STMicroelectronics Mikrokontrolér 32 bit ARM Cortex M4 120 MHz 1.024MB Blesk 640 kB RAM, počet kolíků: 144 kolíkový,

The STMicroelectronics STM32 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 Cortex-M4 core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security.
