Texas Instruments is pretty chuffed with itself right about now, as it's prepping to demonstrate a swell-sounding new system-on-chip that takes Bluetooth connectivity to the extreme reaches of low energy consumption. About to be shown off in Munich tomorrow, the new CC2540 takes up a measly 6mm-squared of real estate, and is said to be able to operate for more than a year on a single button cell battery. With the reduced physical size and embedded Flash memory, this should be easier to install and update as necessary too. Considering the battery-draining ways of current Bluetooth tech, such claims sound preposterously awesome, but we'll keep our giddy enthusiasm in check until early next year when samples will begin rolling out. For now, you can check out the older video below 'splaining the prospective benefits in more detail.
