概述
Description
STM32L471VGT6TR is STMicroelectronics’ STM32L4 ultra-low-power microcontroller in the STM32L471 line. It uses a 32-bit ARM Cortex-M4F core (with FPU and DSP) and is optimized for battery-powered/energy‑efficient designs. It runs up to around 80 MHz and supports multiple low‑power modes for long battery life. Peripherals typically include analog blocks (12‑bit ADCs, DACs), timers, RTC, and a broad mix of digital interfaces (USART/UART, I2C, SPI, USB FS; CAN on some variants) plus optional LCD controller and other features depending on the exact package. The VGT6TR suffix encodes the device’s package/pin configuration and packaging (TR indicating Tape & Reel). For exact memory sizes, voltage ranges, current consumption, and peripheral availability, consult the official datasheet and product brief on ST’s website. Typical applications: wearables, IoT sensors, portable medical devices, and other energy‑constrained electronics.
