Description

The STM32L552xx devices are an ultra-low-power microcontrollers family (STM32L5 Series) based on the high-performance Arm® Cortex®-M33 32-bit RISC core. They operate at a frequency of up to 110 MHz. The Cortex®-M33 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®-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. These devices embed high-speed memories (512 Kbytes of Flash memory and 256 Kbytes of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), an Octo-SPI Flash memories interface (available on all packages) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. The STM32L5 Series devices offer security foundation compliant with the trusted based security architecture (TBSA) requirements from Arm. They embed the necessary security features to implement a secure boot, secure data storage, secure firmware installation and secure firmware upgrade. Flexible life cycle is managed thanks to multiple levels of readout protection. Firmware hardware isolation is supported thanks to securable peripherals, memories and I/Os, and also to the possibility to configure the peripherals and memories as “privilege”. The STM32L552xx devices embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, secure and hidden protection areas.
