Atom is an family of ultra-low-voltage 32 and 64-bit microprocessors and system on chips designed by Intel since 2008.

Models

Bonnell

Main article: Bonnel Microarchitecture

Bonnell was the first microarchitecture designed specifically for the ultra-low power microprocessor market. Introduced in 2008, it featured fully x86-compatible cores with a TDP of only 500 mW to 2 W, less than any other x86 processor available that the time. Bonnell's low-power came from its simplicity, being an in-order dual-issue piplined CPU. All Bonnell-based processors were manufactured on Intel's 45 nm process.

Silverthorne (MIDs, 1st Gen)

See also: Silverthorne Core

The first series of Bonnell processors were introduced during the 2008 Intel Developer Forum (IDF) in Shanghai, China. Those 32-bit processors were based on the the Silverthorne core which were designed for the Mobile Internet Devices (MID) market. Silverthorne processors have 56 KiB of L1$ and 512 KiB of L2. Silverthorne has support for the traditional AGTL+-based FSB as well as a new low power CMOS FSB specifically introduced to reduce power.

Silverthorne chips consist of 47 million transistors on a 24.2 mm² die. All processors are a single core. Additionally all models support every x86 extension up to SSSE3 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3). The original series of chips that were introduced in 2008 featured a tiny FCBGA-437 package measuring just 13 mm x 14 mm. Intel introduced an set of new models in a much bigger 22x22 mm² FCBGA-441 package. Models ending in P use those large packages. A couple of models (those ending with 'T') also support industrial temperature ranges.

Silverthorne chips have an incredibly simple design featuring only the CPU itself on-die. The southbridge and northbridge are integrated on a secondary Poulsbo chipset which features the memory controller, an integrated graphics, and the various I/O ports.

Lincroft (MIDs, 2nd Gen)

See also: Lincroft Core

Lincroft is the second generation Bonnell-based models, a successor to Silverthorne. Lincroft is drastically different to Silverthorne. It's a complete system on a chip solution, incorporating most of the functionality of the chipset on-die, including the memory controller, display controller, and integrated graphics. Lincroft, along with the Moorestown, models were introduced on May 4, 2010.

Lincroft SoCs where also fabricated on a 45 nm process but incorporate a large part of the southbridge. For those reasons the die is considerably larger, 65.25 mm² incorporating 140,000,000 transistors. As with Silverthorne, all models support every x86 extension up to SSSE3 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3). Lincroft integrates the same Imagination Technologies PowerVR SGX 535 IGP as Silverthorne but operating at double the frequency. Lincroft chips are packaged in an FCBGA-518.

In mid-2011 Intel introduce a number of new chips, as part of the Oak Trail platform, utilizing the SM35 Express chipset.

Diamondville (Nettops)

See also: Diamondville Core

Diamondville-based processors were introduced in mid-2008. Those single-core chips were designed for more complex devices such as light-weight notebooks and various nettops. One dual-core model was also introduced which featured two identical Diamondville in a single package. Diamondville processors have 56 KiB of L1$ and 512 KiB of L2 (twice as much for the dual-core variant).

Diamondville chips consist of 47 million transistors on a 25.96 mm² die. All processors are a single core (except for the 330 which features two 230 dies). Additionally all models support every x86 extension up to SSSE3 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3). These chips utilize the bigger 22x22 mm² FCBGA-441 package.

As with the Silverthorne chips, Diamondville models only incorporate the CPU therefore they must make use of the Calistoga chipset for the memory controller, integrated graphics, and I/O functionality.
