STM32L0 series of ultra-low-power MCUs
The STM32L0 series is ST’s entry-level range of 32-bit ultra-low-power MCUs designed to achieve an outstandingly low power consumption level. The result is a genuine ultra-low-power MCU with the world’s lowest power consumption at 125 °C.
The exclusive combination of an Arm® Cortex®-M0+ core and STM32 ultra-low-power features, makes the STM32L0 the best fit for applications operating on batteries or supplied by energy harvesting.
To provide the best power efficiency, the STM32L0 offers dynamic voltage scaling, an ultra-low-power clock oscillator and short wakeup time. New autonomous peripherals (including USART, I²C, and touch sense controller) reduce the load of the Arm® Cortex®-M0+ core leading to fewer CPU wakeups and contribute to decreased processing time and power consumption.
To reduce total application BOM cost, the STM32L0 integrates low-power comparators, embedded EEPROM, and a crystal-less USB interface.
Other value-added features such as 16-bit ADC (hardware oversampling), dual-channel DAC, hardware encryption, and communication peripherals capable of operating in ultra-low-power mode make up for an unrivaled tradeoff between feature integration, performance and ultra-low-energy consumption.
STM32L0 MCUs are available with up to 192 Kbytes of Flash memory, 20 Kbytes of RAM and up to 6 Kbytes of embedded true EEPROM (no emulation needed) in 14- to 100-pin packages, including space-saving WLCSP packages.
STM32L0 MCUs have scored 161 in the standardized EEMBC™ ULPBench® tests that compare the efficiency of ultra-low-power microcontrollers.
Current consumption reference values:
- Dynamic run mode: down to 49 µA/MHz (with external DC/DC) and 76 MHz (with LDO)
- Ultra-low-power mode + full RAM + low power timer: 340 nA (16 wakeup lines)
- Ultra-low-power mode + backup register: 230 nA (2 wakeup pins)
- Wake-up time: 3.5 µs
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
MadeForSTM32™ is a new quality label delivered by ST, which is granted after an evaluation process. It helps engineers identify third party solutions with the highest level of integration and quality for the STM32 microcontrollers' ecosystem. MadeForSTM32™ is offered to members of the ST Partner Program who want to go one step further in our collaboration, with the overall objective of contributing to a high-quality STM32 ecosystem.
