interface, serial interface
*2, Operating voltage: DC 2.5V to 3.7V
*3, Standby current 2uA, with sleep mode to save power.
*4, SSOP*0 package is available
Description:
WTV**0SD**0S is one kind of core processing chip. It supports
MP3 control mode, key control models (*-voice and *-voice),
loop play mode and two-line serial control mode. Control mode
is set while producing, which can not be changed through
configuring.
1): MP3 control mode: Play / stop, next, last, volume +,
volume - and so on.
2): Key control mode (3 voice): One key to trigger a voice,
can play 3 pieces of voice and adjust volume. All keys are
default as no duplicate trigger for pulses.
3): Key control mode (5 voice): Three sub-control methods, 1.
Key can not be duplicate-triggered by pulse; 2. All keys are
play / stop trigger (No single recycled); 3. All keys are
Play/Stop (single can be recycled).
4): Loop play mode: After powered on, no need to trigger any
I / O port, directly play all the voice in SD card, with
functions to record playing points while power off, from
which it plays while powered on again. Two sub-control modes,
1. P*4 has pulse-triggered play/pause function; 2. P*5 has
level-triggered play/pause function.
5): Two-line serial control mode: Controlled by MCU clock via
CLK and DI data lines. Free to play voice at any address. In
this mode, it has voice combination play function.
Audio content updates directly to SD card on the PC. The
module supports FAT file system. Support AD4 of 6kHz ~ *2kHz,
*6kHz sampling rate and WAV audio of 6kHz ~ *6kHz sampling
rate.
Please notice that we can only supply two line serial control
mode by default now, thanks very much.
