STM32L0 series of ultra-low-power MCUs
The STM32L0 series has been carefully 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 STM32L0 the best fit for applications operating on battery or supplied by energy harvesting and the world’s lowest power consumption MCU at 125°C. The STM32L0 MCUs have scored 135 in the standardized EEMBC™ ULPBench® tests that compare the efficiency of ultra-low-power microcontrollers.
The STM32L0 offers dynamic voltage scaling, an ultra-low-power clock oscillator, LCD interface, comparator, DAC, True Random Number Generation and hardware encryption (AES-128).
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.
Memory wise, the STM32L0 is available from 8 Kbytes up to 64 Kbytes of Flash, up to 20 Kbytes of RAM and up to 6 Kbytes of TRUE embedded EEPROM (no emulation needed).
Package wise the Series is available from 14-pin package up to 100 pins including various space-saving WLCSP package available on 25, 36 or 49-pin count.
