Notice
This equipment has been tested and found to comply with the limits for a Class A
digital device pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at the
user’s own expense.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications not expressly approved by Texas
Microsystems could void the product warranty and the user’s
authority to operate the equipment.
This product also meets requirements for compliance with EN55022, Class B ITE.

1.1 P5000HX Features
The P5000HX The Texas Micro P5000HX:
•provides a 100/133/166/200 MHz, 64-bit
Pentium P54C processor,
•contains on-board PCI peripheral devices such
as SCSI and EIDE, and
•features 512 KByte flash memory and a CELP
socket for optional high-speed pipelined burst
SRAM modules (up to 512 KBytes).
Additional features
include... •Support for up to 256 MByte scaleable FPM
DRAM (chip set allows ECC using standard
SIMMs),
•One RS-232 serial port, one programmable
RS-232/422/485 serial port,
•a multi-function enhanced IEEE 1284 parallel
port,
•a floppy disk controller,
•an EIDE hard disk controller , and
•a PCI Bus-to-Fast and Wide SCSI Controller.

1.2 A PCI Discussion
Overview The P5000HX is designed to be used with either an ISA or
a PCI backplane. This section discusses the PCI Local Bus.
The PCI Local Bus The PCI Local Bus is a high-performance, 133 MB/sec,
32-bit bus with multiplexed address and data lines. It is
intended for use as an interconnect mechanism between
highly-integrated peripheral controller components, add-
in boards, and processor/memory systems.
Why the PCI Local
Bus? Graphics-oriented operating systems such as Windows
and OS/2 have created a data bottleneck between the pro-
cessor and its display peripherals in standard PC I/O
architectures. Moving peripheral functions with high-
bandwidth requirements closer to the system’s processor
bus can eliminate this bottleneck.
Substantial performance gains are seen with graphical
user interfaces (GUI’s) and other high-bandwidth func-
tions (i.e., full-motion video, SCSI, LANs, etc.) when a
“local bus” design is used.
The PCI Bridge The processor/cache/memory subsystem in a PCI system is
connected to PCI through a “PCI Bridge.” This bridge pro-
vides a low-latency path through which the processor may
directly access PCI devices mapped anywhere in the mem-
ory or I/O address spaces. It also provides a high-band-
width path, allowing PCI masters direct access to main
memory.
PICMG Texas Microsystems is a founding member of the PICMG
(PCI Industrial Computer Manufacturers Group), founded
to develop standards for PCI-based passive backplane sys-
tems. The P5000HX is fully PICMG-compliant.
