| Processor |
Intel® Pentium® 4 processor
at 2.4GHz. The Pentium 4 processor supports a 400/533MHz
system bus as well as Intel’s NetBurst™ micro-architecture.
Both features combine to provide optimum system performance
and fast program execution in a PCI/ISA single board computer.
Some of the processor features that enable such performance
enhancements are: • Hyper-Pipelined technology • Streaming
SIMD Extensions 2 (SSE2)• Advanced Dynamic Execution • 512K
Advanced Transfer Cache (L2)• Execution Trace Cache
that stores up to 12K of micro-operations and an 8K Data
Cache (L1) Intel's Hyper-Threading technology makes the Pentium
4, 3.06GHz processor appear as two logical processors. The
operating system and application must be optimized for Hyper-Threading.
This feature delivers faster program execution by enabling
simultaneous instruction processing using the two logical
processors.

| Cache Memory (L2 and L1) |
The Pentium 4 processor supports a 512K integrated
on-die Advanced Transfer Cache (L2). The cache is an 8-way
set associative cache running at full processor core frequency.
It include a 12K level one (L1) Execution Trace Cache and
8K L1 data cache.
|
| Chipset |
he chipset supports a 400/533MHz system bus,
a maximum of two double-sided DIMMs with unbuffered DDR 200/266
(PC1600/PC2100) memory with ECC and a 266MB/s Hub Interface
to the ICH4 I/O Controller.
|
| Ultra 160 SCSI Interface |
The Ultra160 SCSI interface uses an Adaptec
AIC-7892 SCSI controller chip and supports SCSI device data
transfer operations up to 160MB/s. The interface supports
up to 15 SCSI devices, complies with the SPI-3 standard and
is compatible with both single-ended and Low Voltage Differential
(LVD) SCSI I/O. Software drivers are available for most popular
operating systems.
|
| Dual Ethernet Interfaces |
LAN 1 provides a 10/100Base-T Ethernet interface
using Intel’s 82562ET Platform LAN Connect device and
the ICH4 I/O Controller Hub. The 82562/ICH4 combination provides
high-speed data transfers while offloading communication
tasks from the system CPU. LAN 2 supports both 10/100Base-T
and 1Gigabit Ethernet interfaces via Intel’s 82540
controller.
|
| EIDE Ultra ATA/100 Interfaces (Dual) |
Dual high-performance PCI EIDE interfaces
are capable of supporting up to two IDE disk drives each
in a master/slave configuration. The interfaces support Ultra
ATA/100 with synchronous ATA mode transfers up to 100MB per
second.
|
| DDR200/266 Memory |
The DDR200/266 interface is a single-channel
interface coming off the Memory Controller hub and terminating
at two DIMM module sockets. The DIMM sockets can be independently
populated with either PC1600 or PC2100 unbuffered memory
modules with ECC. The memory interface supports auto detection
of memory up to 2GB. Depending on the processor’s system
bus speed and which memory module type is used, the memory
interface bandwidth is either 1600MB/s or 2100MB/s.

|
| BIOS (Flash) |
The OSS-SBC-P4 uses AMIBIOS8. The flash BIOS
resides in the 82802 Firmware Hub (FWH). AMIBIOS8 contains
useful features such as: • CMOS setup for system parameters • Peripheral
management for configuring on-board peripherals • PCI-to-PCI
bridge support and PCI interrupt steering • Support
for flash devices for BIOS upgrading via floppy interface.
Some of the new AMIBIOS8 features supported on the OSS-SBC-P4
include: • Integrated support for USB mass storage devices
such as USB CD-ROM, CD-RW, etc. • Faster POST execution • Improved
BIOS code modularity which streamlines the BIOS customization
process while offering a higher degree of BIOS customization.
|
| Super XGA Interface |
The Intel 69030 video controller has 4MB of
on-chip memory and supports up to 1280 x 1024 pixel resolutions.
Software drivers are available for most popular operating
systems.

| Additional T4I Features |
|
| System Hardware Monitor |
• The Winbond W83783S chip supports hardware
monitoring.The functions monitored are: -Voltage: +3.3V,
+/-12V, +5V and VCORE — Fan speed -Temperature
|
| |
• The OSS-SBC-P4 hardware monitor driver
allows the user to program the monitor limits to provide
a trigger point for the application software. The user’s
application program can monitor these trigger points in order
to send system alert messages or perform corrective actions.
|
| Watchdog Timer |
• The programmable watchdog timer provides
a system reset with a total range of 30ms to 60 seconds.
The programmable increments of the watchdog are 30ms, 10s
and 60s.

*From Backplane via PICMG® Connector
|
| |
** From ATX12V power supply or equivalent
via P4 connector/ The processor’s power requirements
created the need for an additional on-board 4-pin power connector
(P4). This connector requires +12V from an external power
supply that conforms to the ATX12V power certification. This
external power supply should have a minimum wattage rating
of at least 250W. The OSS-SBC-P4 also requires that 3.3V
be applied to the backplane from the power supply.

The high-performance Pentium 4 processor can
consume as much as 70 Watts of power. The OSS-SBC-P4’s
