BELASIGNA 250 High-Performance Programmable Audio Processing System Introduction BELASIGNA 250 is a complete programmable audio processing www.onsemi.com system, designed specifically for ultralowpower embedded and portable digital audio systems. This highperformance chip builds on the architecture and design of BELASIGNA 200 to deliver exceptional sound quality along with unmatched flexibility. BELASIGNA 250 incorporates a full audio signal chain, from stereo 16bit A/D converters or digital interfaces to accept the signal, through the fully flexible digital processing architecture, to stereo analog linelevel or direct digital power outputs that can connect LFBGA64 7x7 directly to speakers. CASE 566AF BELASIGNA 250 features flexible clocking options and smart power management features including a soft powerdown mode. Two DSP subsystems operate concurrently: the RCore, which is a fully MARKING DIAGRAM software programmable DSP core, and the weighted overlapadd (WOLA) filterbank coprocessor, which is a dedicated, configurable processor that executes timefrequency domain transforms and other XXXXYZZ vector based computations. A full range of other hardwareassisted BELASIGNA features, such as audiotargeted DMA complete the system. 250 0W888002 A comprehensive and easytouse suite of development tools, AAAA handson training and full technical support are available to enable rapid development and introduction of highly differentiated products 0W888002 = Device Code in record time. XXXX = Date Code Y = Assembly Plant Identifier Key Features ZZ = Traceability Code Unique Parallelprocessing Architecture: A Complete DSPbased, AAAA = Country of Assembly Mixedsignal Audio System Consisting of a 16bit Fully Programmable DualHarvard 16bit DSP Core, a Patented, Highresolution Block Floatingpoint WOLA Filterbank Coprocessor, ORDERING INFORMATION and an Input/Output Processor (IOP) along with Several Peripherals See detailed ordering and shipping information in the package and Interfaces which Optimize the Architecture for Audio Processing dimensions section on page 23 of this data sheet. Integrated Converters and Powered Output: Minimize Need for External Components Ultralow Power Consumption: Under 5 mA at 20 MHz to Support Advanced Operations 1.8 V Supply Voltage Smart Power Management: Including Low Current Standby Mode Requiring Only 0.05 mA Flexible Clocking Architecture: Supports Speeds up to 50 MHz 2 Full Range of Configurable Interfaces: Including: I S, PCM, 2 UART, SPI, I C, TWSS, GPIO Excellent Fidelity: 88 dB System Dynamic Range, Exceptionally Low System Noise and Low Group Delay Support for IP Protection: to Prevent Unauthorized Access to Algorithms and Data These Devices are PbFree, BFR Free and are RoHS Compliant Semiconductor Components Industries, LLC, 2015 1 Publication Order Number: April, 2018 Rev. 11 B250/D
