The vast majority of modern MCUs have enough memory protection for Tock. Anything cortex-m0+ or "better" has an MPU. RISC-Vs PMP or ePMP as well. Most 16-bit "legacy" (though still popular) MCUs don't.

Virtually anything with a radio these days (the MSPs were holdouts but mostly those are Cortex-M these days as well)
