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.
