STM32 ultra low power MCUs

This STM32U3 series offers best-in-class low-power consumption, based on Arm® Cortex®-M33 core. It is the first STM32 based on near-threshold technology, reducing the dynamic consumption drastically. It enables robust security to safeguard sensitive and mission-critical applications, with two new security mechanisms.

The STM32U5 series offers advanced power-saving microcontrollers, based on Arm® Cortex®-M33 to meet the most demanding performance requirements. The series also adds the state-of-the-art features which are required in today’s applications, including advanced cyber security with hardware-based protection, and graphics accelerators for rich graphical user interfaces.

The STM32L5 series enhanced security features leverage the Arm® Cortex®-M33 and its TrustZone® for Armv8-M. Thanks to this new core and the new ST ART Accelerator™ (which also supports external memory), the STM32L5 reaches 443 CoreMark.

The STM32L4 series, based on Arm® Cortex®-M4, offers the excellence of ST’s ultra-low power platform with an additional performance dimension by providing 100 DMIPS with DSP instructions and Floating-Point Unit (FPU), more memory (up to 1 Mbyte of flash memory), and innovative features.

The STM32L4+ series, based on Arm® Cortex®-M4 , extends STM32L4 technology by offering higher performance (120 MHz/409 CoreMark executing from internal flash memory), larger embedded memories (up to 2 Mbytes of flash memory and 640 Kbytes of SRAM), and rendering advanced graphics without compromising ultra-low-power consumption.

The latest generation of entry-level, ultra-low-power MCUs, the STM32U0 series based on Arm® Cortex®-M0+, offers an ideal combination of energy consumption, features, and cost for entry-level applications. This series has been labeled "Sustainable Technology" as it contributes to reducing the carbon footprint by minimizing power consumption in end devices, thus helping to decrease their environmental impact.

The STM32L0 series, based on Arm® Cortex®-M0+, offers a genuine energy-saving solution for entry-level applications. Available in tiny packages down to 14 pins and with a wide range of flash memory densities from 8 to 192 Kbytes, the STM32L0 features ultra-low power consumption in a competitive portfolio.
