Texas Instruments will showcase an ultra low-power coin cell demo using the upcoming Bluetooth low energy open standard on Tuesday at a Bluetooth conference in Munich. The device will use TI's future CC2540 single-mode system-on-chip, which TI says will consume so little power that it will allow wireless to run on devices for very long periods of time. Among other examples, it would allow for a small button cell battery to power such a device without recharging for more than a year.
