Raspberry Pi Pico and RP2040 Microcontroller

I bet that future Raspberry Pi boards will have a RP2040 or successor chip onboard, to do the bit banging/realtime jobs on the I/O port.

Or they will even integrate it into their SOC.

Shame though, that they didn't make the IO ports 5V capable. It's nowadays pretty common for microcontrollers that are meant for industrial and automotive use to have a separate supply for the I/O ports, that can go up to 5V, independent from the core/peripheral voltage.

The main use is to drive (logic-level) MOSFETs directly, interface to 5V buses like SENT, CAN, etc. without having to use level shifters.

Yeah, would be interesting if they integrated it ala STM32MP1[1][2].

PWM outputs are nice too. For power electronics, center aligned complementary pairs with dead time are a must.

I think that's what the PIO state-machines are for — offloading timing-sensitive I/O logic and waveform generation.
