Notes:
1. In principle, the playing speed determined by Rosc should correspond to the sampling rate during the coding phase. The
playing speed may be adjusted by varing Rosc, however.
2. Rs is an optional current-dividing resistor. If Rs is added, the resistance should be between 390 and 820 ohm.
3. The typical Rosc = 750 Kohm for 3 MHz Fosc; and Rosc = 1.6 Mohm for 1.5 MHz Fosc.
4. Cs is optional.
5. The DC current gain of the NPN transistor ranges from 120 to 200.
6. All unused trigger pins can be left open because of their internal pull-high resistance.
7. The OSC layout in customer’s PCB should be as closed as the OSC pad to avoid noise coupling.
8. The chip’s substrate must be wired to Vss.
9. W523A008~A010’s trigger pins are TG1, TG2, TG3, TG4; W523A012~W523A120’s trigger pins are TG1, TG2, TG5, TG6.
