• Auto-power down rectly
• VOUT1 and VOUT2 drives buzzer or speaker di-
• COUT pin drives speaker with a transistor
• Optional pop noise elimination function quality
• ADPCM data compression provides high sound
• Built-in D/A converter, EPROM
• Single external resistor to determine sample rate
• Built-in oscillator with variable sample rate Pulse, BUSY Signal, and LED
• Three programmable output pins for STP Stop
• IRP interrupt pin for master reset
• 15 ms debounce time suitable for CDS triggering option
• Holdable and unholdable, edge and level
• SBT for sequential play-all or random play
• Four trigger pins, TG1 to TG4 for eight groups
• Voice data re-use saves memory space extends the duration of playback
• Combination of voice building blocks
• Versatile features for playback
• Minimum 20 second voice length at 6 KHz
