Nuvoton’s ARM® Cortex-M0 based Audio MCU's  provides powerful yet cost effective single-chip solution for applications that require voice/audio features. The highly integrated architecture – 32bit Cortex-M0 processor, microphone interface, 2.4 to 5.5V wide operating voltage, I²S digital audio interface, 1 watt speaker driver, 145KB built-in flash memory, 3V regulator and multi-functions GPIOs was designed to provide cost effective voice/audio solution for consumer and industrial markets.

These system-on-a-chip (SOC) devices, enable designers to develop systems and individual products capable of delivering clear, reliable, easily managed audio recording and playback, system control, that simplifies products’ design time and reduces bill-of-materials costs; the chip’s highly integrated architecture eliminates the need for various periphery chips such as USB, audio Codec.

The ARM® Cortex-M0 in the Nuvoton’s AUI enabler delivers 32-bit performance and low power consumption, but at a price point of an 8-bit microcontroller.  Its 32-bit architecture enables designers to develop complicated algorithms such as voice recognition, text to speech and capacitive touch – applications that at one time required DSPs and/or other high-end, ARM-based devices.
