Dynamic Characteristics
The AC specifications presented consist of output delays, input setup and hold times, and signal
skew times. All signals are specified relative to an appropriate edge of the clock and possibly to
one or more other signals.
The measurement of the AC specifications is defined by the waveforms shown in Figure 7-1. To
test the parameters guaranteed by Atmel inputs must be driven to the voltage levels specified in
the figure. Outputs are specified with minimum and/or maximum limits, as appropriate, and are
measured as shown. Inputs are specified with minimum setup and hold times and are measured
as shown. Finally, the measurement for signal-to-signal specifications are shown.
Note that the testing levels used to verify conformance to the AC specifications do not affect the
guaranteed DC operation of the device as specified in the DC electrical characteristics.
