Product details

Cortex-M4 with FPU — what the 72 MHz core buys you

The STM32F302R8T6TR: The Cortex-M4 core includes a single-precision floating-point unit (FPU) and DSP instructions, so you can run FOC motor-control loops or sensor-fusion algorithms without an external DSP.

Peripheral set — CAN, USB, and 12-bit ADC/DAC

The 15-channel 12-bit ADC and single 12-bit DAC handle analog sensing and output without an external converter. DMA, I²S, POR, PWM, and WDT round out the peripheral set for motor-drive timing and watchdog supervision.

Package and temperature grade — 64-LQFP, industrial range

Supply voltage spans 2.0 V to 3.6 V, so it runs from a single 3.3 V rail or a 3.6 V Li-ion cell with margin.

Frequently asked questions

What is the difference between STM32F302R8T6 and STM32F302R8T6TR?

The STM32F302R8T6TR is the Tape & Reel (TR) packaging variant of the STM32F302R8T6. The silicon and firmware are identical; the suffix 'TR' indicates the part is supplied on a reel for automated pick-and-place assembly, while the base part number typically ships in trays or tubes. For volume production, order the TR suffix; for prototyping or small runs, the Cut Tape (CT) option may be more economical.
