It is fabricated with Standard CMOS processwith embedded voice storage memory. It can store from 10 to 341 sec voice message with 4-bitADPCM compression at 6KHz sampling rate. 8-bit PCM is also available as user selectable option toimprove sound quality. Depending on IC body, there are up to twelve programmable I/O pins. Keytrigger and Parallel CPU trigger mode can be configured according to different application requirement.User selectable triggering and output signal options provide maximum flexibility to various applications.Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker drivingoutput minimize the number of external components.Voice Chip/IC - 42sec recording sound/music chip/IC+8bit MCU,aIVR4208-SOP16
