Released Jan 2011
Merom, the first mobile version of the Core 2, was officially released on July 27, 2006 A native 2 MB L2 version of the Merom core, called Merom-2M, was rolled out in early 2007. A second wave of Merom processors featuring an 800 MT/s FSB and using the new Socket P was launched on May 9, 2007.These chips are part of Santa Rosa platform.
The successor to the Merom core currently used for the Core 2 Duo T5000/T7000 series mobile processors, code-named Penryn, debuted on the 45 nanometer. Many details about Penryn appeared at the April 2007 Intel Developer Forum. The new processors launch exclusively within a 35W thermal envelope. Penryn has also been released for notebooks with companies such as HP beginning to offer the first model, the T9500, from late January 2008. The T9500 offers a 2.5GHz clockspeed, faster than all but the Extreme Edition of the Santa Rosa range, and 6Mb (rather than 4Mb) of Level 2 Cache. However, for now the new range retains the lack of support for DDR3 RAM and an 800Mhz front side bus, due to chipset limitations.

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 27th 2006 onwards.
The Napa platform consists of:
* Processors - Socket M o an Intel Core Solo, Core Duo (code-named Yonah) processor, or o an Intel Core 2 Duo (code-named Merom) processor with a 667 MT/s FSB for Napa Refresh platform. * an Intel Mobile 945 Express series chipset (code-named Calistoga with Intel's GMA 950), including ICH7M southbridge, and o RAM supported for DDR2-533 and DDR2-667 SO-DIMM. * the Intel PRO/Wireless 3945ABG mini-PCIe Wi-Fi adapter (code-named Golan), and o 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.
The code-name Santa Rosa refers to the fourth-generation Centrino platform, which was released on Wednesday 9 May 2007.
* Processors - Socket P o an Intel Core 2 Duo (code-named Merom) second generation processor with 800 MT/s FSB, or o an Intel Core 2 Duo (code-named Penryn) 45nm processor with 800 MT/s FSB scheduled for release in January 2008 for Santa Rosa Refresh platform. * an Intel Mobile 965 Express chipset (code-named Crestline): GM965 with Intel's GMA X3100 graphics technology or PM965 with discrete graphics, and ICH8M southbridge, 800 MT/s front side bus with Dynamic Front Side Bus Switching to save power during low utilization, and o Intel Dynamic Acceleration (IDA), better Windows Vista Aero support. o RAM supported for DDR2-533 and DDR2-667 SO-DIMM. o EFI-compliant firmware, a successor to BIOS. o optional NAND flash-memory caching branded as Intel Turbo Memory (code-named Robson) * the Intel Wireless WiFi Link 4965AGN (a/b/g/draft-n) mini-PCIe Wi-Fi adapter (code-named Kedron). o Wireless-N technology boasts a 5X speed increase, along with a 2X greater coverage area, and supports 2.4 GHz and 5 GHz signal bands, with enough bandwidth for high definition audio and video streams.
The code-name Montevina refers to the fifth-generation Centrino platform, scheduled for release in May 2008
