The NYQUEST NY3W Series (OTP) speech synthesizer datasheet provides specifications, features, pin descriptions, and application information for the…
The NY3W Series is a single‑chip CMOS speech synthesizer with an embedded OTP EPROM. It offers three configurable I/O pins (OKY/O3, IO1, IO2) and a single Power PWM output that can directly drive speakers from 4 Ω to 64 Ω. The device supports wide operating voltages (1.6 V – 6.8 V) and includes a range of special functions such as mode switching, power‑on play, debounce options, and internal feedback.
Development tools like Q‑Speech and Quick‑IO simplify programming, while the datasheet details electrical characteristics, pin assignments, maximum ratings, and example application circuits for easy integration into consumer and industrial products.
