Can I use Spansion parallel flash devices with the Active Parallel (AP) configuration scheme in Cyclone III or Cyclone IV devices?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

No, Spansion parallel flash devices are not supported by the AP configuration scheme. This is because the AP scheme relies on flash access being synchronous to DCLK generated by the Cyclone® III or Cyclone IV device, and therefore requires the parallel flash device to have a clock input. Spansion parallel flash devices do not have clock inputs.

The only supported flash devices are the Numonyx StrataFlash® Embedded Memory P30 flash family and the Numonyx StrataFlash Embedded Memory P33 flash family.
