Audio DSP56720 represents the first in a complete family of multi-core 24-bit processor. The DSP56720 retains code compatibility 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 and embedded asynchronous sample rate converter and more audio channels.

The DSP56720 offers a solution with high performance without sacrificing on cost or power consumption and can replace a multi-DSP design with a single chip solution. It provides a wealth of on-chip audio processing functions, via a plug and play software architecture system which has the ability to support audio decoding algorithms as well as various post processing functions.

Features:

• Dual DSP56300 cores for high performance
• 248 K x 24-bit words RAM
• Asynchronous Sample Rate Converter (ASRC) to allow multiple data rates in a system
• Integrated S/PDIF transceiver to reduce system cost and complexity
• External Memory Controller (EMC) provides for memory expansion to cost-effective SDRAM and flexibility in system design by providing memory expansion for one or both cores
• Enhanced Serial Audio Interface (ESAI) – 4 modules to allow multiple sources
• Dual Serial Host Interfaces (SHI) that support SPI or I2C protocols which provides high speed communication between multiple the DSP and other integrated circuits in the system
• Dual Triple Timer modules for a flexible, programmable timer system
• Dual Hardware Watchdog Timers (WDT) to allow for recovery from runaway code
• 144LQFP Package

Applications:

• A/V receivers
• Blu-ray and HD-DVD players
• Professional audio recording systems
