The N572F065 is the first Cortex™-M0 based processor for voice process applications, running up to 48 MHz and equipped with 64 KB flash and 8 KB 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. An USB device and flash work together to provide updatable content and scenario downloaded from internet via a PC.

To utilize the high performance M0 and high density of SRAM , advanced algorithms are designed, optimized, and tested in N572F065 chip. These algorithms include watermark, voice changer, NuSound, NuOne, beat detection, and more in developing. In addition to algorithms developed by ourselves, Nuvoton also seeks third parties for more interesting software to enrich the applications on N572F065. Additionally, the new designed NVIC in M0, the latency of interrupt and response to external events are faster. Multiple algorithms could be run together smoothly and naturally.

The development tools are based on Keil™ MDK using C/C++ for programming language. This is a robust and easy to use environment for development and debug.
