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. The typical Rosc = 750 Kohm for 3 MHz Fosc; and Rosc = 1.6 Mohm for 1.5 MHz Fosc.

3. The capacity, 0.1uF~10 uF, is necessary to reduce voltage fluctuation while PWM outputting.

4. All unused trigger pins can be left open because of their internal pull-high resistance.

5. The OSC layout in customer’s PCB should be as closed as the OSC pad to avoid noise coupling.

6. The chip’s substrate must be wired to Vss.

7. W523A008~A010’s trigger pins are TG1, TG2, TG3, TG4; W523A012~W523A120’s trigger pins are TG1, TG2, TG5, TG6.
