ElectroNex:
im looking for an stm32 chip that can do 3 i2C connections, usb-c, 3 UART, 65 I/O's minimum and a 512kb program storage size, has to be suitable for new designs and smd :-+ :-+ :-+

Beware, this poster has previously started a very similar thread which got 6 replies, but OP didn't respond at all.

Prepare to be stonewalled if posting here :P

Doctorandus_P:
I recommend you buy a stm32 chip with at least 3 i2C connections, usb-c, 3 UART, 65 I/O's minimum and a 512kb program storage size, and suitable for new designs and smd

Also, what does "USB-C" have to do with your uC? It's just a mechanical connector, and it is supposed to be used with many different signalling protocols.

I think you can choose  STM32F767. It has 4 I2C interfaces and 4 UARTS, 512KB SRAM. No. of I/O pin is also matching with what you want: https://www.st.com/resource/en/datasheet/stm32f765bi.pdf

You can make multi-channel data loggers like this with STM32F4 MCUs:

If you use STM32F767 in such projects, it can more advanced.
