28 / 234 page ![]() CC2430 CC2430 PRELIMINARY Data Sheet (rev. 1.03) SWRS036A Page 28 of 232 10 Power Management The CC2430 has four major 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 23 together with voltage regulator and oscillator options. Power Mode High speed oscillator Low-speed oscillator Voltage regulator (digital) A None B 32 MHz XOSC C HS RCOSC D Both A None B 32.768 kHz RCOSC C 32.768 kHz XOSC A Off B On PM0 B, C, D B, C B PM1 A B, C B PM2 A B, C A PM3 A A A Table 23: Power Modes PM0 : The full functional mode. The voltage regulator to the digital core is on and either the HS-RCOSC or the 32 MHz XOSC or both are running. Either the 32.768 kHz RCOSC or the 32.768 kHz XOSC is running. PM1 : The voltage regulator to the digital part is on. Neither the 32 MHz XOSC nor the HS- RCOSC are running. Either the 32.768 kHz RCOSC or the 32.768 kHz XOSC 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 32 MHz XOSC nor the HS-RCOSC are running. Either the 32.768 kHz RCOSC or the 32.768 kHz XOSC is running. The system will go to PM0 on reset or an external interrupt or when the sleep timer expires. 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. Refer to section 13.10 on page 140 for a detailed description of power management. |
