iFlytek XFS3031CN Chinese Voice Synthesis Chip Datasheet
The XFS3031CN is a Chinese voice synthesis chip from iFlytek Digital Technology Co., Ltd. It receives text via a UART interface and outputs synthesized speech. The chip supports multiple character encodings (GB2312, GBK, BIG5, Unicode) and offers various control commands such as synthesize, stop, pause, resume, and power‑down.
The datasheet provides detailed pin definitions, packaging information (LQFP64, 10 mm × 10 mm × 1.4 mm), electrical characteristics, and a list of built‑in sound and chord prompts. It also describes hardware and software methods for querying chip status and outlines ordering information. This manual is written in Chinese.
