Replacement for STM32H753ZI

Hi,

 

I am looking for the STM32H series part with more GPIOs and Timers than STM32H753ZI. Can you please suggest me some of the options in H series?

Below is my requirement

Hello @DJ7 ,

When you say STM32H, it could be STM32H5 or STM32H7.

Anyway, you can refer to the datasheet. For example in case of STM32H742xI/G /STM32H743x / STM32H753 Table 2: it shows all the instances available on the MCU. 

For example for the GPIOs number, it depends on the package:

SofLit_0-1727278239695.png

SPI/I2C/USART instances:

SofLit_1-1727278411428.png

But becarefull, you need to check if all these instances could be used in parallel.

Hello @DJ7 and welcome to the ST Community.

For such a use case, I suggest you use the STM32-MCU-FINDER this tool where you could define what you want exactly, and the tool will give you all available options.

Best Regards.
