STM32 L0 series of ultra-low-power MCUs
Every part of the STM32 L0 MCUs has been optimized to achieve an outstandingly low power consumption level. The result is a genuine Ultra-Low-Power MCU with record breaking performances.
The exclusive combination of an ARM® Cortex®-M0+ core and STM32 ultra-low-power features, makes the STM32 L0 the best fit for applications operating on battery or supplied by energy harvesting.
The STM32 L0 offers dynamic voltage scaling, an ultra-low-power clock oscillator, LCD interface, comparator, DAC and hardware encryption.
New autonomous peripherals (including USART, I²C, 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.
Other value-added features such as 16-bit ADC (HW oversampling), crystal-less USB, short wake-up time 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.
The STM32 L0 is available with up to 64 Kbytes of Flash, 8 Kbytes of RAM and up to 2 Kbytes of embedded EEPROM (no emulation needed) in 32- to 64-pin packages, including a space-saving WLCSP36.
Current consumption reference values:
- Dynamic run mode: down to 87 μA/MHz
- Ultra-low-power mode + full RAM + low power timer: 440 nA (16 wakeup lines)
- Ultra-low-power mode + backup register: 250 nA (3 wakeup pins)
- Wake-up time: 3.5 µs
Software development for STM32 made easy with STM32Cube™
STM32Cube™ is an entirely free tool, providing
STM32CubeMX , a generator of initialization C-code for STM32 MCUs, based on a graphical user interface, and one embedded software library per series of STM32 products, containing the hardware abstraction layer (HAL) for the STM32 peripherals and a set of Middleware (RTOS, USB, TCP/IP, Graphics, …) based on components that are either ST developed or open source
The initialization code and HAL and Middleware library work with all STM32 compilers, the included project examples are set up for IAR, Keil, and the GCC based Atollic IDE.
STM32Cube comes with hundreds of application code examples and supports the STM32 F4, STM32 F3 STM32 F2, STM32 F0 and STM32 L0 series
