The CP210x has a EEPROM on the chip which can be programmed via USB. The CP210x is an USB-to-serial chip used in a lot of USB devices (similar to FTDIs and PL2303). (uses default settings if OTPROM is empty) Supports USB to RS232 Serial UART Interface o Full-duplex transmitter and receiver (TXD and RXD). O For writing and storing customer USB VID/PID, Serial Number, Product String, and other device startup configurations. ![]() Integrated OTPROM (One-Time Programming ROM) – no external EEPROM required. A software tool called 'EEPROM Writer Program' is available to program this EEPROM through the PL2303 itself, but I cannot find this tool anywhere. The problem is that no information is available about the contents of this EEPROM. ![]() If an external EEPROM is connected, a custom VID/PID can be set.
