Intel Atom was the brand name for a line of ultra-low-voltage IA-32 and x86-64 microprocessors by Intel Corporation. Atom was mainly used in netbooks, nettops, embedded applications ranging from health care to advanced robotics, and mobile Internet devices (MIDs). The line was originally designed in 45 nm complementary metal–oxide–semiconductor (CMOS) technology and subsequent models, codenamed Cedar, used a 32 nm process.
The first generation of Atom processors are based on the Bonnell microarchitecture. On 21 December 2009, Intel announced the Pine Trail platform, including new Atom processor code-named Pineview (Atom N450), with total kit power consumption down 20%. On 28 December 2011, Intel updated the Atom line with the Cedar processors.
In December 2012, Intel launched the 64-bit Centerton family of Atom CPUs, designed specifically for use in servers.Centerton adds features previously unavailable in Atom processors, such as Intel VT virtualization technology and support for ECC memory. On 4 September 2013 Intel launched a 22 nm successor to Centerton, codenamed Avoton.
In 2012, Intel announced a new system on chip (SoC) platform designed for smartphones and tablets which would use the Atom line of CPUs. It was a continuation of the partnership announced by Intel and Google on 13 September 2011 to provide support for the Android operating system on Intel x86 processors. This range competed with existing SoCs developed for the smartphone and tablet market from companies like Texas Instruments, Nvidia, Qualcomm and Samsung.
