It has all the functionalityof VS1053 (except MP1 and MIDIdecoding) and many new features, particularlyMP3 and Ogg Vorbis recording.Also full-duplex codec functions for phone applicationshave been added to VS1063a.A factory-programmable unique chip ID providesa basis for digital rights management orunit identification features.Operating ModesVS1063a operates in one of two host modes:as a slave co-processor or as a standaloneprocessor.When used as a slave co-processor VS1063acan operate in three different operation modes:decoder, encoder or codec mode. In decodermode VS1063a receives its input bitstreamthrough a serial input bus. The input streamis decoded and passed through an 18-bit digitalvolume control to an oversampling sigmadeltaDAC. Decoding is controlled via a serialcontrol bus. In addition to the basic decoding,it is possible to add application specificfeatures, like DSP effects, to the user RAMmemory, or even to load user applications.In encoder mode VS1063a can reads audiofrom its analog inputs, optionally compressesthe data, which can then be read by the hostprocessor. In codec mode VS1063a offers afull-duplex audio interface.When used as a standalone processor theVS1063a can boot either from SPI EEPROMor FLASH memory. Alternatively code anddata can be provided by a host controller.User CodeUsers can write their own user interface orsignal processing code for the VS1063a usingVSIDE (VLSI Solution’s Integrated DevelopmentEnvironment).As a default, there are 16 KiB of free codeRAM and about 4 KiB of free data RAM foruser applications. Depending on the application,the data RAM can be expanded to thefull 80 KiB that is available in VS1063a.Version: 1.02, 2012-12-05 2
