描述：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
