Is there a problem when I run the same program on STM32F723ZEI6 and STM32F723ZET6?

[裕井上.1]

I'm considering changing from STM32F723ZEI6 to STM32F723ZET6.

[Question]

・Is there a problem when I run the same program?

・Does they have the same functionality?

Hello @裕晶 井上​ ,

Weclome to the STM32 Community =)

These two devices do not have the same package:

• STM32F723ZEI6 :UFBGA 144 package (7x7x0.6 P 0.5 mm)
• STM32F723ZET6 : LQFP 144 package (20x20x1.4 mm)

You have to check the pinout in the STM32F723xx datasheet , Table 10. STM32F722xx and STM32F723xx pin and ball definition.

 

You can use the STM32CubeMX tool, which offers the features to compare the characteristics of two or more MCUs through the "Cross Selector" tab, and to display the list of compatible MCUs, then export your current project configuration to a compatible MCU.

I advise you to refer to the UM1718 in section "Cross selector" and "Tutorial 5: Exporting current project configuration to a compatible MCU"

 

Hope this helps you.

I have attached the Excel file containing a comparison of the characteristics and features between these devices.
