The primary difference between these processors and all prior versions, is that ECC memory support has been added, enabling the use of the Atom in mission-critical server environments that demand redundancy and memory failure protection. In December 2012, Intel released Atom for servers, the S1200 series. In April 2008, a MID development kit was announced by Sophia Systems and the first board called CoreExpress-ECO was revealed by a German company LiPPERT Embedded Computers, GmbH. Intel and Lenovo also jointly announced an Atom powered MID called the IdeaPad U8. Several Mini-ITX motherboard samples have also been revealed. The more expensive lower-power Silverthorne parts was to be used in Intel mobile Internet devices (MIDs) whereas Diamondville was to be used in low-cost desktop and notebooks.

Silverthorne would be called the Atom Z5xx series and Diamondville would be called the Atom N2xx series. Īt Spring Intel Developer Forum (IDF) 2008 in Shanghai, Intel officially announced that Silverthorne and Diamondville are based on the same microarchitecture. "Atom" was the name under which Silverthorne would be sold, while the supporting chipset formerly code-named Menlow was called Centrino Atom. However, Intel revealed on Octothat it was developing another new mobile processor, codenamed Diamondville, for OLPC-type devices. Prior to the Silverthorne announcement, outside sources had speculated that Atom would compete with AMD's Geode system-on-a-chip processors, used by the One Laptop per Child (OLPC) project, and other cost and power sensitive applications for x86 processors. Intel Atom is a direct successor of the Intel A100 and A110 low-power microprocessors (code-named Stealey), which were built on a 90 nm process, had 512 kB L2 cache and ran at 600 MHz/800 MHz with 3 W TDP (Thermal Design Power). On SeptemIntel launched a 22 nm successor to Centerton, codenamed Avoton. Centerton adds features previously unavailable in Atom processors, such as Intel VT virtualization technology and support for ECC memory. In December 2012, Intel launched the 64-bit Centerton family of Atom CPUs, designed specifically for use in servers. On December 28, 2011, Intel updated the Atom line with the Cedar processors. On December 21, 2009, Intel announced the Pine Trail platform, including new Atom processor code-named Pineview (Atom N450), with total kit power consumption down 20%.
The first generation of Atom processors are based on the Bonnell microarchitecture.
The line was originally designed in 45 nm complementary metal–oxide–semiconductor ( CMOS) technology and subsequent models, codenamed Cedar, used a 32 nm process. Atom is mainly used in netbooks, nettops, embedded applications ranging from health care to advanced robotics, and mobile Internet devices (MIDs). Intel Atom is the brand name for a line of IA-32 and x86-64 instruction set ultra-low-voltage microprocessors by Intel Corporation designed to reduce electric consumption and power dissipation in comparison with ordinary processors of the Intel Core series.
