STMicroelectronics STM32L4S5VIT6, 32bit ARM Cortex M4 Microcontroller, STM32L4+, 120MHz, 2 MB Flash, 100-Pin LQFP

The STM32L4S5xx, STM32L4S7xx and STM32L4S9xx 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.
