Low Power Features

The Intel Celeron M processor incorporates the DPWR# signal that controls the data bus input
buffers on the processor. The DPWR# signal disables the buffers when not used and activates
them only when data bus activity occurs, resulting in significant power savings with no
performance impact. BPRI# control also allows the processor address and control input buffers to
be turned off when the BPRI# signal is inactive. The On-Die termination on the processor FSB
buffers is disabled when the signals are driven low, resulting in additional power savings. The low
I/O termination voltage is on a dedicated voltage plane independent of the core voltage, enabling
low I/O switching power at all times.
Processor Power Status Indicator (PSI#) Signal
The Intel Celeron M processor incorporates the PSI# signal that is asserted when the processor is in
a low power (Deep Sleep ) state. This signal is asserted upon Deep Sleep entry and deasserted upon
exit. PSI# can be used to improve the light load efficiency of the voltage regulator, resulting in
platform power savings and extended battery life.
