STM32L552ZET6 Description

The STM32L552xx devices are a family of ultra-low-power microcontrollers (STM32L5 Series) built around the powerful 32-bit RISC Arm? Cortex?-M33 core. They function at frequencies as high as 110 MHz. A single-precision floating-point unit (FPU) that supports all Arm? single-precision data-processing instructions and all data types is a characteristic of the Cortex?-M33 core. A memory protection unit (MPU) and a full set of DSP (digital signal processing) instructions are also implemented by the Cortex?-M33 core, which increases the security of the program.
