概述

Description

STM32L431VCI6 is STMicroelectronics’ ultra-low-power STM32L4 MCU in a 48‑pin LQFP (CI6) package. It uses an ARM Cortex‑M4F core, runs up to 80 MHz, and operates on 1.65–3.6 V. Memory varies by variant but typically includes hundreds of KB of Flash and tens of KB of RAM. It supports multiple power modes (Stop, Standby) for long battery life. Peripherals usually include GPIO, timers, ADCs, and serial interfaces (I2C, SPI, USART/UART) with USB FS where supported. DMA and a rich set of analog features help with sensing and control tasks. Development is supported by STM32CubeMX/HAL libraries and STM32CubeIDE, plus broad vendor/community tooling. Common applications: wearable and portable sensors, battery-powered IoT nodes, and other energy-constrained devices needing moderate performance with low power. For exact memory sizes, peripherals, and package details, refer to the official datasheet for this exact device package variant.

Equivalent

Not a direct cross-vendor equivalent. Closest ST options: other STM32L4/L4+-series MCUs with similar memory/peripherals (e.g., STM32L432, STM32L452, STM32L476 in comparable packages). Outside ST, common Cortex-M4F peers include NXP LPC55S6x/LPC55S69 and Microchip ATSAME54/ATSAME70. However, pinouts and peripherals differ; use datasheet cross-reference tools to confirm compatibility.
