PIN DESCRIPTIONS :

S2 ~ S3

Input Trigger Pins:

- In Key Mode :S2 and S3 is used to trigger 3 Voice groups.

- In SPI Mode :

S2 is the Serial Clock (SCK) pin which clocks the input command and data bits into the chip.

S3 is the Data In (DI) pin in which command and data bits are shifted input into the chip.

- In I2C Mode :

S2 is the Serial Clock (SCK) pin which clocks the input command and data bits into the chip.

S3 is the Data In (DI) pin in which command and data bits are shifted input into the chip.

- In MP3 Mode :

S2 :Forward.

S3:Stop.

SBT

Input Trigger Pin:

1024 Voice Groups.

- In SPI Mode : SBT is Chip Select (CSB) pin to initiate the command input.

- In I2C Mode : SBT as output1 use.

- In MP3 Mode: SBT pin is (Play/Pause) or (Play/Sop).

VDD

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.

VSS

Power Ground Pins : VSS and VPP pins must be connected together to the power ground during

voice playback.

In Circuit Program : VSS and VPP pins must be separated to the power ground. Connect resistor

VOUT1 and VOUT2

14-bits PWM output pins which can drive speaker and buzzer directly for voice playback.

COUT

16-bits current mode DAC output for voice playback.

OUT1 (When SBT pin as OUT1 use)

OUT1 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.
