Our company develops a multimedia codec chip that integrates an internal 0.5W digital power amplifer. The internalintegrated data storage space can store the sounds that need to be played into the voice chip or external memory. TheMCU commands /lC/UART/ through the l0 port, and can also it is played through the serial port data stream to thechip. lt has simple control and supports MP3 audio format with high compression rate. lt can also support PCM formatit also supports MlC pickup and converts it into a standard MP3 format digital signal and sends it through the serialport and uploads it to other devices. Currently, there is WT2003H , WT2605, and WT2605C three series; different chipscorrespond to diferent application scenarios, which can well meet customers’ product needs, Our company’s conceDiof making complexity simple allows customers to quickly get started using our multimedia codec chips.

WT2003H Series
WT2605 Series
The WT2003H series of MP3 chips play an important role in Waytronic products. The WT2003H series uses a high-performance 32-bit processor with a maximum frequency of 120MHz. It has the characteristics of low cost, low power consumption, high reliability, and strong versatility.
The control method is flexible: Support standard serial communication (UART), with file index playback, inter-play, single cycle, all track cycle, 32-level volume adjustment, random playback, etc.
If you need to use a TF card as storage, you can choose WT2003H4-16S TF card version, if the memory is SPI flash, you can refer to the FLASH version of WT2003H4-16S, which can support external 128Mbit Flash.
Of course, they can also exist at the same time. In addition, the powerful WT2003HP8-32N has 8M bit built-in Flash, super small package size, is the best choice for high-end audio products.
In addition, the WT2605 series also supports MP3 decoding, not only playback but also MP3 recording, Bluetooth audio broadcast, and other functions. You can refer to the WT2605B03 module program.
