RC Oscillator Frequency
These tables show the effects of the RC oscillator frequency as the device voltage varies. In
these measurements a capacitor and resistor value are selected and then the frequency of the
RC is measured as the device voltage varies. The table shows the typical frequency for a R and
C value at 5V, as well as the variation from this frequency that can be expected due to device
processing.
