5.4 Power Consumption
The standby mode is obtain by specifically turning off the different clocks, i.e. it is not
just a simple bit to flip into a register. Once all the clocks have been shutdown the
power dissipation is at most 300 mW (includes leakage current) at 85 ˚C (case
temperature).
The power consumption of the PNX15xx Series is dependent on the activity of the
TM3260, 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 PNX1500 system:
Example:
savings).
Typical power consumption for typical applications on PNX15xx Series is expected to
ranges from 1.2 W to 2 W.

speed which is not what a real application will do. Board design, i.e. decoupling and
regulators, should plan for peak current. Peak currents are possible for few cycles it is
not sustained current consumption. These peaks will be averaged out by the
decoupling capacitors, but regulators should also not be under-dimensioned.

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 PNX1500 system with the adjusted clock speeds for each active module.
This can include dynamic tuning to the TM3260 speed.
