STM32L011G4U6TR

STM32L011G4U6TR is a small, ultra‑low‑power MCU from ST’s STM32L0 family. It uses an ARM Cortex‑M0+ core, runs up to about 32 MHz, and is designed for battery-powered, space‑limited devices.
Key points
- Very low power: multiple sleep/stop modes with microamp-level current in deep sleep; supports 1.65–3.6 V operation.
- Small footprint: 20‑pin package (G4U6 variant) with a compact I/O count suitable for tight envelopes. TR suffix indicates tape-and-reel packaging.
- Peripherals: typical STM32L0 mix—12‑bit ADC, comparators, timers, RTC, and basic serial interfaces (USART/UART, I2C, SPI). Useful for sensing, simple control, timers, and lightweight IoT nodes.
- Memory: modest Flash/RAM tuned for small, cost‑effective applications (exact sizes depend on the exact variant/package).
- Development: supported via STM32CubeMX/HAL, with ST documentation (datasheet, reference manual) guiding pinout, electrical specs, and power modes.
