Read data from a SD card using an Altera Max II

Hi, I want to create a little board that has a Max II cpld and a Sd Card. The Max II version I´m using is Epm240t100c5n. I want to handle the Sd cart like a normal flash chip, so I need to pass so...

Max II will handle the physical interface nicely - you'll be able to interface the SD card directly to I/O pins of the CPLD. However, the EPM240 isn't a particularly large part - it's internal resources are relatively limited. So, you'll be limited on how much functionality you can squeeze into it.

Based on what you describe, I suspect the EPM240 will have enough logic available for you to realise your goal.

Is there an easy way to implement this Sd interface?

If you know what you're doing... I'm not sure how to answer that question without knowing how you intend to implement it. Can I assume you'll be writing some rtl?

Cheers,
