C-32 — D-64 E-128 F-256

IoT sensors, legacy industrial machines, basic Arduino boards, and older gaming consoles (PlayStation 1, Nintendo 64’s 64-bit is actually a mix, but many co-processors were 32-bit).

These numbers correspond to (if we multiply by 8, except here they are already in byte multiples): c-32 d-64 e-128 f-256
