Introduction of common NVB voice chip

News by ninechip | On 2018-07-11 09:05

Voice chips are widely used in life. Let's take a look at the kinetic energy of commonly used NVB voice chips.

NVB: ordinary

It supports main MCU second line serial port control, and can control multi segment voice triggering freely. It is the only 256 chip voice chip on the market that supports 256 segments of voice.

OTP storage format, the production cycle is fast, the fastest time, only one day, there is no minimum limit; flexible multiple key operation mode and level output mode for selection (edge key trigger, level trigger, random key play, sequence key play);

Simple and convenient two line MCU serial port control mode. The user master MCU can control the trigger and stop of any segment voice.

Support 4 keys to trigger.

The voice is 20 seconds, 40 seconds, 65 seconds, 80 seconds, 115 seconds; the built-in PWM output device can push the 0.5W horn directly; the flexible voice operation can save the voice space by combination, and the single data port can play 128 voice combinations at most; the sound quality is beautiful, the performance is stable and the price is cheap;

Built in LVR self-reset circuit to ensure the chip works properly; DIP8, SOP8 and COB three packages are available, easy to use and flexible to use.

The peripheral circuit is simple, only a coupling capacitance is needed.

Working voltage range: 1.8V ~ 4.5V (5V power supply, VDD needs series capacitor voltage drop).

Static current: 2uA;
