CPU Mainboard
The CPU Mainboard is packaged as a slide-in module with an integrated heat sink. The circuit board of the
module contains the CPU (Intel® D510 @1.66GHz), the support chipset (Intel® 82801HBM ICH8M), and has 2
SODIMM sockets which supports up to 4 GB of single channel DDR2-667/800 memory. The circuit board also
contains 1 miniCard socket for future expansion. The board is connected to the touch screen, LCD, and other
system devices through the Panel Board Interface connector to Panel I/O board. The video driver is an
Integrated Intel® Graphics Media Accelerator 3150, also located on the CPU Mainboard. The interface to
storage devices is through an Intel 82801HBM controller. The controller supports 1 SATA interface through the
Docking Connector. The controller also provides an interface to a CompactFlash socket on the CPU Mainboard.
An onboard ITE IT8513 Embedded Controller provides 2 UART ports and supports keyboard and mouse ports
(for test only). Dimensions of the CPU Mainboard PWB and connector layout are shown in following two figures.
The Connector Index follows these figures and defines the function of the connectors. The detail of the signal
lines within each connector follows in this section.
