N572F072/P072 Data Sheet
1. General Description
The N572F072 is the enhanced NuVoiceseries from N572F065. NuVoice is the first SoC specific for voice
applications based on Cortex-M0 CPU. It runs up to 48MHz and equips with 72KB flash and 8KB SRAM for high
performance process of audio and voice algorithms. Integrating rich analog peripherals, like pre-amplifier, ADC,
DAC, hardware mixer, and PA, this chip saves a lot of system design effort and cost.
To unfold the high performance M0 and high density of SRAM, advanced algorithms are designed, optimized,
and tested with N572 chips. These algorithms include voice changer, low-bit rate compression NuOne;
NuSound; NuLite; NuVox, beat detection, pitch in and pitch out, talk2sing, and more in developing. In additional to
algorithms developed by Nuvoton, we also seek third parties for more interesting features/software to enrich the
applications on N572.
With the NVIC in M0, the latency of interrupt and response time to external events is very short and efficient.
Multiple algorithms can be run together smoothly and naturally.
The development tools are based on KeilMDK using C/C++ programming language. This is a robust and
easy to use environment for software development and debug. Features in KeilMDK are compiler, debugger,
and profiler. With the Nu-Linkand evaluation board, the overall system, including HW and SW, can work
seamlessly in your system testing and verification. In this full-features development environment and tools, you
can design and build application software in an efficient way and get optimized code that can best realize your idea
on N572.
