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.
