Figure 29. Oscillator frequency variation with respect to VDD

VDD = 1.8 V to 5.5 V; VSS = 0 V; Tamb = -40 °C to +85 °C; fosc = 32.768 kHz; quartz Rs = 60 kΩ; CL = 7 pF; unless otherwise

specified. All timing values are valid within the operating supply voltage and temperature range and referenced to VIL and

VIH with an input voltage swing of VSS to VDD[1].
