NVC series voice chip is the latest introduction of Guangzhou nine core electronic technology is suitable for factory production typeIndustrial gradeOTP voice chip. It has the advantages of low cost, stable performance, high quality, convenient control, simple circuit, and so on. NVC series voice chip introduced to approimate the price in the current industry mask, but no minimum limit, make up the industry a problem, suitable for low cost and fast production, the fastest only shipments a day can be.

NVC is a stable performance of the voice chip, without any eternal circuit, under etremely harsh noise environment can work normally. It has a wide range of temperature and pressure resistance range, the normal work of a wide range of 1.8V~5.5V, make up the defects of poor anti-interference ability of voice chips in the market at present.

NVC series of voice chip has a group of PWM output port, you can push 0.5W speaker, the sound quality is clear. Built in LVR reset, no eternal reset circuit. The built-in resistance frequency vibrator accurate (maimum error of only +-1%), without eternal resistance. NVC is a very obvious advantage is OTP burning program can mask mask seamless, that is to say, the pre trial production phase, the user can OTP trial production, after a successful pilot into mass production can be directly according to the OTP samples production mask mask to reduce costs, customers do not need to confirm the second sample.

NVC series of voice chips with a variety of key trigger mode, and can be output in a variety of forms of level signals, can be set according to the rhythm of the rhythm of speech. In addition to NVC support the main control MCU first-line serial control, can be arbitrarily controlled multi voice trigger, is the only 8 foot chip on the market to support the 220 segment of the voice of the voice chip.

NVC series voice chip support DAC eternal power amplifier, support for playing the sound of a beautiful chord MIDI music.

NVC series voice chip has a variety of practical forms of encapsulation: DIP8, sop8, cob etc., peripheral circuit only a power coupling capacitors can be, work stability, wide working voltage, ultra low standby power consumption and a wide resistance temperature properties of the NVC series voice chips have first-class price advantage in a wide range of applications.
