Intel® Atom™ Processor

The Intel® Atom™ processor Z5xx series delivers the benefits of Intel® architecture for small form factor, thermally constrained and fanless embedded applications.

Implemented in 45nm technology, these power-optimized processors provide robust performance per-watt in an ultra-small 13x14mm package.

 

These single-core processors are validated with the Intel® System Controller Hub US15W, which integrates a graphics memory controller hub, and I/O controller hub into one small 22x22mm package that addresses key requirements of small form factor, thermally constrained and fanless embedded applications (it has a TDP - Thermal Design Power - of 2.3Watts)

It combines the Intel® Graphics Media Accelerator 500 (Intel® GMA 500), memory controller, and I/O controller in a single-chip solution, while featuring advanced 3D graphics and extensive I/O capabilities such as USB 2.0, SDIO and PCI Express.

Additionally, it supports Intel® High Definition Audio1 and hardware video decode acceleration.

It supports a 400/533MHz CMOS front-side bus (FSB), dual independent display, and 1GB max memory down in a single channel with one or two ranks.

 

This new, two-chip platform provides more than 80% reduction in total footprint over the previous-generation three-chip solution, based on the Intel® Celeron® M processor Ultra Low Voltage with Mobile Intel® 945GME Express chipset, and has a combined TDP under 5Watts

The platform is also supported by the Intel® Embedded Graphics Drivers and video BIOS, developed specifically for embedded products and applications.

Processor Features

  • Available in two options :
    • Intel® Atom™ processor Z530 at 1.6GHz core speed with 533MHz CMOS front-side bus (FSB), 2.2Watts thermal design power (TDP) and support for Hyper-Threading Technology (HT Technology)
    • Intel® Atom™ processor Z510 at 1.1GHz core speed with 400MHz CMOS FSB, and 2.0Watts TDP
  • Intel’s hafnium-based 45nm Hi-k silicon process technology reduces power consumption, increases switching speed, and significantly increases transistor density over previous 65nm technology.
  • Multiple micro-ops per instruction are combined into a single micro-op and executed in a single cycle, resulting in improved performance and power savings.
  • In-order execution core consumes less power than out-of-order execution.
  • HT Technology (1.6GHz SKU only) provides high performance per-watt efficiency in an in-order pipeline. HT Technology provides increased system responsiveness in multi-tasking environments. One execution core is seen as two logical processors, and parallel threads are executed on a single core with shared resources.
  • New C6 state removes power from processor core and caches, resulting in less leakage than C4 state.
  • Split VTT rail removes power from ~90% of the I/O, reducing C6 state leakage and achieving a significantly lower idle power.
  • Dynamic L2 cache sizing reduces leakage due to transistor sleep mode.
  • SSE3 instruction set enables software to accelerate data processing in specific areas, such as complex arithmetic and video decoding.
  • Enhanced Intel SpeedStep® Technology reduces average system power consumption.
  • Execute Disable Bit2 prevents certain classes of malicious “buffer overflow” attacks.
  • Along with a strong ecosystem of hardware and software vendors, including members of the Intel® Embedded and Communications Alliance (intel.com/go/eca), Intel helps cost-effectively meet development challenges and speed time-to-market.
  • Embedded lifecycle support protects system investment by enabling extended product availability for embedded customers.

Controller Hub Features

  • Graphics and Display
    Intel GMA 500 is a flexible, programmable architecture that supports shader-based technology, 2D, 3D and advanced 3D graphics, high-definition video decode, and image processing. Features include screen tiling, internal true color processing, zero overhead anti-aliasing, programmable shader 3D accelerator, and 32-bit floating-point operations
    Dual display pipes with rotation support, along with low-voltage differential signaling (LVDS) and serial DVO (SDVO) display ports, permit simultaneous independent operation of one display or two. SDVO adapters provide interfaces to a variety of external display technologies such as DVI, TV-out, and analog CRT
    The LVDS interface allows the Intel GMA 500 to communicate directly to a flat-panel display. It supports 18-bit or 24-bit color and EDID and EDID-less displays with a maximum pixel clock of 112 MHz. SDVO may be used for any external display device (HDM/DVI, analog TV, VGA/CR and LVDS). It includes EDID and EDID-less support, and a 160 MHz pixel clock.
  • Video
    Hardware video decode acceleration relieves the decode burden from the processor and reduces power consumption of the system.
  • Full hardware acceleration of H.264, MPEG2, VC1, and WMV9 is supported, eliminating the need for software CODEC and offloading the processor.
  • Audio
    Intel High Definition Audio supports up to four audio streams (up to 16 channels each), 32-bit sample depth, and sample rates to 192 KHz.
  • Interfaces
    The Intel SCH US15W supports eight USB 2.0 ports, and three Secure Digital I/O 1.1 (1-bit or 4-bit) and Multimedia Card Controller 4.0 (1-bit, 4-bit or 8-bit) ports. The SMBus Host Controller is compatible with most I2C devices, while LPC 1.1 enables firmware hub, embedded controller and other legacy devices. A single-channel PATA interface supports two devices (master/slave), and two x1 ports support PCI Express Base Specification Revision 1.0a.
    Advanced Configuration and Power Interface (ACPI) management exposes platform power management features and details to the operating system, allowing application control of system sleep states, device power states, CPU power states, CPU performance states, and CPU throttling states.
