Product details

Package and I/O — 100-LQFP with 86 accessible pins

Housed in a 100-LQFP package (14x14 mm body), the STM32G441VBT6 brings out 86 general-purpose I/O pins. That's enough for a parallel LCD bus, a full set of encoder inputs, and several serial interfaces without multiplexing conflicts. The surface-mount LQFP footprint is standard across the STM32G4 100-pin variants, so a board laid out for the STM32G431 or STM32G474 will accept this part with no PCB change — the pinout is consistent within the family.

Frequently asked questions

Is the STM32G441VBT6 compatible with the STM32G431 as a drop-in replacement?

The STM32G441VBT6 shares the same 100-LQFP package and pinout as the STM32G431 family. It is pin-compatible, so a board designed for the STM32G431 can accept the STM32G441VBT6 without a PCB layout change. The key difference is the 170 MHz core speed versus the 170 MHz on the G431 — both run at the same maximum clock. Check the specific peripheral set differences (ADC/DAC channel count, memory size) against your firmware requirements before swapping.
