Hello,

I am looking for a PCMCIA interface to be included for the processor
which does not have one. To include that, I am looking for some FPGA
solution to take up that role.
Can I directly connect FPGA output to PCMCIA connector or any
transceivers are required in between. Is level translator required in
between?


Any applications notes corrresponding to it?

Thanks and regards
Praveen

PCMCIA is 5V nominal, Cardbus is 3.3V.
Depending on the processor, little more than some glue logic might be needed.

Does your processor have a PCI bus? If so, use a PCI-to-Cardbus
interface chip from TI (or other vendors). The chips also support
the 16-bit PC Card mode (PCMCIA).

Yes. That's one of the many reasons you're better off with a dedicated
interface chip.
