Taidacent WTV040-20SS PWM DAC Output OTP Sound Generator Programmable Audio Recording Chip Voice Recorder and Playback Ic 

Programmable One-Time Programming (OTP) voice chip.
At 6KHZ frequency, the voice length can reach 40 seconds, 80 seconds, and 170 seconds, respectively, depending on the chip model.
Built-in 16bits DAC digital/emulation converter, PSG speech synthesizer and sound quality optimization algorithm can display relatively high quality audio.
Two audio output modes, PWM and DAC. Silence can be inserted arbitrarily without taking up voice space.
The same voice can be called repeatedly without taking up voice space.
A variety of working modes: button control mode, button combination control mode, parallel port control mode, serial port control mode, and so on.
When playing a voice, the BUSY pin can set the output high or low level as needed.
Built-in 0.5W speaker Direct-Drive, no need for external devices, better sound quality and volume than traditional Cout thirteen tubes, and less power consumption.
Operating voltage range: 2.5V to 3.6V.
In the power saving mode, the power consumption is 2uA. In the power saving mode, the chip automatically sleeps 1 second after the chip is powered on or 1 second after the voice stops playing.
DIP16, SOP16, SSOP20, QFP44 and other package options are available.
Powerful programmability, you can customize a variety of complex functions as needed.
