Integrated Circuits Inc. aP8842 VOICE
Features Voice Length Combination voice building blocks extends duration playback Voice data re-use saves memory space Maximum voice groups trigger pins, voice groups group1 sequential playblack rest voice groups mode trigger trigger mode trigger voice groups Holdable, Unholdable, Edge, Level triggering option Debounce time 22ms both mode sampling rate interrupt master reset General Description aP8842 high quality voice synthesizer capable varying playback duration. proprietary ADPCM algorithm used. audio message stored bits on-chip EPROM which store seconds voice data sample rate. aP8842 eliminates need complicated circuitry voice playback still achieves high voice quality different kind sounds. Combinations sections achieve longer playback duration. pair output pins, VOUT1 VOUT2 provides direct drive buzzer speaker. current output pin, COUT, enables device drive speaker through cost transistor. complex filtering amplifier circuit needed. automatic ramp-down function eliminates undesired noise playback. programmable Outputs stop pulse, BUSY LEDs Built-in oscillator with single external resistor determine sampling rate Built-in converter, EPROM ADPCM data compression provides high sound quality Optional noise elimination function COUT drives speaker with transistor VOUT1 VOUT2 drives buzzer speaker directly Auto-power down 2.7V 3.8V single power supply operation standby current (<5uA Development Tools Support

Group sections voice memory aP8842 subdivided into memory blocks. combination playback these memory blocks will form individual voice group. maximum groups available with triggering pins together with trigger mode. trigger mode, pins used trigger beginning voice groups. rest voice groups triggered sequentially with pin. Group Configuration Data within each group combinations different fixed memory blocks blocks. They fundamental building blocks arranging playback without limiting sequencing. This provides flexibility allows data re-used, beneficial applications with many repeated sounds words. example group configuration illustrated below: Group Group Group Group Group Section entry Block Block Block Block Block Block Block Block Block Block Block Block
entries blocks each group truly random without limitation. However, there limit total number entries voice groups, which entries aP8842. acceptable allocate entries into only group distribute other groups. depends many groups messages required. Programmable Options Each groups aP8842 have independent options. They are: Edge Level trigger Unholdable Holdable trigger Re-triggerable non-retriggerable Outputs programmable LED1, LED2, BUSY STOP pulse
Options that affect voice groups called whole chip options. They are: trigger mode trigger mode Ramp enable (for Cout drive) Ramp disable (for Vout drive)

Output Selections There three independent output pins OUT1, OUT2 OUT3, available four combinations LED1, LED2, STOP BUSY signals each voice group. Options OUT1 LED2 STOP LED1 LED1 OUT2 LED1 LED1 BUSY BUSY OUT3 BUSY LED2 STOP /BUSY
LED1 LED2 complemented outputs flashing interval. STOP pulse gives long enough positive pulse playback each group with option enable disable BUSY active high during voice playback. Software Support those Options Output selections with dedicated compiler programmer software supplied APLUS. trigger mode trigger mode trigger mode, will trigger eight voice groups. rest voice groups only triggered sequential trigger pin. trigger mode, binary data input through high pulse input with pulse width equal longer than debounce time strobe data initial playblack.
