Is EPCS4 enough for EP4CE6E22C8N?

Hello, could not find any directly table but looking at the documentatiom i could assume that a EP4CE6E22C8N bitstream can fit on a EPCS4. Is that correct?

Also lookinh at the forum i could see that M25P16 ans M25P40 work as directly replacemnt for EPCS16 and EPCS4. Is that also correct?

Best regards,

LR

    According to {url=http://www.altera.com/literature/hb/cyclone-iv/cyiv-51008.pdf]this document[/url], page 8-4, the uncompressed data stream to configure an EP4CE6 is 2,944,088 bits, so it will fit in an EPCS4. Please note that the file size can be smaller if you use compression, but on the other hand if you plan to add a software image to the EPCS you will need extra space for that too, so it depends on your usage.

    I can confirm that I've used the M25P16 and M25P40 as replacements for the EPCS16 and EPCS4.

    Note these will only operate down to 2.7V.

    I'm still looking for a 2.5V config prom to replace the EPCS16.

    :-(

    Nial.
