Registered addres:room308,NO.1TIANTAI first street,luogang Guangzhou,Guangdong,China.
Founded in:May 27th,2010
enterprise funcation:corporation limited
Business scope: Electronic components technology research and development, The design of electronic products production and sales, And after sales service.
1. NVB series voice chip is our launched a suitable for factory product,based industrial grade OTP's voice chip.
2. NVB is the voice chip of a stable performance, without any external circuit. It can work normally in extremely harsh noise environments. It has a broadrange of normal temperature and pressure resistance. Wide operating range is 1.8V~4.5V.
3. NVB series voice chips have a set of PWM output port, can direct push 0.5W horn, clear sound quality.
4. NVB series voice chips with multiple keys trigger mode, and can level signal output in various forms, can be changed according to the rhythm of speech set ups and downs.
5. NVB series voice chips with various forms of utility package: DIP8, SOP8,peripheral circuit needs only one power coupling capacitance to be.
Function and characteristics:
1.OTP storage format, production cycle is fast,only the fastest one day, place an order is no minimum limit;
2.Flexible multi key mode of operation and the level of output options (edge trigger button, triggering level,random keys, the keys sequence to play );
3.Simple two lines MCU serial control mode.The user of master MCU can control the touch of arbitraaily segments of speech to play or to stop.
4.The voice cuold play 20 seconds,40 seconds,65 seconds,80 seconds or 115 seconds.
5.Support 4 trigger button.
6.Built in a group of PWM,which output direct push 0.5W horn;
7.Have a good sound,stable performance and high quality and inexpensive.
8.The peripheral circuit is simple, only needs a coupling capacitor.
9.Working voltage range:1.8V ~ 4.5V( 5V power VDD series should connected capacitor step-down if needed )
11. DIP8, SOP8 and COB three kinds of packages are available.It's easy and flexible to use.
