If you love superlatives, you'll love ARM's new Cortex-M0. Hailed as the smallest, lowest power and most energy-efficient ARM processor available, this chip reportedly enables MCU developers to "achieve 32-bit performance at an 8-bit price point." The company asserts that this processor can consume as little as 85 microwatts/MHz (0.085 milliwatts) in an area of under 12K gates when using the ARM 180ULL cell library, and while that's probably over most of your heads, let's just say that this thing is ripe for use in medical devices, e-metering, lighting, smart control, gaming accessories and the like. Those looking to get this into their next widget should be thrilled to know that it's available today for licensing, though you'll have to phone up someone in the know to talk dollars and cents.
