During voice playback, an external resistor is connected between this pin and the VDD pin to set the

sampling frequency. Or keep OSC floating if choosing INT-Rosc.

Note : External resistor is 68K Ω.

•

VPP :

During voice playback, this pin and VSS must be connected together to the power ground.

In Circuit Program : This pin is connected to a separate 8.5V power supply voltage for OTP

programming. Connect resistor between power ground and VPP.

Note : Resistor is 10K Ω.

•

OUT1, OUT2 and OUT3 :

OUT1,OUT2 and OUT3 can select output function as below :

1. Busy- H : When voice is playing, output high level signal.

2. Busy- L : Inverted output of Busy- H.

3. LED- Flash : When voice is playing, output LED flash pulse.

4. ~LED- Flash : Inverted output of LED- Flash.

5. Stop- H : When voice plays finished, output stop pulse.

6. Stop- L : Inverted output of Stop- H.

7. Load : After load voice data to buffer success, output logic high signal.

8. Prog-Busy - H : When voice of Prog-Busy set 1, high pulse output.

When voice of Prog-Busy set 0, low pulse output.

9. Prog-Busy - L : Inverted output of Prog-Busy - H.

•

COUT :

16-bits current mode DAC output for voice playback.

•

RST :

Chip reset in playback mode.

External reset pull high a capacitor if used internal reset not. capacitor :100nF
