Drive leds with CPLD

[Altera_Forum]

Hello, sorry form my little question about currents. 

 I'm trying to reduce the components usage of an board using a CPLD.  I wan't to control buttons, leds and logic with a MAXV, but I'm not sure how many led's can I drive using it.  I have read from the device manual that it can drive +-25mA, but it's the absolute ratings, I have found the document "an286.pdf" where they mencion limits based on a table of "Maximum Source Current Per VCCIO Group" and "Maximum Sink Current Per GNDIO Group" but I cannot find this for the MAX V CPLD in the table netither in the dc caracteristic nor the website.  I hoped to put the CPLD output, an resistor and the LED to ground, ensuring that it drives 10mA and use like 20 leds, but i'm not sure if I going out of spec or not, and I'm not sure if it best this or connect to +3.3V and sink the current.  Hopping that you could give me some points, thanks

Use sinking configuration. MaxV can handle 20mA per pin sinking without problem

--- Quote Start ---  Use sinking configuration. MaxV can handle 20mA per pin sinking without problem  --- Quote End ---   Have any limits per bank in that configuration? In an286.pdf they tell 130mA per GNDIO Bank for the MAXII, but i can't find any information about this.  Certanly I will not use too much leds, less than 20 so even that especification will be correct, but I would love to known the limits, if there is any, since in the MAXII they existed like is said in the an286.pdf

I have a MAXII board with 8 LEDs. They are from the same bank. I believe sinking current should not be problem at all.

 DC Output current can be -25 to 25 mA, so you should be good. Honestly I've used 20 year old CPLDs that could sink 16 leds.

As a first guess, I would assume that the AN286 specifications apply for MAX V as well.
