Product Description
The CoreModule 920 SBC is a highly integrated, high-performance, Intel  Core™ i7 processor based
system, compliant with PCI Express architecture and the PCI/104-Express form factor. This rugged and high
quality single-board system contains all the component subsystems of an ATX motherboard, plus the
equivalent of several PCI and PCI Express expansion boards.
The Intel Core i7 series CPU integrates a multiple execution core with a Graphics and Memory Controller
Hub (GMCH), providing a high-performance processor, a memory controller for up to 2GB of DDR3 on-
board memory, and a graphics controller that provides VGA, LVDS, and HDMI ports driven by the PCH
(Platform Controller Hub) and one PCIe x16 Graphics (PEG) port driven by the CPU.
Each CoreModule 920 incorporates an Intel BD82QM67 PCH, providing the controller hub for a range of
common user interfaces including six USB 2.0 ports, two serial ports, two SATA 3.0 ports, one SATA 2.0
port dedicated for the SSD, four PCIe x1 lanes, as well as interfaces for GPIO and RTC battery. The
CoreModule 920 provides a Solid State Drive through the SATA2 port for storage up to 8GB, a Hardware
Monitor chip to control temperature and voltage levels, and a Utility interface for Power button, Reset
switch, and Speaker output. The PCH connects to two 10-pin Gigabit Ethernet interfaces through two PCIe
x1 lanes.
The CoreModule 920 can be expanded through the PCIe expansion bus using the PCI-104 and PCIe/104
interfaces for additional system functions. These interfaces offer compact, self-stacking, modular
expandability. The PCI-104 interface implements a PCI bus available on a 120-pin (4 rows of 30 pins) PCI
expansion bus connector. The PCIe/104 interface includes the PCIe signal set plus SMBus and USB 2.0
signals available on top and bottom-side, 156-pin high-speed PCIe connectors. The PCI bus operates at a
clock speed of up to 33MHz, and the PCIe bus operates at a clock speed of up to 100MHz.
The CoreModule 920 is particularly well suited to either embedded or portable applications and meets the
size, power consumption, temperature range, quality, and reliability demands of embedded system
applications. It can be stacked with ADLINK expansion modules or other PCI/104-Express-compliant
expansion modules, or it can be used as a powerful computing engine. The CoreModule 920 requires a
single +5V AT power source.
