STM32L4 32-Bit Low-Power Microcontrollers +FPU

STMicroelectronics STM32L4 32-Bit Low-Power Microcontrollers +FPU are ultralow-power MCUs based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80MHz. 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.
