STM32L071RBT6 ST Microcontroller

The STM32L071RBT6 is an ultra-low-power Arm Cortex-M0+ 32-bit MCU from STMicroelectronics in LQFP-64 package, operating at 32 MHz with 128 KB Flash, 20 KB SRAM, and 6 KB embedded EEPROM . For selection, verify supply from 1.65V to 3.6V, confirm -40°C to +85°C operation, note 51 I/Os, 12-bit ADC (hardware oversampling up to 16-bit resolution), calendar RTC, low-power timers, communication interfaces including USART, SPI, I2C, and hardware AES-128 encryption module . Features include ultra-low power consumption of 87 µA/MHz in run mode, 440 nA standby mode with full RAM retention and low-power timer, 250 nA standby mode with backup registers, and 3.5 µs wakeup time. Ideal for battery-powered devices (gas/water meters, keyboards, mice), medical instruments, wireless sensors, IoT nodes, and industrial applications requiring ultra-low power consumption with EEPROM integration and hardware security .
