PIN DESCRIPTIONS :

•

S1 ~ S8 :

Input Trigger Pins:

- In Key Mode : S1 to S8 is used to trigger 57 Voice groups.

- In CPU Parallel Mode : this pin low to high [ Latch ] the address at S1(lsb) to S8(msb)

and starts the voice playback.

- In SPI Mode :

S1 is Chip Select (CSB) pin to initiate the command input.

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 :

S1:Backward. S2:Forward.

S3:(Pause/Stop).

S4:Reset.

- In aP89 Mode : similar with APLUS 1st Generation OTP IC. (aP89341/aP89170/aP89085 ) usage.

•

SBT :

Input Trigger Pin:

- In SBT Mode :This pin is trigger pin to play Voice Groups one time or looping sequentially up to

1024 Voice Groups.

- In CPU Parallel Mode : This pin is used as address strobe to latch the Voice Group address input

at S1 to S8 and starts the voice playback.

- In MP3 Mode : This pin is (Play/Pause) or (Play/Stop).

•

VDDP and VDDA :

Power Supply Pins: These two pins must be connected to the positive power supply.

•

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

between power ground and VPP.

•

M0 and M1 :

In Key Mode、SBT Mode、CPU Parallel Mode、MP3 Mode、SPI Mode、and I2C Mode ,

M0 and M1 can be used for Crystal oscillator or volume control.

In aP89 Mode Operating Mode Setting Pins:

- M1=0, M0=0 set the chip into Key Trigger Mode.

- M1=0, M0=1 set the chip into CPU Parallel Command Mode.

- M1=1, M0=0 set the chip into CPU Serial Command Mode.

•

VOUT1 and VOUT2 :

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

•
