New enhanced N572 Cortex-M0 based processor from Nuvoton for voice apps

Following the success of its first M0-based NuVoice, Nuvoton Technology Corporation has introduced the second NuVoice—N572F072. The N572F072 is the enhanced N572 series from N572F064/F065, the first Cortex-M0 based processor for voice applications. It runs up to 48MHz and equipped with 72KB flash and 8KB SRAM for high performance processing of audio and voice algorithms. Integrates analog peripherals, like pre-amplifier, ADC, DAC, hardware mixer, and PA to save cost and time. Nuvoton also seek third parties for more interesting software to enrich the applications on N572.

Nuvoton says with the NVIC in M0, the latency of interrupt and response time to external events is very short and predictable and multiple algorithms can be run together smoothly and naturally.

The development tools are based on Keil MDK using C/C++ prog.

The new algorithms included in this chip include voice changer, low-bit rate compression, beat detection and pitch shift.
