It's not a micro, but there are microcontrollers that are comparable in size. An AVR ATtiny20 is available in a 1.5mm x 1.4mm package. That's just about a 2mm^2

- zokier 8y agoAnd not just itty ATtinys, for example MAX32660 is full fat ARM M4F core in 1.6x1.6 mm package. It is the sort of thing you could hide pretty much anywhere. For reference here is a picture of similar package (called wlcsp or variation of thereof): https://img.youtube.com/vi/edERx4x5eY0/maxresdefault.jpg https://img.youtube.com/vi/edERx4x5eY0/maxresdefault.jpg
