Z8Plus OTP Microcontroller
LC OSCILLATOR
The Z8Plus oscillator can use an inductor capacitor oscil-
lator (
The frequency stays stable over
oscillation frequency is determined by the equation:
where
is the total series capacitance including parasitics.
Simple series capacitance is calculated using the equation
at the top of the next column.
