STM32L412KB Ultra-low-power FPU Arm Cortex-M4 MCU 80 MHz 128 Kbytes memory

The STM32L412xx devices are ultra-low-power microcontrollers based on the high-performance Arm^® Cortex^®-M4 32-bit RISC core operating at a frequency of up to 80 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision that 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.
