Waytronic WT2000T-32N MP3 Audio sound Playback Voice Chip

Product Introduction

The WT2000T series is a range of powerful high-quality voice chip that utilize high-performance 32-bit processors with a maximum frequency of 160MHz. They feature low cost, low power consumption, high reliability, and strong versatility. Currently available is the WT2000T-32N QFN32 package chip, which has a compact size of 4x4mm. It includes functions such as address playback, insert playback, single track loop, all tracks loop, and random playback. The volume can be adjusted in 32 levels, and it supports up to 128Mbit external Flash memory.

Product features

Operating voltage: 2.6-5.2V
MP3 control: Standard UART communication interface, default baud rate of 115200, supports setting baud rate via serial commands; supports SPI-Flash, TF card, USB drive as storage media. Features file index playback, insert play, single track loop, all tracks loop, random play functions. Volume adjustable from 0 to 31 levels, maximum support for external 128Mbit Flash, 32GB TF card, and 32GB USB drive (TF and USB drive support FAT or FAT32 formats)
Upon power-up, playback does not start by default; has a BUSY status indicator, default low level when BUSY during playback, high level when not playing (code can modify default configuration);
Audio output method, sample defaults to DAC output, non-modifiable, hardware supports 24-bit DAC output;
Supports high-quality audio formats for voice, (supports sampling rates from 8K to 44.1K, bitrates from 8kbps to 320kbps) with beautiful sound quality, .MP3, .WAV formats;
Supports random playback, seamless loop playback functions, etc.;
Maximum support for 128Mbit Flash;
Volume adjustable, 32 volume levels;
High-power IO driving capability, up to 30mA direct drive;
Connects to a computer via USB interface, displays Flash or TF card drive letter on the computer, directly copy audio to the drive letter from the computer, after copying is complete, the USB cable must be removed before performing serial port control playback, otherwise serial port code will have no response;
Single-chip usage (using internal capacity) requires pre-written voice at the factory;
Power-on initialization time is 930ms-1.5s, due to PC mode version, needs to mount the file system, initialization time is relatively longer than ordinary voice IC, it is recommended to establish communication connection with the voice IC and send codes after 930ms-1.5s;
Important note: If the voice chip needs to hang flash, it is recommended to use ‘Weitek’ flash, other manufacturers’ flash cannot guarantee normal operation. (It is suggested to mark 150mil and 208mil size compatible extensions for easier inventory).
