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[2]: 1mm x 1mm sounds way too big

1um^2 is roughly an area of a single gate (assuming a reasonably new CMOS process and not too complex gate, flip-flop's are several times larger). But since 1mm^2 = 1e+6 * 1um^2 there is plenty of room for gates.
