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

over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
PARAMETER TA VCC MIN TYP MAX UNIT
fVLO VLO frequency –40°C to 85°C 3 V 4 12 22 kHz
dfVLO/dT VLO frequency temperature drift(1) –40°C to 85°C 3 V 0.5 %/°C
dfVLO/dVCC VLO frequency supply voltage drift(2) 25°C 1.8 V to 3.6 V 4 %/V
(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)
