STMicroelectronics has classified the STM32F103RFT6JTR as Obsolete. No official replacement order code is listed by ST for this specific variant, so a pin-compatible alternative should be qualified on your bench before committing the BOM.
Peripheral fit — CAN, USB, and motor-control PWM in one package
The peripheral integration on this die saves a board-level CAN transceiver interface and a separate USB controller for many designs. The motor-control PWM timer with complementary outputs and programmable dead-time is directly wired for three-phase inverter drive — a common topology in brushless DC and permanent-magnet synchronous motor controllers. The dual 12-bit DACs can generate analog reference or offset voltages, while the 16-channel 12-bit ADC with injected conversion mode handles simultaneous sampling for multi-phase current sensing.
