W536030A Datasheet, PDF (5/12 Pages) Winbond – VOICE/ MELODY / LCD CONTROLLER

  

TEST
I
Test pad. Active high with internal pull low resistor.
ROSC
I
Connect resistor to VDD pad to generate speech or melody playing clock source.
PWM1/DAC
O
While speech or melody is active , PWM1/DAC is speaker direct driving output
or DAC output controlled by voice output file.
PWM2
O
While speech or melody is active, PWM2 is another speaker direct driving output.
