Centrino-Napa platform (2006)

The code-name Napa designates the third-generation Centrino platform, introduced in January 2006 at the Winter Consumer Electronics Show. The platform initially supported Intel Core Duo processors but the newer Core 2 Duo processors were launched and supported in this platform from July 27, 2006 onwards.
The Napa platform consists of:
Processors - Socket M / Micro-FCBGA
an Intel Core Solo, Core Duo (code-named Yonah) processor, or
an Intel Core 2 Duo (code-named Merom) processor with a 667 MT/s FSB for Napa Refresh platform, or
an Intel Core 2 Solo (code-named Merom) processor with 553 MT/s FSB for Napa Refresh platform (Sept 2007), and
an Intel Mobile 945 Express series chipset (code-named Calistoga with Intel's GMA 950), including ICH7M southbridge, and
RAM supported for DDR2-533 and DDR2-667 SO-DIMM.
the Intel PRO/Wireless 3945ABG mini-PCIe Wi-Fi adapter (code-named Golan), and
Some newer models (as of 1st quarter 2007) of the Napa Refresh platform contain the newer 4965AGN (a/b/g/draft-n) wireless cards.
Intel uses Centrino Duo branding for laptops with dual-core ("Core Duo") and ("Core 2 Duo") processors and retains the Centrino name for laptops with single core ("Core Solo") processors. Some of the initial Core Duo laptops, are still labeled as Intel Centrino rather than Centrino Duo.
