STM32L552CCU6

STM32L552CCU6 is an ultra-low-power microcontroller based on the high-performance Arm® Cortex®-M33 32bit RISC core. It operates at a frequency of upto 110MHz. It 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®-M33 core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security. This device offers a security foundation compliant with the trusted-based security architecture (TBSA) requirements from Arm. It embeds the necessary security features to implement a secure boot, secure data storage, secure firmware installation, and secure firmware upgrade. A flexible life cycle is managed thanks to multiple levels of readout protection.
