The sample oscillation circuit characteristics may differ applications. manufacturer with the following notes in your mind. For further assistance, please contact with oscillator • Since the oscillation frequency precision is affected by wiring capacity of the application board, etc., adjust the oscillation frequency on the production board. • The above oscillation frequency and the operating supply voltage range are based on the operating temperature of -10°C to +70°C. For the use with the temperature outside of the range herein, or in the applications requiring high reliability such as car products, please consult with oscillator manufacturer. • When using the oscillator which is not shown in the sample oscillation circuit characteristics, please consult with Sanyo sales personnel. Since the oscillation circuit characteristics are affected by the noise or wiring capacity because the circuit is designed with low gain in order to reduce the power dissipation, refer to the following notices. • The distance between the clock I/O terminal (XT1 terminal XT2 terminal) and external parts should be as short as possible. • The capacitors’ VSS should be allocated close to the microcontroller’s GND terminal and be away from other GND. • The signal lines with rapid state changes or with large current should be allocated away from the oscillation circuit.
