DSPB56720AG

The DSPB56720AG is a 24-bit dual-core symphony Digital Signal Processor supports multiple high-definition (HD) audio standards. The Symphony™ audio DSP56720 represents the first in a complete family of multi-core 24-bit processors from NXP, further broadening the company's expansive audio portfolio. The DSP56720 retains code compatibility with popular DSP56000 and DSP56300 core families of DSPs while enhancing its capabilities with many new features such as integrated S/PDIF module, an external memory controller, an embedded asynchronous sample rate converter and more audio channels. The Symphony audio DSP56720 excels at audio processing for consumer and professional audio applications requiring high million instructions per second (MIPS). For consumer applications, higher MIPS and memory requirements are driven by the new HD audio standards (Dolby® Digital Plus, Dolby® TrueHD, DTS-HD).

• Asynchronous sample rate converter (ASRC) to allow multiple data rates in a system
• Integrated S/PDIF transceiver to reduce complexity
• Enhanced serial audio interface (ESAI) - 4 modules to allow multiple sources
• Dual serial host interfaces (SHI)
• Support SPI or I²C protocols
• Provides high speed communication between multiple the DSP
• Dual triple timer modules for a flexible, programmable timer system
• Dual hardware watchdog timers (WDT) to allow for recovery from runaway code
