Intel Atom is the brand name for a line of ultra-low-voltage IA-32 and x86-64 CPUs (or microprocessors) from Intel, originally designed in 45 nm CMOS with subsequent models, codenamed Cedar, using 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). 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.
