M4 Audio Codec Function

The NUC505 Series is a range of 32-bit microcontrollers developed by Nuvoton, featuring the powerful ARM Cortex-M4F core with DSP and FPU capabilities. These microcontrollers operate at a maximum frequency of 100 MHz and are designed for applications such as thermal printers, GPS trackers, 2.4G wireless audio, and other audio-related systems. These microcontrollers offer substantial memory, featuring 128 KB of embedded SRAM and either 512 KB or 2 MB of SPI Flash. They also provide a wide variety of connectivity options, including USB 2.0 HS Device and FS Host capabilities, up to three UARTs, two SPIs, two I²Cs, and an SD Host. With built-in security features, such as 128-bit key code protection and 15-entry allowances, the NUC505 Series ensures that your code is well-protected against unauthorized access. The integrated RTC supports an external power pin (VBAT) and offers 32 bytes of spare register space. The I²S functionality within these microcontrollers supports master or slave mode operation, internal PLL frequency adjustment, and multiple data formats. Additionally, DMA mode is available for optimal efficiency. The 12-bit ADC offers up to eight channels with varying conversion rates, depending on the channel. With an embedded 24-bit Sigma-Delta audio codec, the NUC505 Series delivers exceptional audio quality, featuring a dynamic range of SNR and THDN specifications for both ADC and headphone output. The sample rate ranges from 8 kHz to 96 kHz, catering to different audio applications. These microcontrollers are available in various packages such as LQFP48, QFN48, LQFP64, and QFN88, and have a wide operating temperature range of -40℃ to +85℃, ensuring reliability across various environments.
