current drive capability of cyclone II EP2C20F484C7 FPGA

hey, 

 

For driving a simple LED i need a maximum current of 30mA. Does the mentioned FPGA can support this from the GPIO pins? i would like to know the max current can be suplied by each GPIO pin, didnt find it in the manuals/ datasheets, can someone refer me to this information? 

In addition, i use in my project only 2 pins for output, is there a way in this case to get a higher current from the pins i use (by shorting other pins together with them for example)? 

 

thanks in advance

Refer to the 'DC Guidelines' section on page 10-32 of the "cyclone ii device handbook (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/cyc2/cyc2_cii5v1.pdf)". It'll comfortably do what you need. 

 

Doubling up pins for greater current capacity isn't recommended. However, many have done it before... 

 

Cheers, 

Alex
