VS1000中文资料Ogg Vorbis Player System Circuit数据手册VLSI规格书

描述 Description

The VS1000 is a system-on-a-chip. Instead of being yet another \"MP3 decoder circuit\" the VS1000 plays back Ogg Vorbis, which is both a technically superior format and free of royalty payments. Because of this the VS1000 IC is a cost-effective and high-quality solution for applications where the actual audio format doesn't make a difference, but quality does - like toys and different audio guides. The chip also has NAND FLASH and Full Speed USB interfaces, plus I/O pins that can be used to control e.g. an LCD or OLED matrix display. It can also regulate its internal voltages from a single input voltage, so connecting it to a system is easy.
