WTV series voice chips are a series of voice chips launched by Shenzhen Weichuang Zhiyin Electronics Co., Ltd. Their superior performance and affordable prices can provide users with higher cost performance. This series of chips includes WTV010, WTV020, WTV040, WTV080, WTV170, WTV340 and other voice chips. In terms of functions, WTV010, WTV020 and WTV040 have the same functions as WTV040, WTV080, WTV170, WTV340 and other voice chips. This instruction only introduces the relevant information of WTV040, WTV080, WTV170, WTV340 and other voice chips.
And Voice programming software for WTV series voice chips The operation interface is simple, easy to operate, and has complete functions. Making full use of the internal resources of the chip can greatly shorten the production cycle of the chip.
This chip has many unit circuits, and has strong programmable ability. In addition to playing voice, it can also play MIDI music can not only realize standard control mode, but also customize various functions according to requirements, so as to improve the cost performance of the product as much as possible. It can also control various electrical equipment, and can be used in many fields, such as electronic piano, toys, children's learning machines, anti-theft equipment, smart home appliances, health care and physiotherapy products, instruments, and various automatic control systems.
In many products that require high sound quality and flexible functions, WTV series voice chip is one of the cost-effective solutions, and it is also a better choice to replace ISD series voice chip in some occasions!
Function description:
☆ Programmable OTP voice chip.
☆ At 6KHZ frequency, the voice length can reach 10 seconds, 20 seconds, 40 seconds, 80 seconds, 170 seconds and 340 seconds respectively according to the chip model.
☆ Built in 16bits DAC digital/analog converter, PSG voice synthesizer and sound quality optimization algorithm, which can show relatively high quality audio.
☆ PWM and DAC are two audio output modes.
☆ Mute can be inserted arbitrarily without occupying speech space.
☆ The same voice can be called repeatedly and does not occupy voice space.
☆ Multiple working modes: key control mode, key combination control mode, parallel port control mode, serial port control mode, etc.
☆ When playing voice, the BUSY pin can set the output high level or low level as required.
☆ Built in 0.5W speaker direct drive, no additional components are required, the sound quality and volume are better than the traditional 'Cout+triode', and the power consumption is less.
☆ Working voltage range: 2.5V to 3.6V.
☆ The power consumption is 2uA in the power-saving mode. In the power-saving mode, the chip will automatically sleep 1 second after power on or 1 second after voice stop playing.
☆ DIP16, SOP16, SSOP20, QFP44 and other packaging forms are available.
☆ Powerful programmable ability, can customize various complicated functions according to needs.
Application examples
In terms of chip application, it can almost involve low cost without changing the voice location, such as :
