MAXIMUM LOAD DERATING
All maximum delay numbers should be increased by
0.035 ns for every pF of load (up to a maximum of 150
pF) over the maximum load specified in Table 35, “Pin
List Summary,” on page A-12.
POWER SUPPLY CURRENT
For the following typical system specification shown in
Figure 13, I
system clock. The typical system is measured while the
system is executing code in a typical application with
nominal voltage and maximum case temperature.
Actual power supply current is dependent on system
design and may be greater or less than the typical I
figure presented here.
Typical current in Figure 13 is given by:
Please note that dynamic I

buffer logic, and capacitive/resistive loading of the out-
puts. For these I
