Hi, 

 

I am working on MAX V 5M2210ZF324C5 device for my current project. 

I require some of the pins to be pulled up as this wasnt taken care in schematics. 

Is this possible for the present device? Please help. 

 

Regards,

Do a search for "Programmable Pull-Up Resistor" in "MAX V Device Handbook".

Yes. MAX V has programmable pull-ups. Enable/disable it under the 'Weak Pull-Up Resistor' column in the Pin Planner. 

 

Note: 

--- Quote Start ---  

The programmable pull-up resistor is active during power-up, ISP, and if the device is unprogrammed. 

--- Quote End ---  

 

 

Cheers, 

Alex

Hi, Alex:

    I can't find 'Weak Pull-Up Resistor' column in the Pin Planner. Note, I'm using Quartus Prime Lite 20.1.0.

                 Thanks!

Hi,

It's an old question but I answer anyway. That could help someone. The weak pull-up column need to be enabled before to see it. Right clic in the title barre, select "customize columns...", then select weak pullup in the left list, add it in the right list, ok. Done.
