If you're looking for an exceedingly tiny ARM-based microcontroller, Freescale says it's just cooked up the world's smallest. Dubbed the Kinetis KL02, the piece of kit is 25 precent smaller than the previous record-holder and measures up at a 1.9 x 2.00 x 0.56 millimeters. Having trouble visualizing exactly how small that is? Just take a gander at the photo above. A 48 MHz ARM Cortex-M0+ processor has made it onto the wafer-level chip-scale package and it'
