The decoding is con-trolled via a serial control bus. In addition to basicdecoding, it is possible to add application specificfeatures, like DSP effects, to the user RAM mem-ory.Version 1.04, 2007-10-08 1VLSISolutionyVS1011eVS1011ECONTENTSContents1 License 82 Disclaimer 83 Definitions 84 Characteristics & Specifications 94.1 Absolute Maximum Ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 94.2 Recommended Operating Conditions . . . . . . . . . . . . . . . . . . . . . . . . . . . . 94.3 Analog Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 104.4 Power Consumption . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 104.5 Digital Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 114.6 Switching Characteristics - Boot Initialization . . . . . . . . . . . . . . . . . . . . . . . 115 Packages and Pin Descriptions 125.1 Packages . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 125.1.1 LQFP-48 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 125.1.2 BGA-49 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 135.1.3 SOIC-28 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 135.2 Pin Descriptions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 145.2.1 LQFP-48 and BGA-49 Pin Descriptions . . . . . . . . . . . . . . . . . . . . . . 145.2.2 SOIC-28 Pin Descriptions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 156 Connection Diagram, LQFP-48 167 SPI Buses 17Version 1.04, 2007-10-08 2VLSISolutionyVS1011eVS1011ECONTENTS7.1 General . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 177.2 SPI Bus Pin Descriptions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 177.2.1 VS1002 Native Modes (New Mode) . . . . . . . . . . . . . . . . . . . . . . . . 177.2.2 VS1001 Compatibility Mode . . . . . . . . . . . . . . . . . . . . . . . . . . . . 177.3 Serial Protocol for Serial Data Interface (SDI) . . . . . . . . . . . . . . . . . . . . . . . 187.3.1 General . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 187.3.2 SDI in VS1002 Native Modes (New Mode) . . . . . . . . . . . . . . . . . . . . 187.3.3 SDI in VS1001 Compatibility Mode . . . . . . . . . . . . . . . . . . . . . . . . 187.4 Data Request Pin DREQ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 197.5 Serial Protocol for Serial Command Interface (SCI) . . . . . . . . . . . . . . . . . . . . 197.5.1 General . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 197.5.2 SCI Read . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 217.5.3 SCI Write . . . . . . . . . . . . . . . . . …
