1. Overview

Intel's smallest and lowest power

processor 1.6 GHz (TDP 2.5 W)

The Intel Atom processor enables theindustry to create pocket-sized and low

power Mobile Internet Devices (MIDs), and

Internet-focused notebooks (netbooks)

and desktops (nettops).

This single-core processor is validated with the MobileIntel 945GSE Express chipset, consisting of the Intel82945GSE Graphics Memory Controller Hub and IntelI/O Controller Hub 7-M.

The chipset features power-efficient graphics with anintegrated 32-bit 3D graphics engine based on IntelGraphics Media Accelerator 950 architecture with SDVO,LVDS, CRT, and TV-Out display ports.

It provides rich I/O capabilities and flexibility via high-bandwidth interfaces such as PCI Express,* PCI, Serial

ATA, and Hi-Speed USB 2.0 connectivity. It alsoincludes a single channel for 400/533 MHz DDR2system memory (SODIMM or memory down), and IntelHigh Definition Audio1 interface.

Hyper-Threading Technology3 (two threads)provides high

performance-per-watt efficiency in an in-orderpipeline

and increased system responsiveness in multi-tasking

environments. One execution core is seen astwo logical

processors, and parallel threads are executedon a single

core with shared resources

Enhanced Intel SpeedStep Technology reduces system powerconsumption

Enhanced low-power sleep states (C1E, C2E, C4E) are optimized for powerby forcibly reducing the performance state of the processor when it enters apackage low-power state

Dynamic L2 cache sizing reduces leakage due to transistor sleep mode

Intel Streaming SIMD Extensions (SSE) 2 and Intel SSE3 enablesoftware to accelerate data processing in specific areas, such as complexarithmetic and video decoding

FSB lane reversal enables flexible routing

Execute Disable Bit prevents certain classes of malicious buffer overflowattacks

Along with a strong ecosystem of hardware and software vendors, includingmembers of the Intel Embedded and Communications Alliance(intel.com/go/eca),

Embedded lifecycle support protects system investment by enablingextended product availability for embedded
