STM32L072KZU6

STM32L072KZU6 is an ultra low-power Arm Cortex-M0+ MCU. It incorporates the connectivity power of the universal serial bus (USB 2.0 crystal-less) with the high-performance Arm Cortex-M0+ 32bit RISC core operating at a 32MHz frequency, a memory protection unit (MPU), highspeed embedded memories (upto 192Kbytes of flash program memory, 6Kbytes of data EEPROM and 20Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals. It provides high power efficiency for a wide range of performance. It is achieved with a large choice of internal and external clock sources, an internal voltage adaptation and several low-power modes. It also includes a real-time clock and a set of backup registers that remain powered in Standby mode. It is used in applications such as gas/water meters and industrial sensors, healthcare and fitness equipment, remote control and user interface, PC peripherals, gaming, GPS equipment, alarm system, wired and wireless sensors, and video intercom.
