s METHOD OF SETTING OSCILLATOR FREQUENCY
Oscillator Frequency can be set by timing capacitor (CT) connected to CT pin (pin 1) and timing resistor (RT)
connected to RT pin (pin 2).
Oscillator frequency
• Normal mode
1000000
fOSC (kHz) =: _{CT(pF) × RT(kΩ)}
• Low power mode
100000
fOSC (kHz) =: _{CT(pF) × RT(kΩ)}
