15.2 Current Consumption
Typical current is proportional to both clock frequency and voltage. The main oscillator
requires approximately 6 mA at 5 V and 2 mA at 3 V independent of frequency. The basic
current consumption for the processor exclusive of the oscillator at 5 V and 15 MHz is
approximately 42 mA. The following formula can be used to compute the current con-
sumption:
The first term represents the current consumed by the processor, which is directly propor-
tional to voltage and frequency. The second term is the current consumed by the main
oscillator, which is approximately independent of frequency, but varies as the square of
the voltage. This term is zero when the main oscillator is disabled. Some checkpoints for
current consumption are provided in Table 15-8.
The current consumed by memory and other devices included in the system, including
pullup resistors, outputs driving a load, and floating inputs, must be added to the figures in
Table 15-8.
