C
= load capacitance,
f
= output switching frequency.
E xample:
In an application where external data memory is used and no
other outputs are active, power dissipation is calculated as
follows:
Assumptions:
External data memory is accessed every cycle with 50% of the
address pins switching.
External data memory writes occur every other cycle with
50% of the data pins switching.
Each address and data pin has a 10 pF total load at the pin.
T he application operates at V
