Max II EMP570 CPLD worst case current draw

Hello everybody,

I have seen charts where the Max II EMP570 CPLD current draw is shown

for the freq I am running ( 50 Mhz ) I estimate 30 mA. This is given as a typical value, does anyone know what the difference may be for worst case at the same freuquency ? Only variant I am thinking of is max temperature of 125 C, I assume typical is 25 C.

Thanks a bunch in advance,

Eric

    Dynamic power consumption is mainly caused by internal device capacitances. They neither have much temperature nor production dependency. But there isn't much use of guessing unspecified parameters.
