CC2510Fx / CC2511Fx
10 Power Control
The CC2510Fx/CC2511Fx has four power modes,
called PM0, PM1, PM2 and PM3. PM0 is the
active mode while PM3 has the lowest power
consumption. The power modes are shown in
Table 25 together with voltage regulator and
oscillator options.

Table 25: Power modes
PM0: The full functional mode. The voltage
regulator to the digital core is on and either the
high speed RC oscillator or the 26/48 MHz
crystal oscillator or both are running. Either the
low power RC oscillator or the 32.768 kHz
crystal oscillator is running.
PM1: The voltage regulator to the digital part is
on. Neither the 26/48 MHz crystal oscillator nor
the high speed RC oscillator is running. Either
the low power RC oscillator or the 32.768 kHz
crystal oscillator is running. The system will go
to PM0 on reset or an external interrupt or
when the sleep timer expires.
PM2: The voltage regulator to the digital core
is turned off. Neither the 26/48 MHz crystal
oscillator nor the high speed RC oscillator is
running. Either the low power RC oscillator or
the 32.768 kHz crystal oscillator is running.
The system will go to PM0 on reset or an
external interrupt or when the sleep timer
expires. The CC2511Fx will lose all USB state
information when PM2 is entered. Thus, PM2
should not be used with USB.
PM3: The voltage regulator to the digital core
is turned off. None of the oscillators are
running. The system will go to PM0 on reset or
an external interrupt. The CC2511Fx will lose all
USB state information when PM3 is entered.
Thus, PM3 should not be used with USB.
