The typical value of Rosc is 150 KΩ for 8MHz and 300 KΩ for 4MHz and should be connected to GND (VSS).

Please refer to design guide to get typical Rosc value for each part number.

For W567S080~S341, VSSOSC should be connected to VSS; and VDDOSC should be connected to VDD in PCB

layout.

The Rs value is suggested in 270Ω ~ 1KΩ to limit too large DAC output current flowing into transistor.

The 10Ω and 0.1µF between VDD, VDDOSC and GND are optional to filter power noise.

The capacitor, 4.7µF, shunts between VDD and GND is necessary as power stability. But the value of capacitor is

depend on the application.

The above application circuits are for reference only. No warranty for mass production.
