Since Altera seems to be active in this group, I will ask the question
here. I have finally gotten an acceptable price on the EP1K30 part (5
volt tolerant) and will be using it in my design provided I don't step
on any landmines looking at the data sheet in fine detail. One item
that is missing is the startup current. I called support and got a
number of 194 mA. But I asked if this was over temp and voltage and he
didn't know. He said he would dig up the answer and get back to me
which never happened.
So who can tell me the power-up current for the EP1K10, EP1K30, EP1K50
and EP1K100 in both commercial and industrial temp grade over
temperature and voltage?
Also, I am not certain I understand the quiescent current spec on this
part. There are two values, one has a footnote...
ICC0 VCC supply current (standby)
(12) This parameter applies to -1 speed grade commercial temperature
devices and -2 speed grade industrial and extended temperature devices.
Does this mean the lower value (5 mA) without the footnote applies to
all other devices?
Am I correct in assuming that this spec is for a configured part with no
clock as well as an unconfigured part?
