概述

Description

STM32L476QGI6TR is STMicroelectronics’ ultra-low-power MCU from the STM32L4+ family. It uses the ARM Cortex-M4F core (with FPU and DSP features) and runs up to about 80 MHz, optimized for energy efficiency in battery-powered devices. It integrates on‑chip Flash and SRAM (sizes vary by variant) and offers a rich peripheral set.
Key features:
- Peripherals: ADCs, DAC, op-amps, comparators, timers, RTC, I2C, SPI, USART/UART/I2S, CAN, USB FS, and SDIO.
- LCD controller for graphics/display support.
- Security/reliability: cryptographic accelerators, RNG, CRC, MPU.
- Power management: multiple low‑power modes (Run, Sleep, Stop, Standby) with fast wakeup and DMA.
- Development: supported by STM32CubeMX, HAL/LL libraries, and SWD debugging.
Package: QGI6TR indicates a specific 64‑pin package with Tape & Reel packaging.
Typical uses: wearables, sensors, portable instrumentation, and other low‑power embedded applications requiring integrated peripherals and long battery life.

Features

Key features of STM32L476QGI6TR (100‑pin LQFP, TR):
