Does Max V CPLD has inbuilt ADC or DAC. If yes then how can i interface it with CPLD. :)

It doesn't have an ADC or DAC.

As Leon points out, Altera CPLDs and FPGAs do not have ADCs and DACs. 

 

You can however create a DAC using a PWM waveform and low pass filter (Altera have an app note on this), or an ADC using an LVDS receiver (Lattice have an app note on this). 

 

There are plenty of SPI ADCs and DACs from multiple vendors. They are very simple to interface to. I can post examples. 

 

What kind of speed/update-rate were you looking for? 

 

Cheers, 

Dave

Hello! 

I bought last week max V cpld and has installed Board Test System to go through 

a design example for learning how it works. 

I wonder where I can find manuals of these design examples, i.e how/where I begin 

to start using and learning understand the design example. 

Thanks

I know this is an old posts.

Would you point me to those links?

Browse the Altera app notes:

Here's the PWM app note

Do the same on the Lattice site. The app note I was recalling is probably this one on Sigma-Delta ADCs:

This has links to a PDF and source code.
