STM32L011G4U6TR

STM32L011G4U6TR is STMicroelectronics’ ultra-low-power MCU from the STM32L0 family. It uses a 32‑bit ARM Cortex‑M0+ core, runs up to 32 MHz, and targets battery-powered/IoT applications with very low active and sleep currents and multiple energy modes. The G4U6 variant defines the on‑chip Flash/RAM sizes and package; exact memory is specified in the datasheet. Peripherals typically include GPIO, timers (PWM), ADC, I2C, SPI, UART, DMA, and RTC. It supports power-saving features like stop/sleep modes and VBAT backup, making it suitable for sensors, wearables, environmental monitors, and other micro‑power nodes. Development is supported by ST tools (STM32CubeMX, HAL/LL libraries). For precise specs, consult the official datasheet/product page; the TR suffix denotes tape‑and‑reel packaging.
