stm32 with 8 uarts and a small footprint

[Evan .1]

I'm searching for a stm32 with 8 uarts for io-link. But there is no way I can search for peripherals. So any suggestions, preferably in LQFP-48 or something similar small.

Thanks.

It's like three or four clicks away from ST's main page. How hard this can be to find?

You can also sort the product selector table by the UART/USART columns. A bit cumbersom that they are split, and there's no product selector table for the main STM32 page so you have to go to one of the three or four subpages, but that's hardly an obstacle.

I believe there's also something like this in CubeMX (I don't Cube) and there's also a standalone selector application I'm not going to search it for you.

I don't know every STM32 variant, but quite a lot.

But there is no one with 8 UARTs I know of. Maximum I came across is 6.

There seems no use case for ST worth to produce such an MCU as silicon.

But you can try ST's "MCU Finder": https://www.st.com/en/development-tools/st-mcu-finder.html

Ah yes that's that selector application, thanks Ozone.

Ok thanks. This seems the answer: STM32F091RCT7
