1-Channel Speech Synthesizer
The NY3P (=VLN3P) series are single-chip voice synthesizing CMOS IC. According to different IC series, each body has one to five I/O pins. Through accurate internal oscillation, external Rosc is unnecessary. There is only one PWM output for voice. Thus any external component is not required. Customer’s speech data can be programmed into ROM by changing one code mask during fabrication.
Feature
- Wide operating voltage: 1.6V ~ 6.4V.
- Total maximum 1536 Voice Steps are available for 128 Voice Sentences.
- 10-bit PWM output. It can directly drive 8, 16, 32, 64Ω speaker or piezo-buzzer.
- Low-Voltage-Reset (LVR) option.
When voltage is lower than 1.5V, IC will reset by itself. (Mask Option) - Only build in an accurate internal oscillator, no external R oscillator.
There are many kinds of options for play speed, and each Step can select any one of them independently.
OKY1 (E/U/R) =S1 S2 S3 S4, IO1 (E/U/R) =S5 (OKY1 Reset is enabled, and S5 is a short mute Sentence)
※ The pulse width must be longer than 50us (i.e. short debounce time), and users can set the typical pulse width as 100us.
※ The above is the simplest 2-wire control by external MCU. If necessary, user can use 3-wire control with Busy_High output signal to do feedback.
