1.9 Power Supply Application/Interruption Procedure
Pin capacitance is the sum of the interface block capacitance and the package characteristic capacitance.
Table 1-27 and 1-28 show the capacitance (C
B
) of the interface blocks.
The pin capacitance is calculated by the following formula:
Pin capacitance (C
T
) = interface block capacitance (C
B
) + capacitance (C
P
) of each package
