Many chips in Medfield
However, the Medfield platform is not a single chip. It requires a separate power management IC that not only performs power management control but has audio functionality and USB controller on one chip, according to Bell. It is possible that another company may provide this chip.
The wireless modem is also a separate IC; originally the IFX6260 HSPA+ modem IC, from Infineon Technologies AG. That IC became an Intel part when the company acquired the wireless business unit of Infineon at the beginning of 2011 and has been relabeled by Intel variously the IMC6260 or the XMM 6260.
A third-chip within the Medfield platform is a combination connectivity chip from Texas Instruments that provides Wi-Fi, Bluetooth and FM radio and it appears that GPS support comes from CSR plc.
Intel has produced a reference design of smartphone to show off its Medfield platform, which looks a bit like an iPhone. The unit has been flashed around before by various Intel executives when keynoting.

Intel said the design offers 15-days of standby if the smartphone is doing nothing or 7 hours of voice calls or Internet browsing or 8 hours of watching 720p video. The design is capable of 1080p, 30fps video encoding and 1080p, 60fps video playback and supports a 1024 x 768 internal display and a 1920 x 1080 external display.
Medfield is not expected to last too long in the market as Intel has plans to introduce an SoCs based on a CPU called Silvermont in 22-nm CMOS in 2013 and to replace that with an SoC based on a CPU called Airmont in 14-nm CMOS in 2014.
Intel executives declined to say whether there were plans to introduce a
dual-core of the Medfield platform in 32-nm. "Our single-core chip is
competitive with dual-core products from our rivals," said Bell.
Intel's executives declined to talk about the price of the chip in volume except to say that it would be "competitive." Analysts from Nomura Equity Research predicted that Medfield would be introduced at a price of $17 or $18.
