@karotte's field guide to embedded CPU cores:
- does it have a USB connection? 8051
- does it handle USB power delivery? Cortex-M0
- does it process IP packets? MIPS
- is it in some sort of video ASIC? 80186
Yeah, seriously, what's up with the 80186? So far, I've encountered them in
- DP to HDMI converters (MCDP2900A)
- DVD Player SoCs (ZR36966)
- Monitor SoCs (STDP9310)
