Cheapest STM32 that can simultaneously do USB as a Host and Device.

[DKasp.1]

Hey all! Does anyone know the cheapest option for a STM32 chip that can simultaneously do USB as a Host and as a Device? I tried using the product selector but the issue is that it didn't list price as a filter option, so I thought I would ask here.

I'm making a very simple piece of hardware (a keyboard plugged into one end of the device and some software to convert it into a game controller, outputted on the other side.) Does anyone have any recommendations for a STM32 chip (or other ST chips) that can do just that? (Bonus points if it's one of the cheapest that can do just that!)

I already have this project running on an Arduino with some shields, but would like to bring it to production though. Experimented with some FTDI chips but they unfortunately had one flaw that blocked development.

Thanks!

Which product selector did you try?

The one integrated in STM32CubeMX can filter and sort by price.
