Electrical Characteristics
4.5
4.5.1
This block implements an amplifier that when combined with a suitable quartz crystal and external load
capacitors implements an oscillator. The oscillator is powered from NVCC_PLL_OUT.
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 VDDHIGH_IN such as the oscillator consumes
power from VDDHIGH_IN when that supply is available and transitions to the back up battery when
VDDHIGH_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 supply, which comes from the
VDDHIGH_IN/VDD_SNVS_IN. The target battery is a ~3 V coin cell. Proper choice of coin cell type is
necessary for chosen VDDHIGH_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

Typ
Max
This frequency is nominal and determined mainly by
the crystal selected. 32.0 K would work as well.
The 4 μA is the consumption of the oscillator alone
(OSC32k). Total supply consumption will depend on
what the digital portion of the RTC consumes. The
ring oscillator consumes 1 μA when ring oscillator is
inactive, 20 μA when the ring oscillator is running.
Another 1.5 μA is drawn from vdd_rtc in the
power_detect block. So, the total current is 6.5 μA on
vdd_rtc when the ring oscillator is not running.
