OCTOSPI on STM32U5F9ZJT6Q

[Ivica]

Dear, 

Can you confirm that OCTOSPI P2 is available only on WLCSP208 and TFBGA216 packages of this series? 

I wanted to use both OCTOSPI interfaces in LQFP144, but noticed that there is missing only OCTOSPIM_P2_IO3 line in it, so my conclusion is that LQFP144 supports only one OCTOSPI. Is that right? 

Thank you.

Hello @Ivica,

According to the datasheet DS14395 Rev 2 Table 2. STM32U5Fxxx features and peripheral counts.

The STM32U5F9ZJ supports only one OCTOSPI interface. If you want to use two XSPIs interfaces with STM32U5F9ZJ package, I recommend you to use the OCTOSPI interface and HSPI interface, which are supported on STM32U5F9ZJ package.

Thank you.

Is there a way to mux/map via the SPIM provided one can escape OCTOSPIM_P2_NCS on exposed pins?

Thank you @KDJEM.1 I missed this table. Then it is clear regarding OCTOSPI.

Hello @Tesla DeLorean

Thank you for bringing this to our attention.

I will check internally is there any restriction to use the multiplexed mode on STM32U5F9ZJ? And there a way to mux/map via the SPIM provided to escape OCTOSPIM_P2_NCS?

Internal ticket number: 199853 (This is an internal tracking number and is not accessible or usable by customers).

Thank you.
