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 8-2 PXA250 and PXA210 Applications Processors Design Guide
Power and Clocking Since few systems operate at maximum loading, performance, and voltage, a more optimal system design requires more typical power consumption parameters. These parameters are important when considering battery size and optimizing regulator efficiency. Typical systems operate with fewer modules active and at nominal voltage and load. Typical power consumption for the applications processor is calculated using these conditions: • SSP, STUART, USB, PWM, Timer, I2S peripherals operating • LCD enabled with 320x240x16bit color • MMC, AC97, BTUART, FFUART, ICP, I2C peripherals disabled • I/O loads at nominal (35pf for all pins) • Core operating at 98% Instruction Hit Rate, 95% Data Hit Rate • All voltages at nominal value The individual power supply specifications add up to more than the total because the operating conditions which cause maximum power consumption on each supply are sometimes mutually exclusive.

Power <strong>and</strong> Clocking<br />
Since few systems operate at maximum loading, performance, <strong>and</strong> voltage, a more optimal system<br />
design requires more typical power consumption parameters. These parameters are important when<br />
considering battery size <strong>and</strong> optimizing regulator efficiency. Typical systems operate with fewer<br />
modules active <strong>and</strong> at nominal voltage <strong>and</strong> load. Typical power consumption for the applications<br />
processor is calculated using these conditions:<br />
• SSP, STUART, USB, PWM, Timer, I2S peripherals operating<br />
• LCD enabled with 320x240x16bit color<br />
• MMC, AC97, BTUART, FFUART, ICP, I2C peripherals disabled<br />
• I/O loads at nominal (35pf for all pins)<br />
• Core operating at 98% Instruction Hit Rate, 95% Data Hit Rate<br />
• All voltages at nominal value<br />
The individual power supply specifications add up to more than the total because the operating<br />
conditions which cause maximum power consumption on each supply are sometimes mutually<br />
exclusive.<br />
