Product details

32-LQFP footprint and supply range — board-level fit

The 32-LQFP package (7x7 mm body) with 26 I/Os fits space-constrained PCBs where a larger QFP or BGA would overrun the board edge.

It is ROHS3 compliant.

The 170 MHz Cortex-M4 with FPU and DSP instructions handles sensor fusion and FOC motor algorithms within that envelope.

Frequently asked questions

Is STM32G431K6T6 active or obsolete?

The STM32G431K6T6 is listed as active by STMicroelectronics.

Does STM32G431K6T6 support CAN FD?

The STM32G431K6T6 includes a CANbus interface. The STM32G4 series supports CAN FD (Flexible Data-Rate) on its CAN peripheral, so this part is capable of CAN FD operation.

Can STM32G431K6T6 be programmed with ST-Link?

Yes, the STM32G431K6T6 uses the standard ARM Serial Wire Debug (SWD) interface, which is supported by ST-Link programmers. The debug port remains accessible even with the watchdog enabled, per the STM32G4 reference manual.

What is the difference between STM32G431K6T6 and STM32G431C6T6?

Both are STM32G431 parts with the same core, memory, and peripheral set. The difference is the package: the K6T6 is in a 32-LQFP (7x7 mm), while the C6T6 is in a 48-LQFP (7x7 mm) with more I/Os. The K6T6 has 26 I/Os versus the C6T6's higher count.
