Description
General part information
NUCLEO-L552ZE-Q Series
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.
