RP2040 has an MPU as well, just FYI
Also, good luck GETTING an STM32H7/F7. I've had an order outstanding for ~13 months, expecting parts in 3 more moths. All this while i was able to buy RPO2040 trivially. There is something to be said for actually being able to GET the chip, even if it is not the perfect tool for your job.

- dmitrygr 4y ago100% wrong C-m0+ has an optional MPU: https://developer.arm.com/documentation/dui0662/b/Cortex-M0--Peripherals/Memory-Protection-Unit https://developer.arm.com/documentation/dui0662/b/Cortex-M0-... RP2040 has it: https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.p.... (page 76)
