5.3 Standby Power Consumption
5.4 Power Consumption
Leakage current is a new variable of the advanced CMOS processes. Leakage
current is exponential with respect to temperature. The maximum current and power
resultant of leakage is presented in
Table 14: Current and Power Consumption Induced by Leakage
taken at 85 ˚C (case temperature). This high leakage current will not be present in
each chips but it needs to be taken into account during board design.
Standby power consumption is entirelly dominated by the leakage current.
The power consumption of the PNX17xx Series is dependent on the activity of the
TM5250, the number of modules operating, the frequencies at which the system is
running, the core voltage, as well as the loads at board level on each pin. For these
reasons it is difficult to provide precise power consumption numbers.
Three main techniques can be applied to reduce the ‘Out of the Box’ power
consumption of the PNX1700 system:

Turn off the unused modules. After reset, the modules are clocked with a 27 MHz
clock (input crystal clock, XTAL_IN). Turning off the clocks of the unused modules
significantly reduces the power consumption.
Run the PNX1700 system with the adjusted clock speeds for each active module.
This can include dynamic tuning to the TM5250 speed.
Powerdown the TM5250 every time the OS (Operating System) reaches the idle
task.
