Abstract
A 12pJ/instruction microcontroller with embedded SPAM designed specifically for use in mm3 wireless sensor nodes is described. It features highly independent subsystems for sensor sampling, transmission, and receiving that maximize the datapath sleep time as well as 100nW integrated oscillators with rapid power-cycling. Designed in 0.25μm technology, the 0.38mm2 core consumes 5.9μW from a 1V supply when running at 500kHz.
