STM32F051R8T7TR

STM32F051R8T7TR is an STMicroelectronics MCU from the STM32F0 family. It targets low‑cost, low‑power embedded applications and uses a 32‑bit ARM Cortex‑M0 core running up to 48 MHz. It combines on‑chip flash and RAM with a broad peripheral set (GPIO, timers, ADC, and serial interfaces such as USART/SPI/I2C; USB device is available on applicable SKUs). The “R8T7” suffix denotes a 64‑pin LQFP package, while “TR” typically indicates tape‑and‑reel packaging. The device supports multiple power modes and standard development tools (STM32CubeMX, HAL/LL libraries). Use cases include simple control tasks, peripheral interfacing, USB device applications, and compact IoT nodes. For exact flash and RAM sizes and the precise peripheral list, consult the official datasheet for the F051R8T7TR variant.
