Oscillator Period(1)
Free-Running Sawtooth Measured at Pin 12
1. Oscillator Period T (= Tr + Tf) is determined by the external components R1, R2, and C3 where Tr = (0.6931) R2 x C3 and
Tf = (0.6031) R1 x C3.
The other timing characteristics are some multiple of the oscillator timing shown in the table.
