1 . 6 Pow e r R e qui r e m e n t s
Your system requires a clean, steady power source for reliable performance of the high
frequency CPU on the SPI-6941-LV Industrial CPU card, the quality of the power supply is
even more important. For the best performance make sure your power supply provides a range
of 4.75 volts minimum to 5.25 volts maximum DC power source.
Powe r Co n s u mptio n
For typical configurations, the CPU card is designed to operate with at least a 200 W
power supply. A higher-wattage power supply should be used for heavily-loaded configurations.
The power supply must meet the following requirements:
 Rise time for power supply: 2 ms to 20 ms
The following table lists the power supply’s tolerances for DC voltages:
DC V o l t a g e
Acceptable Tole r a n ce
+ 5 V ± 5 %
+ 5 VSB ( s t andb y ) ± 5 %
+ 12 V ± 5 %

( F C - PG A )
or Pe n t i u m
®
III p roce ss or ( F C - PG A or F C - PG A 2 ) . The CPU core voltage is automatically
adjusted by the voltage regulator on the CPU card, which is connected to the VID pin of the
processor. The processor’s VID pins automatically program the voltage regulator on the CPU
card to the required processor voltage. The host bus speed is automatically selected. The
processor connects to the CPU card through the 370-pins ZIF PPGA socket.
Please change the setting of JP12 in case that you use the CPU other than Tualatine
CPU (PC686-1260). See page 37.
The CPU card supports the processors listed in table below:
Celeron processor (FC-PGA)
Processor Speed Host Bus frequency Cache size
566 MHz to 850MHz 66MHz/100MHz 128KB
Celeron processor (FC-PGA2)
Processor Speed Host Bus frequency Cache size

Pentium III processor (FC-PGA)
Processor Speed Host Bus frequency Cache size
500 MHz to 866MHz 100MHz/133MHz 256KB
Pentium III processor (FC-PGA2)
Processor Speed Host Bus frequency Cache size
1.13GHz to 1.26GHz 133MHz 512KB
The ZIF PPGA socket comes with a lever to secure the processor. Make sure the notch
on the corner of the CPU corresponds with the notch on the inside of the socket.
After you have installed the processor into the socket 370, check if the configuration
setup for the CPU type and speed are correct. The CPU should always have a Heat Sink and a
cooling fan attached to prevent overheating.
N ote : En s u r e that the CP U heat s ink and the CP U top s u r face a r e in total contact to avoid CP U
ove r heating p r oble m that would cau s e you r s y s te m to hang o r be un s table.

The SPI-6941-LV PCIMG PCI/ISA Industrial CPU Card supports three dual inline
memory module (DIMM 168-pin) sockets for a maximum total memory of 1.5GB. Using the
serial presence detect (SPD) data structure, programmed into an E2PROM on the DIMM, the
BIOS can determine the SDRAM’s size and speed. For each slot, minimum memory size is
64MB; maximum memory size is 512MB. Memory size and speed can vary between sockets.
The CPU card supports the following memory features:
• 168-pin DIMMs with gold-plated contacts
• 100 MHz or 133MHz SDRAM
• Non-ECC (64-bit) and ECC (72-bit) memory
• 3.3V memory only
• Unbuffered single or double-sided DIMMs in the following sizes:
S D RA M
S YNC H R O N O U S DRAM (SDRAM) improves memory performance through memory
access that is synchronous with the memory clock. Burst transfer rates at x-1-1-1 timing can be
achieved using SDRAM, while asynchronous memory subsystems are typically limited at x-
2-2-2 transfer rates.
The CPU card supports single or double-sided DIMMs in the following sizes:
D I MM s i z e N on - E CC c on f i gu r a t i on E CC c on f i gu r a t i on
