WTN7 SOP8/ DIP8 Pin Voice ICs

Product Description:

WTN7 voice ICs are similar with WTN6 sound chip.

There are two kinds now (WTN7080,WTN7170 ); the voice length is 80s and 170s, much longer than WTN6 sound chips (WTN6 voice length is only 40s), both package are sop8 and dip8 pin.The audio sample rate can up to 44.1kHZ maximally,16-level volume control.

WTN7 chip output mode is PWM, without DAC output. But WTN6 voice IC chip has both PWM and DAC output.

PWM output can drive 8R/0.5W speaker, Accurate +/-1% internal shock, no need to have external shock, super-low power consumption in standby mode.

Functions:

△Working voltage: 2.8V~5.2V.

△Long voice length, 80s and 170s for option.

△In standby mode, quiescent current less than 5uA.

△Accurate+/-1% internal shock

△With the function of low voltage reset (LVR=1.8V), watchdog timekeeping and I/O reset.

△PWM audio output, able to drive 8Ω/0.5W speaker and buzzer directly.

△Built in watchdog.

△Serial port control mode: one-line serial port, two-line serial port (can load 224 pieces of voice at most, more details later).

△Support output function in BUSY state.

Note:

The control mode and output mode have been set when writing program, can not be changed. Please tell me about the application requirements before customizing our chips.

One-line serial port communication:

In one-line serial port mode, can use MCU to control and send data to WTN7 series voice IC chip through DADA line to have voice play, stop, circulate and so on.

Two-line serial port communication:
