FEATURES
● Standard CMOS process.
● Embedded 8M/4M/2M EPROM.
● 341/170/85 sec Voice Length at 6KHz sampling and 4-bit ADPCM compression.
● Maximum 254 voice groups.
● Combination of voice blocks to extend playback duration.
 ●7680 table entries are available for voice block combinations.
● User selectable PCM or ADPCM data compression
● Three triggering modes are available (controlled by M1 and M0 input pins):
   - Key Trigger Mode (M1=0, M0=0) - S1 ~ S8 to trigger up to 32 voice groups; SBT
   to trigger up to 254 voice groups sequentially.
   - CPU Parallel Trigger Mode (M1=0, M0=1) – S[8:1] services as 8-bits address to
  trigger up to 254 voice groups with SBT goes HIGH to strobe the address bits.
  - CPU Serial Command Mode (M1=1, M0=0) – user commands are clocked serially
   into the chip which enable user to fully control the operation of the chip.
● Voice Group Trigger Options: Edge / Level; Hold / Un-hold; Retrigger / Non-retrigger.
● Whole Chip Options: Ramp / No-ramp; Output Options; Long / Short debounce time.
● Optional 16ms or 65us (@ 8KHz sampling rate) selectable debounce time
● RST pin set to HIGH to stop the playback at once
● Three user programmable outputs for STOP pulse, BUSY signal and flashing LED.
● Built-in oscillator to control sampling frequency with an external resistor
● 2.2V – 3.6V single power supply and < 5uA low stand-by current
● PWM Vout1 and Vout2 drive speaker directly
● D/A COUT pin drives speaker through an external BJT
● Development System support voice compilation.
