Description
STM32L476QGI6TR is a low‑power 32‑bit MCU from ST’s STM32L4 family, built around an ARM Cortex‑M4F core. Key points:
- Core and performance: Cortex‑M4F with FPU and DSP, up to about 80 MHz, optimized for energy efficiency.
- Voltage and power: operates from ~1.65–3.6 V with multiple low‑power modes (Run, Sleep, Stop, Standby) for battery‑powered designs.
- Memory and package: memory size and exact RAM depend on the specific package variant; this part belongs to a family offering hundreds of KB–a few hundred KB of Flash and tens–hundreds of KB RAM. Check the datasheet for exact counts for this package.
- Peripherals: rich mix including USB Full‑Speed (device/OTG), CAN, I2C, SPI, UART/USART, multiple timers, RTC, ADCs, DACs, DMA, and LCD controller; additional features vary by variant.
- Development: supported by STM32CubeMX/CubeIDE with HAL/LL libraries; programming via ST‑LINK; broad ecosystem and example projects.
- Applications: wearables, industrial IoT, sensors, and other energy‑efficient embedded systems.
