Cyclone III AP NOR flash compatibility

I currently have a Cyclone III design setup for AP configuration that for years now has used the Intel (now Numonyx) P33 (130nm) NOR flash for configuration. The NOR flash is now facing obsolescence ...

Hi,

I'am using the Numonyx "PC28F256P33TFA" in AP configuration for my Cyclone III.

I know the timing differences between the 130nm and the 65nm process. But the new timing is supported since Quartus Versions 9.0 and later.

If you flash the Device with the Quartus Programmer, Quartus will configure the Cyclone Device with the paralle flashloader.

The PFL contains the timing and programming algorithm to control the flash.

Since Quartus 9.0 the PFL works with the 130nm and the 65nm Flash, too.

My design runs fine with the 65nm Flash.

Regards,

Nicolas
