According to Jessica Lessin, Apple has acquired chip development firm Passif. The company’s chip technologies are focused on utilizing low-power and work with low-energy Bluetooth technologies.

As Apple moves towards smaller devices, the talent and resources of Passif will be critical. Apple reportedly tried to buy the firm a few years earlier, but was only able to strike a deal within recent months. We previously reported that Apple has been poaching several employees from other chip makers to work on the upcoming iWatch.

Apple confirmed the Passif acquisition. In recent weeks, Apple has also acquired mapping firms Locationary and HopStop.
