When Nokia debuts its new smartphones running on Microsoft's Windows Phone operating system, at least some of the devices will be powered by silicon from ST-Ericsson, said Carlo Bozotti, the Chief Executive of European semiconductor maker STMicroelectronics.
Nokia will be using ST-Ericsson chipset U8500, a dual-core SoC that can also be found in the Samsung Infuse 4G and the T-Mobile Sidekick 4G, in its Windows Phone 8 devices.
Even after the Microsoft deal ST-Ericsson continues to have "very close relations" with Nokia, said Bozotti, and will be "an important supplier" for Nokia's Windows Phone 8 phones. (The first/current wave of Windows Phone devices is called Windows Phone 7 but the next generation of Windows Phones will be known as Windows Phone 8.)
The first ST-Ericsson chipset that will appear in a Nokia Windows Phone is the U8500, a sophisticated dual-core system-on-a-chip that can also be found in the new Samsung Infuse 4G smartphone on AT&T and the T-Mobile Sidekick 4G.
Later Nokia Windows Phones -- the company is planning to release 12 Windows Phone devices over the course of 2012 -- will run on future versions of the U8500, said Bozotti.
