This document is the user manual for WT5801M14 produced by Guangzhou Weichuang Electronics Co., Ltd. It describes the features and characteristics of the product, such as support for different voice storage times, support for different capacity SPI-Flash memory, built-in voice processor, and high-quality voice output support.
The WT5801M14 is a 14‑pin voice module that integrates a WT588D voice chip, supports SPI‑Flash memory from 2 Mbit to 32 Mbit, and offers PWM or DAC audio output. It can store up to 500 voice segments and operates from a 5 V DC supply with a sleep current below 10 µA.
Three control methods are described: button control, one‑wire serial, and three‑wire serial. The manual includes detailed pin assignments, electrical parameters, environmental limits, typical application circuits, and example programs in assembly and C for both serial interfaces. This manual is written in Chinese.
