Conditions
Environment Constraints
The output delays are valid for a capacitive load of 50 pF as shown in Figure 1.
Figure 1. Output/Bidir Pad Capacitive Load
Timing Results
The output delays are for a capacitive load of 50 pF as shown in Figure 1.
In order to obtain the timing for other capacitance values, the following equation should be used.
Table 3. Derating Factor Due to Capacitive Load Variation
In the tables that follow, the output delays are for industrial conditions only.
Voltage Ranges
Although the core may be supplied between 1.8V and 3.6V, there are two voltage ranges that have been characterized for
timing purposes.
These are from 1.8V to 2.2V (core at 2V), and 2.7V to 3.6V (core at 3.3V). Timing values are given for both sets of condi-
tions, as in Table 4.
