概要

Description

STM32F105R8T6TR is STMicroelectronics’ STM32F1 Connectivity Line microcontroller. It uses a 32‑bit ARM Cortex‑M3 core running up to 72 MHz and provides a typical mix of memory and peripherals for embedded connectivity tasks: about 128 KB of flash and tens of KB of RAM, USB 2.0 OTG full‑speed, Ethernet MAC (RMII), CAN 2.0B, plus multiple USART/SPI/I2C ports and SDIO. It also includes DMA, timers with PWM, 12‑bit ADCs, CRC, RNG, and RTC, with support for external memory interfaces via FSMC in some configurations. The T6 suffix indicates a 64‑pin LQFP package, and the TR suffix denotes Tape‑&‑Reel packaging. Common applications include USB/Ethernet bridges, industrial control, data logging, and other networked or motor‑control devices. Development tools include STM32CubeMX, HAL/LL drivers, and standard SWD/JTAG debuggers.
