STM32L475RCT6

STM32L475RCT6 is a member of STMicroelectronics’ STM32L4 ultra‑low‑power MCU family. It uses an ARM Cortex‑M4F core, offering a good balance of performance and energy efficiency for battery-powered and wearable apps. It runs up to about 80 MHz, supports a wide voltage range (roughly 1.65–3.6 V), and provides multiple low‑power modes to extend battery life.
Peripherals include USB Full‑Speed, an LCD/TFT controller, multiple ADCs and DACs, RNG and cryptographic accelerators, plus flexible timers and serial interfaces (USART/UART, SPI, I2C, I2S) and SDIO with DMA. Memory sizes and pin counts vary by device variant within the L475 family.
Typical use cases: wearables, sensors, IoT devices, portable medical equipment. Development is supported by STM32CubeMX/HAL and ST evaluation boards. For exact flash/RAM sizes, package/pinout, and available variants, consult the STM32L475RCT6 datasheet and reference manual.
