STM32U5G9J-DK2 & Flash Memory

[Dirty_Burner]

All,

My team is looking at designing a PCB around the STM32U5G9-DK2 development board and are running into some issues. The development board uses a flash memory IC "MX66LM1G45GXDI00" but the BSP example driver for the board only contains "MX66UW1G45G" information.

Is there a reason the development board only references this other flash memory IC in CubeIDE and if so will this driver still work for the development boards IC?

Thank You,

Hello @Dirty_Burner , 

Based on the MX66UW1G45G datasheet and MX66UW1G45G BSP component driver , the flash memory IC on STM32U5G9-DK2 board (MX66LM1G45GXDI00) belongs to the same family and shares the same core specifications. Therefore, the BSP driver for MX66UW1G45G is fully compatible and can be used with the MX66LM1G45GXDI00 without any issues.
For more information, you can check the Ordering Information section in the datasheet, which provides detailed component specifications and variants. Please see the screenshots below for reference.
