NOTES:

1. The oscillator frequency is defined by the current flowing through the external resistor R2. The voltage at the INT pin is

drop across resistor R1. This voltage drop causes the oscillator coefficient for tb2 to be different for the two cases of INT

common R1 resistor).

2. The oscillator stability with temperature is dependent on the temperature coefficients of the external components. If the

capacitance value of the external capacitor varies more than 5% over the parametric temperature range, the figures quoted

for oscillator variation are not valid.
