NY2 series products are single-chip CMOS music and speech synthesis ICs. According to different series, it has 1 Input pin and 5 I/O pins. It utilizes precise internal resistance to oscillate, so no external oscillating resistor is needed. A set of PWM output is built in, so no additional parts are needed. The music synthesis method is programmable square wave and envelope, and the speech synthesis method is 4-bit Advanced LOG-PCM. By changing the Code mask during the manufacturing process, different music voice data can be written into ROM. Users can use the simple Q-Tone, Q-Melody and Quick-IO tool software to quickly develop.
characteristic:

    Wide operating voltage: 1.8V ~ 5.5V.
    Music and voice can be divided into up to 128 voice music segments at most.
    Voice and music cannot be output at the same time. You can only choose to output one channel of voice or two channels of music, but you can fill in the voice segment and music segment in the voice music box in the voice music group to achieve the interval between music notes Insert voice.
    There are 25 types of Tempo that can support music. An envelope is applied to the beat length after synthesis, and the beat length in the synthesis can be specified with the same or different pitch and output.
    All output pins can provide high current output to directly push high-brightness LEDs. (Iol=20mA @VDD=3V)
    Each output pin can be set to "Constant Sink Current" (Constant Sink Current, CSC) to limit the current output at 4.5V.
    One set of PWM output, there are two kinds of PWM volume to choose from (normal volume & high volume), which can directly drive 8Ω, 16Ω, 32Ω, 64Ω speakers or buzzers.
    Low voltage reset (LVR) option, when the voltage drops below 1.8V momentarily, the IC will automatically reset. (Mask selection)
