1 MB Flash, 96 KB SRAM — the high-density STM32F103 option
This is the high-density variant in the STM32F103 value line, offering the largest on-chip memory footprint in the family for firmware-heavy applications like industrial motor drives, field-oriented control, CANopen gateways, and USB-capable instrumentation.
Motor-control peripheral set and connectivity
The peripheral list includes dedicated motor-control PWM timers, DMA, and a temperature sensor, alongside CAN, USB, SPI, I²C, and UART/USART interfaces. For a sensorless BLDC drive, the PWM timers and DMA can handle the commutation and current-sense sequencing in hardware, freeing the core for the control loop.
This means no last-time-buy window to manage and no forced redesign for obsolescence in the near term.
TR suffix — tape-and-reel delivery
The base part STM32F103RGT6 (tray) and this TR variant are electrically identical; the difference is only the shipping medium.
