloads.asp.

9.1. Virtual COM Port Drivers

The CP2103 Virtual COM Port (VCP) device drivers allow a CP2103-based device to appear to the PC's

application software as a COM port. Application software running on the PC accesses the CP2103-based device

as it would access a standard hardware COM port. However, actual data transfer between the PC and the CP2103

device is performed over the USB interface. Therefore, existing COM port applications may be used to transfer

data via the USB to the CP2103-based device without modifying the application. See Application Note AN197:

Serial Communications Guide for the CP210x” for Example Code for Interfacing to a CP2103 using the Virtual

COM drivers.

9.2. USBXpress Drivers

The Silicon Laboratories USBXpress drivers provide an alternate solution for interfacing with CP2103 devices. No

Serial Port protocol expertise is required. Instead, a simple, high-level application program interface (API) is used

to provide simpler CP201x connectivity and functionality. The USBXpress for CP210x Development Kit includes

Windows device drivers, Windows device driver installer and uninstallers, and a host interface function library (host

API) provided in the form of a Windows Dynamic Link Library (DLL). The USBXpress driver set is recommended

for new products that also include new PC software. The USBXpress interface is described in Application Note

“AN169: USBXpress Programmer's Guide.”

9.3. Driver Customization

In addition to customizing the device as described in Section 7, the drivers and the drivers installation package can

be also be customized. See Application Note “AN220: USB Driver Customization” for more information on

generating customized VCP and USBXpress drivers.

9.4. Driver Certification

The default drivers that are shipped with the CP2103 are Microsoft WHQL (Windows Hardware Quality Labs)

certified. The certification means that the drivers have been tested by Microsoft and their latest operating systems

(XP and Vista) will allow the drivers to be installed without any warnings or errors.

The customized drivers that are generated using the AN220 software are not automatically certified. They must go

first through the Microsoft Driver Reseller Submission process. Contact Silicon Laboratories support for assistance

with this process.
