NVD voice chip OTP voice chip sop8 voice chip 170s voice IC

NVD is a voice chip with stable performance. It does not need any peripheral circuit and can work normally in extremely harsh noise environment. It has a wide temperature and voltage resistance range, and the normal working range is 2V ~ 5.5V, which makes up for the poor anti-interference ability of voice chips on the market.

NVD series voice chip has a set of PWM output ports, which can directly push 0.5W horn with clear sound quality. Built in LVR reset without additional reset circuit. Built in accurate internal resistance frequency vibrator (the maximum error is only + - 1%), without external resistance. An obvious advantage of NVD is that the OTP burning program can be seamlessly connected with the mask mask, that is, in the early trial production stage of the product, users can OTP trial production. When entering mass production after the trial production is successful, they can directly put the mask mask into production according to the OTP sample to reduce the cost, and customers do not need to confirm the sample again.

NVD series voice chip has a variety of key trigger modes, and can output various forms of level signals, which can be set to change according to the fluctuation rhythm of voice. In addition, NVD supports one-line serial port control of the main control MCU and can arbitrarily control multi segment voice trigger. It is one of the few 8-pin voice chips that support 223 segments of voice on the market.

NVD series voice chip has a variety of practical packaging forms: sop8, cob, etc. the peripheral circuit only needs a power coupling capacitor. It works stably. Wide working voltage, ultra-low standby power consumption and wide temperature resistance make NVD series voice chip have first-class cost performance advantages in a wide range of application fields.
