Jia Taimu's latest multi-functional intelligent voice chip -.. NV series NV is a powerful one-time programmable voice chip, the audio output is PWM or DAC mode selectable control modes key control mode, parallel control Mode, serial control mode triggered flexible way key control mode; in serial mode can control the volume, turn on or off the amplifier with loop and stop function.
jtm-chip 16-bit DA audio output, and comes with an internal filter amplifier, can directly drive 0.5W speakers, built-in programmable PSG speech synthesis technology, truly high-quality and low-noise characteristics; built-in two-channel stereo, You can easily mix playback.
This chip has a number of unit circuit; and there is a strong programmability; addition to being able to play the voice; but also can play high-quality MIDI keyboard music, not only to achieve a standard of control, or according to demand, build all kinds function, as far as possible to make cost-effective products to the highest can control a variety of electrical equipment, etc., can be applied in many fields, such as: Keyboard, advanced toys, children's learning machine, automobile anti-theft devices, intelligent home appliances, health care and physical therapy products , instruments, and a variety of automatic control systems, etc., currently in these areas has been widely used.
