3.4 DC Characteristics
Notes:
1. MHz ratings refer to CPU clock frequency.
2. Not 100% tested.
3.5 AC Characteristics
Table 7 through Table 12 list the AC characteris-
tics including output delays, input setup require-
ments, input hold requirements and output float
delays. These measurements are based on the
measurement points identified inFigure 8and Fig-
ure 9. The rising clock edge reference level VREF
, and other reference levels are shown inTable 6
below for the STPC Consumer. Input or output
signals must cross these levels during testing.
Figure 8 shows output delay (A and B) and input
setup and hold times (C and D). Input setup and
hold times (C and D) are specified minimums, de-
fining the smallest acceptable sampling window a
synchronous input signal must be stable for cor-
rect operation.
Note: Refer to Figure 8.
