Apple snaps up low-power chipset firm Passif Semiconductor

Apple (NASDAQ:AAPL) confirmed that it bought low-power silicon provider Passif Semiconductor for an undisclosed sum. The deal, which was first reported by former Wall Street Journal reporter Jessica Lessin, is being closely watched because of Apple's indications that it could be getting into the field of wearable computing. Passif's chips could be used for those kinds of devices, and according to Lessin, the company's silicon includes a radio that works with a low-energy version of Bluetooth called Bluetooth LE, which can be used for health-monitoring and fitness devices that need extra-long battery life. Apple already supports Bluetooth LE in the iPhone 4S and iPhone 5, according to GigaOM. As AllThingsD notes, Apple's purchase of Passif follows those of crowdsourced location data company Locationary and online transit-navigation app maker HopStop. Article
