8.12.3.4 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	V_CC	TYP	UNIT
f_VLO	VLO frequency	Measured at MCLK	3 V	10	kHz
df_VLO/d_T	VLO frequency temperature drift	Measured at MCLK⁽¹⁾	3 V	0.5	%/°C
df_VLO/dV_CC	VLO frequency supply voltage drift	Measured at MCLK⁽²⁾	1.8 V to 3.6 V	4	%/V
f_VLO,DC	Duty cycle	Measured at MCLK	3 V	50%

(1) Calculated using the box method: (MAX(–40°C to 85°C) – MIN(–40°C to 85°C)) / MIN(–40°C to 85°C) / (85°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 8.12.3.4).

Section 8.12.3.5 lists the characteristics of the MODCLK.
