The STM32L072KZT6 is an ultra-low-power ARM Cortex-M0+ microcontroller unit (MCU) with a 192KB flash memory, 32MHz CPU, and USB manufactured by STMicroelectronics. This MCU is built to be highly energy efficient and can potentially run up to an entire year while still consuming minimal energy. The processor includes Cortex-M0+ core and various integrated features such as full-speed USB 2.0 OTG, 1x I2C, 4x SPI, and 16-bit timers with DMA controller, 12-bit ADC, comparator, temperature sensor, and LCD controller. The STM32L072KZT6 also uses ST Power Shield technology to reduce power consumption further and features multiple low-power modes and a variety of power supply management options. It is ideal for applications in healthcare, building automation, sensing, and lighting.
