The CP2102 USB to UART Bridge driver you can download below. Silicon Labs who manufactures the CP2102 chipset has stated that this chip should not be used in new designs and to look at other options. The CP2102N is now the recommended chipset instead of the CP2102 which they also make. The drivers for the CP2102 USD to UART bridge are royalty free and it is plug and play compliant.
CP2102 USB to UART Bridge Driver
The CP2102 USB to UART is a plug and play compliant and are also USB 2.0 compliant. You can also see other drivers for the UART such as the FT232r USB UART driver as well as the FT232R USB UART which you will also find on this website.
This article covers the CP2101, CP2102, CP2103, CP2104, CP2105 and CP2108 USB to UART bridge devices. This will show you how to obtain the port number of a specific CP210X device be this the CP2102 or any other devices in this range of bridges. Note that the vendor ID (VID), product ID (PID) and serial number determine the port number of the device.
The CP2102/9 USB-to-UART Bridge Controller allows you to update RS232 designs to USB using minimum components and PCB space. The CP2102/9 also includes a USB 2.0 full-speed function controller as well as a USB transceiver, oscillator, the EEPROM or in some cases the EPROM, as well as an asynchronous serial data bus (UART) with full modem control signals.
With the on-chip programmable ROM you can also customise the USB Vendor ID, Product ID as well as the Product Description String, Power Descriptor, Device Release Number, as well as the Device Serial Number. This can be changed and programmed via the USB connection from your computer. This is the easiest way to setup and test the CP2102 USB to UART Bridge device. See the cp2102 driver listed below.
In most cases you will not need to change or modify the existing system firmware as the CP2102/9 UART interface implements all RS-232 signals which includes control and handshaking signals. You can download the cp2102 driver listed below.
