1) The input and output parameter values in this table are directly related to ambient temperature and DC supply
voltage. A temperature range other Tamin to Tamax or a supply voltage range other than VDDmin to VDDmax will
affect these values and must be evaluated extra.
2) Static supply current IDDS is exclusive of input/output drive requirements and is measured at maximum VDD
with the clocks stopped and all inputs tied to VDD or VSS, configured to draw minimum current.
3) Operating current is exclusive of input/output drive requirements and is measured at maximum VDD and maxi-
mum clock frequency 20 MHz.
