Intel® System Controller Hub US15W for Embedded Computing

  • Overview
  • Technical Documents
  • Where to Buy

The Intel® System Controller Hub (SCH) US15W is a low-power, highly integrated chipset in one small 22x22 mm package that addresses key requirements of small form factor, 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, interactive client (kiosks, point-of-sale terminals), gaming, and industrial control.

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 Audio¹ and hardware video decode acceleration. It supports a 400/533 MHz CMOS front-side bus (FSB), dual independent display, 1 GB max memory down in a single channel with one or two ranks.

Features overview

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.
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 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 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.
  • SMBus Host Controller is compatible with most I2C devices, while LPC 1.1 enables firmware hub, embedded controller, and other legacy devices.
  • Single-channel PATA interface supports two devices (master/slave), and two x1 ports support PCI Express Base Specification Revision 1.0a.
