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.\u003c\/p\u003e\u003cp\u003eTo 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.\u003c\/p\u003e\u003cp\u003eWith 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.\u003c\/p\u003e\u003cp\u003eThe development tools are based on Keil\u003csup\u003e™\u003c\/sup\u003e MDK using C\/C++ programming language. This is a robust and easy to use environment for software development and debug. Features in Keil\u003csup\u003e™\u003c\/sup\u003e MDK are compiler, debugger, and profiler. With the Nu-Link\u003csup\u003e™\u003c\/sup\u003e and 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.\u003c\/p\u003e\u003ch5\u003eTechnical Documents\u003c\/h5\u003e\u003cul\u003e\u003cli\u003eFor more details, please visit Nuvoton Official Website: \u003ca href=\"http:\/\/www.nuvoton.com\/hq\/products\/application-specific-socs\/arm-based-audio\/nuvoice-series\/n572f072?__locale=en\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eGO\u003c\/a\u003e\n\u003c\/li\u003e\u003c\/ul\u003e","brand":"Nuvoton Direct","offers":[{"title":"Tray","offer_id":43529067987150,"sku":"N572F072G","price":1.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/0749\/7934\/files\/466.jpg?v=1779170351"},{"product_id":"nsp-1-wtr","title":"NSP-1-WTR","description":"\u003cp\u003eThe NSP-1-WTR is a full-functional debugger and programmer with debugging and online\/offline programming.
