W588D series voice chip is a programmable voice chip that integrates MCU and voice circuit developed by Taiwan Huabang Technology. It supports 6K～20K sampling rate audio loading, and the unique feature of the chip is to show the loaded audio quality almost perfectly.
This manual introduces the Winbond W588D voice microcontroller series, describing its integrated MCU and voice circuit, supported control modes (MP3, key, matrix, parallel, one‑wire, three‑wire, etc.) and the ability to load up to 500 voice segments. It also explains how to use the optional SPI‑Flash memory for online or offline voice data download.
Detailed sections cover package options (16‑pin, 28‑pin, DIP18, SSOP20, LQFP32), pin‑out tables, electrical parameters, timing diagrams, example application circuits, and a parts list for various package types. The document ends with version history and ordering information. This manual is written in Chinese.
