STM32L552 and STM32L562 microcontrollers extend the STM32 ultra‐low‐power portfolio and performance with an Arm® Cortex®‐M33 processor core with TrustZone® for Armv8-M, DSP and floating‐point unit (FPU) at 110 MHz.
- The STM32L552 portfolio offers from 256 to 512 Kbytes of Flash memory and from 48 to 144-pin packages.
- The STM32L562 is available with 512 Kbytes of Flash memory and provides an additional encryption accelerator engine (AES, PKA, and OTFDEC).
All the packages are available with or without an embedded SMPS (DC/DC buck voltage regulator). Please refer to the data brief.
The STM32Cube.AI is an extension pack of the widely used STM32CubeMX configuration and code generation tool enabling AI on STM32 Arm® Cortex®-M-based microcontrollers.
Security has emerged as one of the 3 key areas that developers of embedded and IoT applications are thriving to improve. The STM32L5 microcontroller series is the solution and provide a new optimal balance between performance, power and security. The STM32L5 MCU series harnesses the security features of the Arm Cortex-M33 processor and its TrustZone for Armv8-M combined with ST security implementation. ST-proprietary ultra-low-power technologies create a class-leading MCU for energy-conscious applications such as Internet of things (IoT), medical, industrial and consumer. Offering up to 512 Kbytes of flash (dual bank) memory and 256 Kbytes of SRAM, the STM32L5 series of microcontrollers reaches an upgraded level of performance (427 CoreMark) thanks to this new core and a new ST ART Accelerator™ (supporting now also external memory). The STM32L5 offers a large portfolio with 7 packages (from 48 to 144 pins) and supports up to 125°C ambient temperature.
