GENERAL DESCRIPTION

The NuMicro

NUC505 series 32-bit microcontrollers are embedded with ARM

Cortex

® -M4F

core for consumer and industrial applications which need high computing power and rich

communication interfaces.

The ARM

® Cortex® -M4F core within NuMicro® NUC505 series can run up to 100 MHz and support

DSP extensions and Floating Point Unit (FPU) function. The NuMicro

® NUC505 series supports

128 Kbytes embedded SRAM with zero-wait state and 512 KB/ 2 Mbytes embedded SPI Flash

memory, and is equipped with plenty of high performance peripheral devices, such as 24-bit

Audio CODEC, USB2.0 High-speed Device, USB2.0 Full-speed Host, and other peripheral.

The NuMicro

® NUC505 series is suitable for a wide range of applications such as:



Audio and Wireless Audio Applications
