Internal Power Domains
The external power supplies are used to generate several internal power domains, which are shown
in
and Power” section of the Intel® PXA27x Processor Family Developers Manual for more
information on internal power domains.
Table 5-6
Power-Consumption Specifications
Power consumption depends on the operating voltage and frequency, peripherals enabled, external
switching activity, and external loading and other factors.
