STM32H743VIT6 vs STM32H743ZIT6

[eLKa]

Hello everyone.

Is it possible to directly replace STM32H743VIT6 processor with STM32H743ZIT6 without changing the program code? Will there be any differences in the performance of the DSP device with this processor?

Thanks in advance for your reply, Chris.

Hello,

It depends on how do you mean by direct replacement.

STM32H743VIT6 is 100 pin package while STM32H743ZIT6 is 144 pin package. So the only difference is the pin number / IOs:

Please refer to the datasheet Table 2 where the features of each part number are provided:

Thank you very much for your quick reply. I was mainly concerned with changes in the program code.

Apart of the PCB  footprint, the two part numbers have the same die. So you can replace STM32H743VIT6 by STM32H743ZIT6 without any issue.

The datasheet also tells you what all those suffix characters mean in the part number:

Thank you all for your answers. It helped me a lot. All you need to do is redesign the printed circuit board.
