Product details

What the 180 MHz core means for your design

That core speed, combined with a single-cycle multiply and hardware FPU, gives it enough headroom for real-time control loops, sensor fusion, and basic DSP without an external co-processor.

Peripheral set and connectivity fit

This MCU carries a broad peripheral set: CANbus, USB OTG, multiple SPI and I²C interfaces, plus SAI for audio and SPDIF-Rx for digital audio input. The 81 I/O pins in the 100-LQFP package give enough GPIO for parallel buses or a large sensor array. The EBI/EMI interface can connect external SRAM or NOR Flash, useful when the internal 512 KB is tight.

The part is ROHS3 compliant.

Housed in a 100-LQFP (14x14 mm) surface-mount package, the STM32F446VET6TR is suited for standard reflow assembly.

Frequently asked questions

What is the difference between STM32F446VET6TR and STM32F446VET6?

The STM32F446VET6TR is the tape-and-reel packaged variant of the STM32F446VET6. The electrical and functional specifications are identical; the only difference is the shipping medium — Tape & Reel (TR) for automated pick-and-place versus the tray or tube packaging of the base part number.
