If you mean this one, no - it's a pure 5V PCI card. (I have no idea why
the text says SCSI, it's definitely an ISDN card!):
isic0@pci0:17:0: class=0x028000 card=0x10001048 chip=0x10001048
rev=0x01 hdr=0x00
vendor = 'ELSA GmbH'
device = 'QuickStep 1000 PCI to SCSI Bridge'
class = network
In general, if you really need a card that uses only 3V3 power, I think
you are out of luck - all the cards I have looked at need 5V for driving
the line.
However, you actually meant that you need a card for a "3V3 PCI slot",
that's a different matter altogether (a "3V3 PCI slot" uses 3V3 signalling
levels, but still has all the normal power supplies).
I have found two PCI cards that will go in a 3V PCI slot (both
dual-voltage cards, since the majority of PCs have 5V slots and so there's
no market for 3V-only cards).
One is the AVM Fritz!Card PCI version 2 (version 1 is 5V-only), now
supported by the ifpi2 driver.
The other is the ASUS ISDNLink 128K - again, this comes in various
different versions, and only the more recent version (P-IN-ST-D2) is
dual-voltage. This has the Cologne Chip Design chipset, so might
theoretically be supported by the ihfc driver, but last time I checked
there was no PCI attach code in the ihfc driver, so it is not currently
supported.
