POWER DISSIPATION
Total power dissipation has two components: one due to inter-
nal circuitry (P
INT
) and one due to the switching of external
output drivers (P
EXT
).
Table 32
shows the power dissipation for
internal circuitry (V
DDINT
). Internal power dissipation is depen-
dent on the instruction execution sequence and the data
operands involved.
The external component of total power dissipation is caused by
the switching of output pins. Its magnitude depends on:
Number of output pins (O) that switch during each cycle
Maximum frequency (f) at which they can switch
Their load capacitance (C)
Their voltage swing (V
DDEXT
)
The external component is calculated using:
The frequency f includes driving the load high and then back
low. For example: DATA15–0 pins can drive high and low at a
maximum rate of 1/(2
t
SCLK
) while in SDRAM burst mode.
A typical power consumption can now be calculated for these
conditions by adding a typical internal power dissipation:
Note that the conditions causing a worst-case P
EXT
differ from
those causing a worst-case P
INT
. Maximum P
INT
cannot occur
while 100% of the output pins are switching from all ones (1s) to
all zeros (0s). Note, as well, that it is not common for an applica-
tion to have 100% or even 50% of the outputs switching
simultaneously.
