  • Where to Buy

The Intel® System Controller Hub (Intel® SCH) US15W, available in two package sizes, is a low-power, highly integrated chipset that addresses key requirements of thermally constrained and fanless embedded applications.

The Intel SCH US15W is validated with the Intel® Atom processor Z5xx series. This platform has a combined TDP under 5 watts and features embedded lifecycle support, making it ideal for many embedded market segments such as in-vehicle infotainment, medical, retail and transaction solutions (kiosks and point-of-service terminals), gaming, industrial control, and automation.

For design flexibility, the Intel SCH US15W is offered in two package sizes. A small footprint version in a 0.6 mm ball pitch and 1.0 ball pitch, is available for designs without such tight board space restrictions. The larger version also has an industrial temperature SKU option.

Product information

Product highlights

The Intel® System Controller Hub US15W 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 Audio (Intel® HD Audio)¹ and hardware video decode acceleration. It supports a 400/533 MHz CMOS front-side bus (FSB), dual-independent display, 2 GB max in a single channel with one or two ranks.

Features overview

Graphics and display
  • Intel® Graphics Media Accelerator 500 (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
  • Single Channel 24-bit LVDS and SDVO display ports
  • Features include screen tiling, internal true color processing, zero overhead anti-aliasing, programmable shader 3D accelerator, and 32-bit floating-point operations
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 decode and off-loading 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 Supports:
  • Eight USB 2.0 ports (including one USB client port)
  • Three secure digital I/O 1.1 and multimedia card controller 4.0 ports
  • Single-channel PATA
  • Two PCI Express* ports
  • SMBus host controller
  • LPC 1.1 interface
