ARM MCU微控制单元, STM32 Family STM32L4 Series Microcontrollers, ARM 皮质-M4, 32位, 120 MHz, 2 MB, 640 KB

The STM32L4R5xx devices are an ultra-low-power microcontrollers family STM32L4+ Series based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 120 MHz. The Cortex-M4 core features a single-precision floating-point unit FPU, which supports all the Arm® single-precision data-processing instructions and all the data types. The CortexM4 core also implements a full set of DSP digital signal processing instructions and a memory protection unit MPU which enhances the application"s security.
