ST’s ultra-low-power MCU platform is based on a proprietary ultra-low-leakage technology and optimized design.
The wide portfolio offers a large choice of MCU from the STM8L (8-bit proprietary core) up to the STM32L4 (ARM® Cortex®-M4) including the STM32L0 (ARM® Cortex®-M0+) and the STM32L1 (ARM® Cortex®-M3). ST’s ultra-low-power solution is the right choice for applications operating on battery or supplied by energy harvesting, requiring an extra-long life.
The STM8L/STM32L solutions with the industry’s lowest current variation between 25 and 125 °C guarantees outstandingly low current consumption at elevated temperatures. The MCUs reach the industry's lowest power consumption of 330 nA in lowest power mode with SRAM retention. Wake-up times have also been taken into consideration and are as low as 3.5 µs from Stop mode.
The new STM32L4 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) and innovative features.
