AC CHARACTERISTICS
guaranteed across the entire processor core voltage range
of 1.6V to 2.0V (nominal). AC characteristics that are
affected significantly by the core voltage or speed grade
are documented accordingly.
The following tables list the AC characteristics including
output delays, input setup requirements, input hold require-
ments, and output float delays. The rising-clock-edge refer-
ence level V
REF
, and other reference levels are shown in
ing testing.
Input setup and hold times are specified minimums that
define the smallest acceptable sampling window for which
a synchronous input signal must be stable for correct opera-
tion.
All AC tests are performed at V
