STM32® 32-bit MCU Family

Leading Supplier of ARM® Cortex®-M Microcontrollers

STM32L1 Series of Ultra-Low-Power MCUs

STMicroelectronics ARM® Cortex®-M3-based STM32 L1 series uses ST’s proprietary 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.

As for the STM32 L0 and STM8 L, 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 512 Kbytes of Flash memory (with up to 80 Kbytes of SDRAM and 16 Kbytes of true embedded EEPROM) and from 48 to 144 pins.

• Innovative architecture: voltage scaling and ultra-low-power MSI oscillator
• Embedded peripherals, such as USB, LCD interface, op amp, comparators, ADC with fast on/off mode, DAC, capacitive touch and AES
• Ultra-low-power mode with real-time clock: 900 nA power consumption with backup registers
