Samsung is set to build the processor for the S1 chips in the Apple Watch, which should ship in March, say sources for
DigiTimes -- a Taiwanese trade paper with a mixed track record on predictions. The company has reportedly received orders for 3,000 to 4,000 12-inch wafers per month, manufactured using its 28nm process (how many S1 chips are included on a wafer has not been revealed). Another firm, Advanced Semiconductor Engineering, is
slated to provide system-in-package modules.
The S1 may be Apple's most compact chip design yet. Unlike the hardware in iPhones and iPads, the S1 is designed to be a complete system-on-chip, merging every necessary component. While
DigiTimes is not always a reliable source of information, the March launch window mentioned in the claim is
consistent with other recent reports.
