APLUS INTEGRATED CIRCUITS INC. www.aplusinc.com.tw aMTP777 + aXLV11H dual set Solution FEATURES 150 minutes long time solution in 12KHz playback sample rate. 3.0V ~ 3.3V single power supply. 10uA low standby current. 6 KHz ~ 20 KHz playback sample rate. 8-bit resolution DAC/PWM voice output. Up to 1024 voice section. 6-wires series command or keys control. 6 levels volume control in PWM mode. DESCRIPTION aMTP777 is a MCU based voice controller IC. It can accomplish 150 minutes with aXLV11H external memory. in 12KHz sample rate. User can control by 6-wires series command or keys, and playback by 6 KHz to 20 KHz sample rate, 8-bit resolution and PWM or DAC voice output mode. Key Trigger Mode Typical Circuit Pin Descriptions In “Key Trigger Mode”, User control voice playback by 5 buttons, and select voice output mode by 1 option: 1/8 APLUS INTEGRATED CIRCUITS INC. www.aplusinc.com.tw Play/Pause (PB0) : Play/Pause key to play or pause the voice playing. Next Section (PB1) : To play next voice.. Previous Section (PB2) : To play previous voice. Reset Section (PB3) : Reset key. Volume+ (PD1) : Volume control key to offer 6 volume levels. This function only active in PWM mode. Voice Output Mode (PD2) :When power on, aMTP777 will detect PD2 status. If PD2 connect to VDD, then will be DAC output. If no connecting, it will be PWM output. 6-wires Command Mode Typical Circuit Pin Descriptions In the “6-wires Command Mode”, User control voice playback by an external microcontroller: RSTB(RSTB) : The aMTP777 will reset by drive this pin to vss. SCK (PB0) : Series clock input. PDI(PB1) : Series data input. CS(PB2) : Chip select -- command will receive when this pin drive to low voltage level. BUSY(PD1) : Chip busy -- drive to high voltage level when command latch. PLAY(PD2) : Voice playback -- drive to high voltage level when voice playing. Control Timing 2/8 APLUS INTEGRATED CIRCUITS INC. www.aplusinc.com.tw Control Command Voice Output Circuit Descriptions User can select voice output by DAC or PWM. PWM has the simplest circuit, and support digital volume control. DAC can get higher voice volume by external amplifier or transistor.
