概述

Description

STM32L475RCT6 is a low-power microcontroller from ST’s STM32L4 family. It uses a 32‑bit ARM Cortex‑M4F core (DSP/FPU) up to about 80 MHz and targets energy-efficient embedded apps.
Key specs (typical):
- Memory: up to 1 MB flash, up to 128 KB RAM
- Peripherals: USB Full‑Speed device, LCD controller, multiple timers, I2C/SPI/UART, ADCs/DACs, oper‑amps and comparators, crypto engine (AES, RNG), CRC
- Power: wide voltage range (1.65–3.6 V) with multiple low‑power modes (Sleep/STOP/Standby) and fast wakeup; RTC with LSE
- Security: hardware cryptography and option bytes for protection
- Package: commonly available in 64‑pin LQFP variants (and other packages)
Software and tools:
- STCubeMX/HAL or LL libraries; compatible with Keil, IAR, GCC
- Supported on Nucleo/Discovery boards for development
