● General
WTN6040FP-14S is developed by Shenzhen Weichuang Zhiyin Electronics Co., Ltd High power voice chip The audio output type is PWM, and the built-in class D audio power amplifier circuit can directly push a 4 ohm 3W speaker. Its output can work normally without LC filtering. It reduces EMI interference in the full bandwidth range and minimizes the impact on other components. At present, the speech length of WTN6040FP-14S is 40 seconds. The audio sampling rate is currently up to 32kHz, 16 level volume control, PWM output mode. The clock frequency of this chip is 13.1072 (± 3%) MHz. The chip can change the internal voice content of the chip online through the supporting downloader; The chip supports 1-wire and 2-wire serial communication.
● Function description
1. The working voltage is 2.0~5.5V (in order to make the power amplifier work normally, the minimum working voltage is recommended to be no less than 3.0V);
2. Audio output mode: 12bit PWM;
3. It can directly drive the 4R horn and output 3W@5V ;
4. Support audio playback of 6K~32Khz sampling rate;
5. Customers can change the internal voice content of the chip through the supporting downloader;
6. Support 1-wire serial port and 2-wire serial port;
7. Support 224 segments of address voice at most;
8. Flash type voice chip, chip master program and Flash data can be repeatedly burned.
9. 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
10. The chip is equipped with Class D audio power amplifier, with efficiency up to 88%, and no filter is required;
11. Built in short circuit protection, overcurrent protection and overheat protection;
12. Excellent full bandwidth EMI suppression capability
13. Excellent "power on/power off" noise suppression
14. Note: the PA2 pin of the chip is low at ordinary times and high at playback
● Pin description
Note: Do not add up and down to PA2, which may cause IC to enter non working mode.
● Limit parameters
Note: According to the laboratory test results of the sample, the chip can work normally at - 40 ℃~+85 ℃.
● Electrical characteristics
VCC=3.0V, Ta=25℃
Note: When the chip is playing normally and initializing, the power supply should not fluctuate more than 1.3V.
