STM32H723ZGT6 vs STM32H743ZIT6 P2P compatibility

[Sandeep1]

Hi,

I am planning to replace STM32H723ZGT6 with the STM32H743ZIT6. I am interested in the following interfaces and using the respective in numbers MII/RMII(1 no.), SPI(1 no.), UART(4 no.), I2C(4 no.), QSPI(1 no.), OSPI(1 no.). Please do let me know if these two ICs are pin to pin compatible or drop in replacement of each other ? 

Regards,

Sandeep

They're pin to pin compatible. At long as they both have the peripherals you're using, and your clock settings and memory usage are within the bounds of both, it should be a drop in replacement. Note that there are difference in memory amount and allowable clock speeds.

Hello @Sandeep1 ,

As mentioned by@TDK they are pin to pin compatible.

You can check the compatibility pin by using the STM32CubeMX. This toolchain allows you to know the list of MCUs with Pinout compatible, you just need to start by creating a new project using your MCU part number (STM32H723ZGT6 in your case) and press Pinout to get the list of all compatible MCUs as presented in the below figures:

Note that also when compared STM32H723 to STM32H74x/75x devices, STM32H72/73x devices offer the following additional features:
• two OCTOSPI interfaces, instead of a single QUADSPI
• possibility to store encrypted code or data on external Octo-SPI memories (for STM32H73x devices)
• a parallel synchronous slave interface (PSSI)
• a digital temperature sensor
