Description

VS1063a is an easy-to-use, versatile encoder,

decoder and codec for a multitude of audio

formats.

VS1063a contains a high-performance, proprietary

low-power DSP core VS_DSP4, ROM

memories, 16 KiB instruction RAM and up to

80 KiB data RAM for user applications running

simultaneously with any built-in decoder,

serial control and input data interfaces, up to

12 general purpose I/O pins, a UART, as well

as a high-quality stereo ADC, and a variablesample-

rate stereo DAC, followed by an earphone

amplifier and a common voltage buffer.

VS1063a can act both as an “MP3 decoder

IC” or “MP3 encoder IC” slave in a system

with a microcontroller, or as a stand-alone circuit

that boots from external SPI memory.
