1.2 NuPRO-851 Features
Intel LGA-775 Pentium 4 Processor
The NuPRO-851 is a Full-Sized Single Board Computer (SBC) that
supports a single LGA-775 (775 Land Grid Array) Intel® Pentium®
4 processor.
The Pentium 4 processor runs at a core speed of up to 3.8GHz. The
Intel 915GV chipset keeps the FSB operation at 533/800MHz
(auto-selected).
The design for using Pentium 4 processor required an upgraded
Voltage Regulator Module circuit implementation (VRM 10.1) to
handle tighter voltage tolerances.
Intel® 915GV Graphics & Memory Controller Hub (GMCH)
The central hub for all data passing through core system elements
is through the Intel 915GV Graphics & Memory Controller Hub. To
balance the performance offered by the processor and memory
interfaces, the GMCH allows several high-bandwidth I/O configu-
ration options. This chipset delivers balanced, high-throughput sys-
tem performance for dual processor server platforms.
Intel® 82801FB I/O Controller Hub (ICH6)
Connection to the MCH is done through a point-to-point Hub Inter-
face. The ICH6 provides legacy I/O interfaces through integrated
features including a one-channel Ultra ATA100 bus master IDE con-
troller, four-channel Serial ATA150 and an USB controller for two
USB ports. The ICH6 also offers an integrated System Manage-
ability Bus 2.0 (SMBus 2.0) controller, as well as a PCI 2.2-compliant
interface.
Watchdog Timer
The watchdog timer optionally monitors system operations. It can
be programmed for different timeout periods (from 1 to 255 seconds
or 1 to 255 minutes). The watchdog is capable generating a Reset
signal. Failure to strobe the watchdog timer within the programmed
time period may result in a reset request. A register bit can be
enabled to indicate if the watchdog timer caused the reset event.
This watchdog timer register is cleared on power-up, enabling sys-
