XF-S3011 Chinese TTS chip datasheet, which provides detailed information about the chip's features, functions, peripheral circuits, package form, and electrical characteristics.
The XF‑S3011 is a Chinese voice synthesis chip developed by iFlytek. It integrates a complete TTS system into a single processor and can synthesize arbitrary Chinese text received via a UART interface. The chip is offered in a 44‑pin QFP package and is suitable for embedded devices that require Chinese speech output.
Key features include support for GB2312 and Unicode text encodings, built‑in music and prompt sounds, text‑analysis algorithms for numbers, dates, and names, UART communication at 9600 bps, dual 10‑bit DAC audio outputs, and low‑power sleep mode. Electrical specifications such as supply voltage (2.6‑5.5 V), operating temperature (‑40 °C to +85 °C), and current limits are detailed in the sheet. This manual is written in Chinese.
