The typical value of Rosc is 150 Kfor 8MHz and 300 Kfor 4MHz and should be connected to GND (VSS).
Please refer to design guide to get typical Rosc value for each part number.
For W567S301~S341, VSSA and VSSOSC should be connected to VSS; and VDDA and VDDOSC should be
connected to VDD in PCB layout.
For W567S301~S341, VDDA must still be connect to VDD to keep normal standby current, if dont need ADC module
application.
The Rs value is suggested in 270~ 1Kto limit too large DAC output current flowing into transistor.
The 10and 0.1F between VDD, VDDOSC and GND are optional to filter power noise.
The capacitor, 4.7F, 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.
