8.12.3.5 Internal Very-Low-Power Low-Frequency Oscillator (VLO)

over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
PARAMETER TEST CONDITIONS VCC TYP UNIT
fVLO VLO frequency Measured at MCLK 3 V 10 kHz
dfVLO/dT VLO frequency temperature drift Measured at MCLK(1) 3 V 0.5 %/°C
dfVLO/dVCC VLO frequency supply voltage drift Measured at MCLK(2) 1.8 V to 3.6 V 4 %/V
fVLO,DC Duty cycle Measured at MCLK 3 V 50%
(1) Calculated using the box method: (MAX(–40°C to 105°C) – MIN(–40°C to 105°C)) / MIN(–40°C to 105°C) / (105°C – (–40°C))
(2) Calculated using the box method: (MAX(1.8 V to 3.6 V) – MIN(1.8 V to 3.6 V)) / MIN(1.8 V to 3.6 V) / (3.6 V – 1.8 V)
Note:

The VLO clock frequency is reduced by 15% (typical) when the device switches from active mode to LPM3 or LPM4, because the reference changes. This lower frequency is not a violation of the VLO specifications (see Section 8.12.3.5).
