Overview

WTN3 series IC is single-chip CMOS speech synthesis IC, Now there are two models WTN3 040 and WTN3 080, the length of time for 40 seconds and 80 seconds (6K sample ratio). With an Input pin and two I / O pins , With accurate internal resistance shock (+ / - 1%), so no add external shock resistance, only one PWM output, there is no need plus any component. Speech synthesis method is 4-bit/5-bit Mixed Advanced LOG-PCM, with a 9-bit PWM hardware output ,can provide better sound quality.

 

Features

(1) Programmable one-time burn (OTP) voice chip;

(3) PWM audio output mode;

(4) Integrate of the internal clock oscillator, without external shock resistance;

(5) OKY1 support up to 32 segments voice;

(6) Push-button control mode, pulse-counts control mode;

(7) Trigger the anti-shake time: 20ms (keys);

(8) One input pin can select Edge / Level (edge / level), Hold / Unhold (hold / non-hold), Retrigger / Irretrigger (again trigger / not trigger) different trigger combinations;

(9) Support the playback of voice files of different sample rates;

(10) Wide operating voltage: 1.8V to 5.5V.

(11) Support low-voltage reset (LVR) function. (LVR = 1.5V)

(12). BUSY status output; (optional)

(A). Stop_Low pulse: stop playback when you send a low pulse.

(H). LED dynamic 1/2: LED dynamic flashing according to 1/2 sound level when playing (flashes with the volume effect). (I). IO1, IO2 can be arbitrarily set time of the high and low level while playback

※ Note: LED 3Hz / 6Hz / 12Hz flash is the LED flashing frequency at the 6kHz playback speed; different playback speed, the LED flashing frequency will be different.

(13) STB functions: the "long press stop" function. Can be set between 1 - 7 seconds, while playing, long press any key to set the time to stop playing, and enter power-saving state.

(14) When in IO input state, it can set anti-shake time , short trigger (50US) ,long trigger (20MS), short trigger for MCU control applications, long trigger suit for key control occasions.

 

Applications

In chips applications, it can almost used in all low-cost and does not need change the voice places, such as:

Motor Vehicles (anti-theft alarm, parking radar, GPS navigation systems, electronic dog, central locking);

 smart home system, alarm clock, reminder;

special use alarm, home burglar alarm;

Medical Devices human voice prompt , treatment instrument;

Home appliances (cooker, rice cookers, microwave ovens);

entertainment devices (game consoles, amusement machine);

Learning Model (Early education machine, children's audio books);

Intelligent Transport Equipment (toll stations, car parks);

communications equipment (telephone switches, telephones);

Industrial control areas (elevators, industrial equipment);

Advanced toys.

最好选择双头或三头甚至四头的旋转式剃须刀。对于过敏性肤质的男士来说,选择剃须刀也跟女人选择化妆品一样谨慎。业内人士表示,镍是最为常见的过敏原,在皮肤破损时,细菌的感染、过多的摩擦都可以增加镍的吸收,因此,有些电动剃须刀的电震颤虽然可起到震颤按摩、疏通经络气血、增强口唇周围和面颊区域活力的作用,但是少数男士使用后,口旁的皮肤会痒上一阵子,这可能与接触电动剃须刀中所含的镍有关。
