Product details

The STM32F103V8T6TR: The 80 I/O lines in the 100-LQFP package give enough headroom for sensor arrays, display interfaces, and parallel bus connections in a single-chip design.

Peripheral set and connectivity — where it fits

This MCU integrates a rich set of peripherals: DMA for memory-to-peripheral transfers without CPU load, motor-control PWM for brushless DC or stepper drives, plus PVD, POR, and PDR for supply supervision. The internal oscillator reduces external BOM count, though a crystal can be added for tighter timing accuracy.

The 16-channel 12-bit ADC covers analog input acquisition for current sensing, temperature monitoring, or potentiometer feedback without an external converter.

Frequently asked questions

What is the difference between STM32F103V8T6 and STM32F103V8T6TR?

The die and functional specifications are identical. The STM32F103V8T6TR suffix indicates Tape & Reel packaging for automated pick-and-place assembly, while the STM32F103V8T6 typically ships in tray or tube. Both are the same 100-LQFP device.
