Release B
This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
4.1 DC Characteristics
Notes:
1. MHz ratings refer to CPU clock frequency.
2. Not 100% tested.
4.1 AC Characteristics
Table 4.4 through Table 4.9 list the AC character-
istics including output delays, input setup require-
ments, input hold requirements and output float
delays. These measurements are based on the
measurement points identified in Figure 4.1. The
rising clock edge reference level VREF , and other
reference levels are shown in Table 4.3 below for
the STPC Consumer-S. Input or output signals
must cross these levels during testing.
Figure 4.1 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 4.1.
