Querry about MAX 7000s CPLD

I would like to know the feasibility of "EPM7128slc-10" CPLD IC, whether I can use it in the application, "Using CPLD as a microcontroller I/O expander". The link regarding details is given below:

http://www.altera.com/literature/an/an265.pdf?gsa_pos=6&wt.oss_r=1&wt.oss=expander

In this link, there are maxII, max3000 and max10 CPLDs used for this application. If max 7000s can also be used in this application, then please notify me.

Thank you.

    I want to use EPM-7128 in the application of "expanding microcontroller I/O ports".

    My question is whether there is any 'limitation' in using this MAX 7000s IC in this application or not.

    Waiting for positive response.

    Simplistically, the MAX 7000 series is functionally the 'same' as the MAX 3000 series. MAX 7000 parts are slightly higher performing with greater flexibility in their I/O.

    I'd suggest, for what you're considering, you can consider the families entirely interchangeable. Therefore, the part you specified is appropriate.
