The SBT pin can be used to maximum of eight groups are available with activation sections will form an individual group for data playback. A subdivided into 126 sections. Any combination of these The voice data memory area of the API8208A can be Group of sections of playback. ramp-down function eliminates undesired noise at the end filtering or amplifier circuit is needed. An automatic speaker through a low cost NPN transistor. No complex , enables the device to drive a OUT A current output pin, C speaker. 2 provides direct drive to buzzer or OUT V 1 and OUT V from 3.0V to 6.0V. PWM digital amplifier output pins, The API8208A provides wide operating voltage range background music each from one of two different chips. external mixer in which speech can be mixed with parallel in order to achieve signal mixing without an longer voice duration. Two devices can be configured in duration. In addition, devices can be cascaded to achieve Versatile combinations in sections achieve longer playback sounds and even special sound effects can be synthesized. Sounds such as human speech, animal sounds, musical in voice playback but still achieves high voice quality. The API8208A eliminates the need of complicated circuitry voice data at 6 KHz sample rate. on-chip EPROM which can store up to 20 seconds of is used. The audio message is stored in a 512K bits varying playback duration.
