4.5.1
This block implements an amplifier that when combined with a suitable quartz crystal and external load
capacitors implements an oscillator. It also implements a power mux such that the oscillator can be pow-
ered from VDD1P1 or VDD_SOC. VDD_1P1 should be the cleaner supply and is the preferable choice,
but if the oscillator is needed to run in "stop mode" then it is necessary to run from VDD_SOC, which is
0.9 V in stop mode.
The system crystal oscillator consists of a Pierce-type structure running off the digital supply. A straight
forward biased-inverter implementation is used.
4.5.2
This block implements an amplifier that when combined with a suitable quartz crystal and external load
capacitors implements a low power oscillator. It also implements a power mux such that it can be powered
from either a ~3 V backup battery (VDD_SNVS_IN) or VDD_HIGH_IN such as the oscillator consumes
power from VDD_HIGH_IN when that supply is available and transitions to the back up battery when
VDD_HIGH_IN is lost.
In addition, if the clock monitor determines that the OSC32K is not present, then the source of the 32 K
will automatically switch to a crude internal ring oscillator. The frequency range of this block is
approximately 10–45 kHz. It highly depends on the process, voltage, and temperature.
The OSC32k runs from VDD_SNVS_CAP, which comes from the VDD_HIGH_IN/VDD_SNVS_IN
power mux. The target battery is a ~3 V coin cell. Proper choice of coin cell type is necessary for chosen
VDD_HIGH_IN range. Appropriate series resistor (Rs) must be used when connecting the coin cell. Rs
depends on the charge current limit that depends on the chosen coin cell. For example, for Panasonic
ML621:
For a charge voltage of 3.2 V, Rs = (3.2-2.5)/0.6 m = 1.17 k
