GENERAL DESCRIPTION
API8208A is a high quality voice synthesizer capable of varying playback duration. A proprietary ADPCM algorithm is used. The audio message is stored in a 512K bits on-chip EPROM which can store up to 20 seconds of voice data at 6 KHz sample rate.

FEATURES
• Minimum 20 second voice length at 6 KHz
• Versatile features for playback
• Combination of voice building blocks extends the duration of playback
• Voice data re-use saves memory space
• Four trigger pins, TG1 to TG4 for eight groups
• SBT for sequential play-all or random play
• Holdable and unholdable, edge and level triggering option
• 15 ms debounce time suitable for CDS
• IRP interrupt pin for master reset
• Three programmable output pins for STP Stop Pulse, BUSY Signal, and LED
• Built-in oscillator with variable sample rate
• Single external resistor to determine sample rate
• Built-in D/A converter, EPROM
• ADPCM data compression provides high sound quality
• Optional pop noise elimination function
• COUT pin drives speaker with a transistor
• VOUT1 and VOUT2 drives buzzer or speaker directly
• Auto-power down
• 3.0V-6V single power supply operation
• Low standby current (<5 µA at 3V)
• Development tools support
