What is the method for calculating resistor value?

Latest Updated:08/01/2005

Question:

For the UPD7226 LCd driver, I want to set the oscillation frequency to 80 kHz with an external resistor, but what is the method for calculating that resistor value?

Answer:

There is no calculation method, but if the power supply is 5 V and the external resistor is set to 300 kΩ, the oscillation frequency can be set to approximately 80 kHz.
