Not sure what you mean by "this price point" but CH32V003 is RISC-V and around 10 cents. It is only 6 times more expensive.

Yeah, that's a savage bastard too. 48MHz, DMA, UART, I2C, SPI, a sleep mode ... 16KB flash and 2KB ram. Certainly enough to run something with a UI, probably enough to implement a basic software defined radio, could probably do some neat tricks when buried inside a USB cable.

I mean, clearly we're at the "splash the cash" end of the Chinese processor market here but at least you get good bang for buck.
