FUNCTIONAL DESCRIPTION
The cPCI bus is driven by a 64-bit PCI to PCI Bridge and supports
up to seven bus master slots. The primary PCI bus is applied to the local
on-board PCI device and available from on-board PMC connectors. The TRL
6221 fully supports one or two Intel Specification for Pentium III class
processors providing the latest computing power for the user. Auto
configuration of split voltage devices is supported, allowing jumper-less
use of many versions of Pentium III class CPUs with performance to 1GHz.
The 440BX/GX PCI chipset from Intel is designed to maximize throughput on
the PCI bus. It is capable of burst mode transfers to 110 Mbytes per second
between PCI and main memory. It also supports PC100 SDRAM and error
correction (ECC) memory providing the highest data protection. Jumper-less
setups of interrupt requests and configuration options are configurable
through the BIOS setup screen. User-defined temperature and time settings
for adjustable CPU clock rate and critical system shutdown limits are
designed for maximum thermal protection and the highest equipment MTBF
performance.
HOT SWAP
TRL
6221 allows hot swap compliant add-on boards on the cPCI bus to be removed
or inserted with power on. Individual clocks for each slot on back plane
must be provided. Add-on boards access to the back plane ENUM# signals are
required to be in compliance with the PICMG 2.1 Hot Swap Specification. The
TRL6221 is not intended to inserted or removed in a powered system.
THERMAL MANAGEMENT
With
external forced air-cooling and with adequate ventilation, cooling is
achieved with an integrated heat sink. Built in with National LM79
environment sensors, the TRL 6221 is rated for 0° to 55° C operation up to
1GMHz processor.
DRAM PERFORMANCE
Total capacity up to 2Gbytes of
PC100MHz SDRAM on four DIMM socket is used for high performance. Optional
Error Correcting (ECC) DRAM is available for improved reliability and data
integrity.
FLASH MEMORY
TRL 6221 comes with up to 4Mbits
of on board flash memory for system BIOS. Optional user defined application
flash memory can be upgraded from 16M up to 576M Bytes on a DIP socket.
These optional flash memories can be use as a solid-state disk or to store
a bootable operating system image.
CACHE MEMORY
The processor contains internal
Level one (L1) cache memory. Level two (L2) cache is provided on-board the
Intel CPU module.
ON BOARD PERIPHERALS
The TRL6221 contains many PC
standard on-board peripherals, making it a very powerful stand alone single
board computer as well as a sophisticated main cPCI processor. In addition
to the standard keyboard, timers, real-time clock, two serial (16550) ports
and IEEE-1284 bi-direction parallel ports, it also contains two Enhanced
IDE (EIDE) controllers, a mouse port, a floppy controller, two Universal
Serial Bus (USB) ports and a dual 10/100MB Ethernet ports.
AGP DISPLAY PORT
The display port provides an
on-board highly integrated AGP video processor with 2MB or optional 4MB
memory supporting up to 1280x1024 resolution.
WATCHDOG TIMER
The watchdog timer can be set by
the user to monitor system operation. Failure of the data to strobe the
watchdog timer within a fixed time period will provide auto power-on reset
for the system.
ENHANCED IDE INTERFACE
TRL 6221 provides support for two
integrated PCI-based Enhanced IDE (EIDE) controllers. The primary EIDE
provides the option for two IDE devices integrated on the Peripheral Device
Carrier board. It is mounted on the TRL6221 to become a three-slot
configuration. Both the primary and secondary EIDE channels are available
through the rear-panel I/O J3 connector.
FLOPPY INTERFACE
An on-board floppy disk controller
provides the option for an integrated floppy disk drive. The floppy disk
drive signals are routed to the rear-panel I/O J3 connector for off-board
support.
KEYBOARD AND MOUSE
The TRL6221 supports a PS/2 style
keyboard and mouse connector at the front panel as well as through the
rear-panel I/O J3 connector.
SWITCHES AND INDICATORS
System power-on reset and Non
Maskable Interrupt (NMI) reset switches are accessible from the front
panel. LED’s are provided on the front-panel for EIDE activities, Ethernet
negotiation and speed status, system power status, CPU activities and
optional user defined functions.
BACK PANEL I/O CARD
The TRL 6221 brings most I/O
signals out of the rear of the board on J3 and J5. These signals can be
connected via a rear-panel 6U transition board TRL 1215.
PMC EXPANSION SLOT
The optional built-in PMC bus makes
the TRL6221 configurable for a wide range of system requirements. One user
defined 55 pins connection is available for interface with back panel I/O
on J5. The two optional on-board PMC slots are available on the SBC solder
side to be integrated as a three-slot configuration.
PERIPHERAL ADAPTER
The optional Peripheral Adapter
mounted on top the SBC to be integrated as a three-slot configuration. The
Adapter can accommodate two EIDE devices such as LS120 floppy drive, CDROM
and hard drives or flash IDE drives.
SOFTWARE SUPPORT
The TRL6221 comes standard with AMI BIOS. Options are available for OS boot
files loaded to on-board flash. The BIOS is user configurable to boot up
from local flash memory, a fixed or floppy drive or over a network. The flexibility
of the BIOS allows the TRL6221 to operate in many configurations to support
all popular operating systems such as all MS Windows OS, QNX, VxWorks,
Linux and Sun Solaris x86.
