WTN5 Voice OTP IC

Feature:

☆PWM audio output, able to drive speaker and buzzer directly; DAC audio output, able to have external amplifier.

☆Built in watchdog.

☆With serial port control mode: one-line serial port, two-line serial port (can load 255 pieces of voice at most).

☆Support output function in BUSY state.

适用范围:

最好选择双头或三头甚至四头的旋转式剃须刀。对于过敏性肤质的男士来说，选择剃须刀也跟女人选择化妆品一样谨慎。业内人士表示，镍是最为常见的过敏原，在皮肤破损时，细菌的感染、过多的摩擦都可以增加镍的吸收，因此，有些电动剃须刀的电震颤虽然可起到震颤按摩、疏通经络气血、增强口唇周围和面颊区域活力的作用，但是少数男士使用后，口旁的皮肤会痒上一阵子，这可能与接触电动剃须刀中所含的镍有关。

1. Overview

WTN5 series is 4-bit controller. Now there are three kinds of chip WTN5055, WTN5025, WTN5085(voice length is 55s, 25s, 85s respectively), WTN5055, WTN5085 have been put into market. Next WTN5025 will come soon. Audio sample rate is up to 44.1kHz maximally,16-level volume control. Two audio output modes: PWM output and DAC output. Accurate +/-1% internal shock, no need to have external shock, ultra-low power consumption in standby mode.

2. Functions

☆Working voltage: 2.2V~5.5V.

☆In standby mode, quiescent current less than 1uA.

☆Accurate+/-1% internal shock, also providing external shock for speed governing, with the function of low voltage reset(LVR=1.8V), watchdog timekeeping and I/O reset.

☆PWM audio output, able to drive speaker and buzzer directly; DAC audio output, able to have external amplifier.

☆Built in watchdog.

☆With serial port control mode: one-line serial port, two-line serial port (can load 255 pieces of voice at most).

☆Support output function in BUSY state.

The setting of chip voltage determines the opening and closing of the internal LDO. Pay attention to chip voltage setting which must be matched with power supply voltage and circuit wiring. Otherwise it will cause chip damage or inoperation. Supply voltage is as below:
