WT2003H Serial MP3 Chip Specification
■WT2003HX is a powerful and high-quality MP3 chip upgraded from the MP3 chip of WT2003S to meet the market demand. It uses a high-performance 32-bit processor with a maximum frequency of 120MHz. It has the characteristics of low cost, fast response speed, low power consumption, high reliability, strong versatility and so on, and can meet customers'requirements from various aspects. Support standard asynchronous serial communication, flexible control mode. Support SPI-Flash as memory. With file index playback, spot insertion, single loop, all loop, 32-level adjustable volume and stereo output. Mass storage, up to 128M Flash disk. At present, there are three packaged chips, WT2003HX-16S,WT2003HX-24SS and WT2003HP8-32N (4*4MM smaller), which can better adapt to different application product fields.
●Characteristics
■MP3 control: standard UART communication interface, the default baud rate is 9600, which supports setting baud rate through serial port command; Support SPI-Flash, TF card and U disk as memory. With the functions of file index play, spot insertion, single loop, all tracks loop, random play, etc. Level 32 has adjustable volume, and can support 128Mbit Flash, 32G TF card and 32G U disk at the maximum.
