STM32 L1 Ultra-Low-Power MCUs

STMicroelectronics STM32 L1 Ultra-Low-Power MCUs are Arm® Cortex®-M3-based STM32 using ultra-low-leakage process technology with an innovative autonomous dynamic voltage scaling and 5 low-power modes offering unprecedented platform flexibility to fit any application. The STM32 L1 series extends the ultra-low-power concept with no compromise on performance. The STM32 L1 offers dynamic voltage scaling, an ultra-low-power clock oscillator, LCD interface, comparator, DAC and hardware encryption. More than just ultra-low-power MCUs, the STM32 L1 series offers a wide portfolio of features, memory sizes and package pin counts. Combining ultra-low power and performance, the portfolio covers from 32 to 512Kbytes of Flash memory (with up to 80Kbytes of SDRAM and 16Kbytes of true embedded EEPROM) and from 48 to 144 pins.
