Update: Rather than being the next-generation M7 chip, the ‘Phosphorus’ chip shown in the schematics is likely the barometer/air pressure sensor 9to5Mac reported in June. A MacRumors forum member noted the likeliness. Original story below:
Following on from their previous reports, GeekBar is today highlighting a new set of schematics for a chip codenamed ‘Phosphorus’. The site claims the chip will serve similar roles to the M7 in the current iPhone 5s, but with additional functionality. It is very unlikely that Phosphorus will be used in official Apple marketing as it seems to be an internal codename for the chip.
