Product Description:
WTN6 series sound chip is 4-bit controller. At present there are three kinds of chip: WTN6010, WTN6020, WTN6040, WTN6090 (voice length is 10s,20s,40s,90s independently). WTN6040 and WTN6090 have been put into market. WTN6010 and WTN6020 will come soon. The package of WTN6 sound ICs are sop8 and dip8. Audio sample rate is up to 64 kHz 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.
Functions:
△Working voltage: 2.8V~5.2V.
△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; 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 224 pieces of voice at most, more details later).
△Support output function in BUSY state.

Limited Parameters:
One-line serial communication:
In one-line serial port mode, can use MCU to control and send data to WTN6 series through DADA line to have voice play, stop, circulate and so on.
Two-line serial port communication
Two-line serial port control mode is controlled by CLK and DATA. Each time send one byte of data, clock signal CLK line is pulled low from 4ms to 40ms. It is recommended to use 5ms to wake up WTN6 sound IC chip; for receiving data, low bit first, receiving at the clock rising edge. Clock cycle is between 40us～3.2ms. 300us is recommended. When sending data, low bit data first, high bit data next.00H～CFH is audio address command. E0H～EFH is volume adjustment command. F2H is loop playback command. FEH is command to stop playing.
