描述 Description

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
? Development tools support
? Low standby current (<5 μA at 3V)
? 3.0V-6V single power supply operation
? 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
