summary
WTN6 F series is a low-cost, high-performance CMOS voice chip. The biggest feature is repeatable burning 。 The existing WTN6020-8S-F-B with a voice length of 20s and WTN6040-8S-F-B with a voice length of 40s, WTN6040-8S-F-B supports the replacement of downloader , there is 100KB voice space. The audio sampling rate is currently up to 32kHz, 16 level volume control, PWM output mode. The chip works in a wide voltage range of 1.8V~5.5V.
Function description
(1) Working voltage: 1.8V~5.5V;
(2) Reset condition: low voltage reset (LVR=1.7V) or power-off reset;
(3) 12 bit PWM pure audio output can directly drive 8 Ω/0.5W horn;
(4) It supports 1-wire serial port and 2-wire serial port control (up to 224 voice segments can be loaded, which will be explained later)
(5) Support BUSY status output (the standard program BUSY pin defaults to high level, and low level during voice playback. In addition, in the serial port control mode, the BUSY pin level changes only when the voice chip receives the correct voice address timing);
(6) After the chip plays, and the I/O port (DATA and CLK) keeps the level stable (both high and low levels are available) for 1s, the chip goes into sleep
Note for model selection:
1. Because the WTN6 needs a certain initialization time (about 100MS) to power on, and cannot respond to commands during initialization, it needs to complete initialization to receive control commands normally.
2. Using 4R speakers or parallel speakers may cause the chip PWM to appear LATCH-UP phenomenon, which will result in failure to play. It needs to be powered on again to recover, and the chip may be burned in serious cases.
3. WTN6 chip line serial port controls PWM output DEMO board playing effect and communication timing Demo video (click the link to watch) :
