Hardware, Embedded Systems The Cortex -M0+ architecture is designed to provide chip-makers with the means to build microcontrollers that require "ultra low power" but are capable of 32-bit processing. Arm says it went back to the drawing board to create the new processor cores which measure 1mm by 1mm in size. It says the microcontrollers should draw around a third less energy than their predecessors, which only offered 8 and 16-bit capabilities.

RE: 1mm x 1mm sounds way too big

I expect on a modern process it's questionable if it'll even be visible to the naked eye.

Even if it's so small, so you can't see it, core must be connected to external pins somehow.
