Description
STM32F105R8T6TR is STMicroelectronics’ 32-bit STM32F1 Connectivity Line MCU, powered by the ARM Cortex-M3 core and capable of up to about 72 MHz. It targets mid-range embedded applications needing USB connectivity and CAN networking, with a rich peripheral set (SPI, I2C, USART, ADCs, timers, DMA, etc.). Memory and I/O vary by subvariant; the R8 family typically provides up to 128 KB of Flash and tens of KB of RAM (exact values depend on the specific part). The suffixes T6/TR indicate a 64‑pin (LQFP) package with Tape & Reel packaging (TR). Development is supported by ST’s HAL/LL libraries and STM32CubeIDE/CODE headers, making it suitable for USB device/host, automotive CAN, and general embedded projects. For exact specs (clock, RAM, peripherals), consult the official datasheet for the precise variant.
Equivalent
Direct cross-vendor equivalents do not exist; the device is ST’s Connectivity line with USB/CAN. Closest ST equivalents are:
- STM32F105R8T6 (same silicon, standard package)
- STM32F107VCT6 (USB OTG FS + CAN, higher pin count)
Packaging variants: STM32F105R8T6TR is the tape-and-reel version of STM32F105R8T6. For exact pinout, check ST cross-ref or your distributor.
