USB Type-C PD controller & USB UART bridge
« on: October 24, 2022, 07:11:32 pm »
I'm looking for an IC that offers a USB to UART bridge together with a USB Type-C PD controller. The only chip I've come across so far is the FTDI DT232HPQ, but the datasheet is honestly not that great. From what I can gather an external EEPROM is required for operation in anything but the standard USB PD mode 5V/3A. I'd assume that EEPROM needs to be programmed somehow as well so I'd still need a specialized programmer.

Are there any other chips that offer USB Type-C PD support and a USB to UART bridge? This is for an ESP32 project which would really benefit from a combination of the two. Given how convenient of a solution this is I'd imagine there would be more than one suitable chip on the market.

Do you know of any crowd favorites for this kind of solution?

On the FTDI part: it might be that FTDI offers some PC (Windows/Linux/Mac) software which can program the EEPROM via USB for you. (For the FT230 lineup there’s FT_Prog, which works well enough.)
