Product details

That core includes a single-cycle multiply and a hardware FPU, so it handles real-time control loops (motor FOC, digital power, audio filtering) without an external DSP.

STMicroelectronics lists the STM32F412VET3TR as an active product with no end-of-life notification. There is no last-time-buy pressure, and the part is supported by ST's long-term commitment to the STM32F4 series.

Supplied in a 100-pin LQFP package (14x14 mm body) on Tape & Reel — the TR suffix. The LQFP is a hand-solderable, inspectable package that suits both prototype rework and high-volume reflow.

Frequently asked questions

What is the difference between STM32F412VET3TR and STM32F412VET6?

The two parts share the same die, package, and electrical specifications. The difference is the shipping medium: the VET3TR suffix denotes Tape & Reel packaging for automated pick-and-place, while the VET6 suffix typically ships in trays or tubes. Functionally they are identical — the TR variant is the one you want for high-volume assembly lines.

Does STM32F412VET3TR come in tape and reel packaging?

Yes, the TR suffix explicitly indicates Tape & Reel packaging. This is the standard reel format for automated SMT placement. The reel quantity is manufacturer-defined; check the ST shipping specification for the exact count per reel.

Can STM32F412VET3TR replace STM32F412VET6?

Yes, the STM32F412VET3TR is a direct functional replacement for the STM32F412VET6. Both use the same 100-LQFP package, same 100 MHz Cortex-M4 core, same memory sizes, and same temperature range. The only difference is the packaging format — Tape & Reel versus tray/tube — so the TR variant drops straight into the same PCB footprint.
