8.3Power Consumption Specifications

Power consumption on any highly integrated device is extremely dependent on the operating voltage, external switching activity, and external loading (shown in Table 8-3, “Power Consumption Specifications” on page 8-3). Because power consumption on the applications processor is optimized, power varies based on which functions are being performed and by the data and frequency requirements of the module.

The maximum power consumption specification is determined by all units running at their maximum: processor speed, voltage, and loading conditions. This method generates a conservative power consumption value; however, power supply and thermal management design requires the highest possible power consumption for robust design.The applications processor’s maximum power consumption is calculated using the following conditions:

•All peripheral units operating at maximum frequency and size configuration

•All I/O loads maximum (50pF for Memory interface, 100pF for peripherals)

•Core operating at worst case power scenario (hit rates adjusted for worst power)

•All voltages at maximum of range
