Power Consumption Specifications
Power consumption depends on the operating voltage, peripherals enabled, external switching
activity, and external loading.
Specifying maximum power consumption requires all units to be run at their maximum
performance, and at maximum voltage and loading conditions. The maximum power consumption
of the PXA255 processor is calculated using these conditions:
All peripheral units operating at maximum frequency and size configuration
All I/O loads maximum (50 pF)
Core operating at worst-case power scenario (hit rates adjusted for worst power)
All voltages at maximum of range. Maximum range for the core voltage is set to maintain
compatibility with the PXA250.
Maximum case temperature
Do not exceed the maximum package power rating or Tcase temperature.
Since few systems operate at maximum loading, performance, and voltage, a more optimal system
design requires more typical power-consumption figures. These figures are important when
considering battery size and optimizing regulator efficiency. Typical systems operate with fewer
modules active and at nominal voltage and load. The typical power consumption for the PXA255
processor is calculated using these conditions:
SSP, STUART, USB, PWM, Timer, I2S peripherals operating
