The NUC500 series features high performance, low cost and low power 32-bit ARM® ARM7TDMI core and embedded 32 KB/64 KB SRAM, and runs up to 80 MHz to support 2.4GRF wireless speaker. The NUC500 series provides high MIPS support better performance audio compress/decompress algorithm and audio codec, two sets of UARTs and USB device. All the functions for the 2.4GRF wireless microphone are integrated in one chip to save BOM cost and facilitate data update though PC. Based on the above features, the NUC500 series is a cost-effective solution for 2.4GRF wireless microphone applications. In addition, the NUC500 can be used for a 2.4GRF demo system. This demo shows high audio quality, stability and better distance than other solutions.
