Is there a pin compatibility of dual core MCU with STM32H743BI ? I would like to upgrade my MCU to dual core.

Use the "List Pinout Compatible MCUs" in CubeMX.

The result of this says there is no pin compatible dual-core chip. The power pins are completely different.

Hello @subramani kp,

If you use the Cross selector feature (as explained in the article; How to find compatible devices for an MCU? STM32G473CB as example), you will find that STM32H745BITx is compatible with STM32H743BITx (98% match).

But as already said by @TDK, you need to pay attention to the power supply.

For that purpose, you need to refer to the 2nd section of the Getting started with STM32H74xI/G and STM32H75xI/G hardware development AN4938.

Chahinez.
