8. One-Time Programmable ROM
The CP2104 includes an internal one-time programmable ROM that may be used to customize the USB Vendor ID
(VID), Product ID (PID), Product Description String, Power Descriptor, Device Release Number, Device Serial
Number, GPIO configuration, Suspend pins, and modes as desired for OEM applications. If the programmable
vendor ID can be obtained from www.usb.org or Silicon Labs can provide a free PID for the OEM product that can
be used with the Silicon Labs VID. Customizing the serial number is also recommended if the OEM application is
one in which it is possible for multiple CP210x-based devices to be connected to the same PC.
The configuration data ROM can be programmed by Silicon Labs prior to shipment with the desired configuration
information. It can also be programmed in-system over the USB interface by adding a capacitor to the PCB. If
configuration ROM is to be programmed in-system, a 4.7 F capacitor must be added between the VPP pin and
ground. No other circuitry should be connected to VPP during a programming operation, and VDD must remain at
3.3 V or higher to successfully write to the configuration ROM.
