The STMicroelectronics microcontroller , This devices are based on the high-performance Arm Cortex -M4 32- bit RISC core operating at a frequency of up to 100 MHz. The Cortex-M4 core features a floating-point unit (FPU) single precision, which supports all Arm single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU), which enhances application security.
