STM8 vs Cortex-M0/0+ in a new project

[carlosdelfino]

I am studying a project that requires a very small microcontroller. It will only drive analog and digital ports, but we need the I2C protocol and maybe even CAN. I was advised to use the STM8, but I am not comfortable with this choice. And I wanted to adopt something that was Cortex-M0.

What would be better? The STM8 or an STM32F0 or even another Cortex-M+. What is the future of the STM8 family?

Would it be advisable to mix architectures in a new project?

STM32C0 is now the recent low budget/low feature line to concure against 8 bit. My opinion: If you intende to do rally high numbers, maye STM8 will be cheaper. But on 32 bit , programming is easier and so the startup/. development cost . You must know your boundary conditions...
