Intel® Pentium® 4 processor
at 2.8GHz
|
| Chipset |
Intel's 875P chipset provides support for
a faster system bus, DDR200/266 memory and dual USB 2.0 compatible
interfaces.
|
| System Bus |
The Intel 875P chipset supports a system bus
speed of 400/533MHz.
|
| Bus Speed |
ISA 16-bit/8MHz
|
| |
PCI 32-bit/33MHz
|
| |
System/FSB 400/533MHz
|
| BIOS (Flash) |
AMIBIOS8 with built-in advanced CMOS setup
for system parameters, peripheral management for configuring
on-board peripherals, PCI-to-PCI bridge support and PCI interrupt
steering. Supports flash devices for BIOS upgrading via floppy
interface. Also provides integrated support for USB mass
storage devices such as USB CD-ROM, CD-RW, etc. Custom BIOSs
are available upon request.
|
| Cache Memory (L2 AND L1) |
The P4 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 includes
a 12K level one (L1) Execution Trace Cache and 8K L1 data
cache.
|
| DDR200/266 Memory |
Double Data Rate (DDR) memory improves memory
data speeds demanded in data-intensive applications. 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. The
memory interface supports auto detection of memory up to
2GB. The bandwidth of the DDR200/266 memory interface is
1600MB/s or 2100MB/s.
|
| ULTRA160 SCSI Interface |
The Ultra160 SCSI interface uses an Adaptec
SCSI controller that supports SCSI device data transfer operations
up to 160MB/s. The interface 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.
|
| PCI Bus Interface |
The PCI bus interface supports a 32-bit PCI
backplane interface running at a 33MHz bus speed.
|
| ISA Bus |
The OSS-SBC-T4I provides a 16-bit ISA bus
interface to the backplane for legacy ISA slots.
|
| System Hardware Monitor |
The Winbond W83783S chip supports hardware
monitoring. The functions monitored are voltage, fan speed
and temperature. The OSS-SBC-T4I hardware monitor driver
allows the user to program the monitor limits to provide
a trigger point for the application software. This allows
the application program to monitor these trigger points in
order to send system alert messages or perform corrective
action.
|
| Floppy Dirve Interface |
Supports up to two floppy disk drives in combinations
of 360K to 2.88MB.
|
| Super XGA Video Interface |
The Intel 69030 video interface has 4MB of
on-chip memory and supports pixel resolutions up to 1280
x 1024. Software drivers are available for most popular operating
systems.
|
| Serial Interface |
The Super I/O controller supports two full-function
serial ports with independently programmable baud rates.
The controller has two high-speed, NS16C550 compatible UARTs
with Send/Receive 16-byte FIFOs. The IRQ for each serial
port has BIOS selectable addressing.
|
| Dual Ethernat Interfaces — 10/100BASE-T AND
10/100/1000BASE-T |
There are dual Ethernet LAN ports on the OSS-SBC-T4I.
LAN Port 1 functions as a traditional 10/100Base-T port,
while LAN Port 2 offers Gigabit (1Gb/s) connectivity in addition
to the traditional 10/100Base-T interface. RJ-45 connectors
located on the I/O bracket provide the mechanical interface
to the Ethernet networks.
|
| EIDE Ultra ATA/100 Interfaces (DualL) |
Dual high-performance PCI Bus Master EIDE
interfaces are capable of supporting up to two IDE disk drives
each in a master/slave configuration. The interface supports
Ultra ATA/100 with synchronous ATA mode transfers up to 100MB
per second.
|
| 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.
|
| Enhanced Bi-Directional Parallel Interface |
The parallel port interface is compatible
with IBM PC/XT®, PC/AT®, PS/2™, Enhanced Parallel
Port (EPP1.7, EPP1.9) and Extended Capabilities Port (ECP)
modes of operation. Both the EPP and ECP modes are IEEE 1284
compliant. The parallel port has BIOS selectable addressing.
|
| Keyboard and PS/2 Mouse Interfaces |
The mini DIN connector located on the I/O
bracket provides an external interface for a PS/2 mouse and
keyboard. A "Y" adapter plugged into the mini DIN
connector allows the PS/2 mouse and keyboard to share the
same port. Internal PS/2 mouse and keyboard headers are also
available. A self-resetting fuse protects the +5V line of
the keyboard and the mouse.

| Power Requirements |
Typical Values
|
| |
Pentium 4:
|
| |
CPU +5V* +12V# +3.3V*
|
| |
2.8GHz/533MHz 4.05A 4.68A 2.75A
|
| |
2.4GHz/533MHz 3.96A 3.91A 2.68A
|
| |
2.0GHz/400MHz 4.00A 3.38A 2.66A
|
| |
The Pentium 4 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 specification. This
external power supply should have a minimum wattage rating
of at least 250W. The OSS-SBC-T4I also requires that 3.3V
be applied to the backplane from the power supply.
|
| Power Fail Detection |
The OSS-SBC-T4I continuously monitors the
incoming +5V and +3.3V power lines from the system backplane.
If the 5V line drops below 4.75 volts or the +3.3V line drops
below 2.97 volts, the OSS-SBC-T4I issues a hardware-reset
command. This feature helps maintain control and allows the
system to automatically restart. A two-pin header is available
for applications that require an external reset switch. On-board
power lines are also monitored in a similar fashion.
