case about nRF54L15 & nRF54LM20 sQSPI sEMMC SPI

[peter.min]

Hi,

1.Can the sQSPI and SPI functions of nRF54L15 operate simultaneously at 32 MHz on the P2 port?
2.Can the sEMMC and SPI of nRF54L15 operate simultaneously at 32 MHz on the P2 port?
3.Can the sEMMC and sQSPI of nRF54L15 operate simultaneously at 32 MHz on the P2 port?

4.Can the sQSPI and SPI functions of nRF54LM20 operate simultaneously at 32 MHz on the P2 port?
5.Can the sEMMC and SPI of nRF54LM20 operate simultaneously at 32 MHz on the P2 port?
6.Can the sEMMC and sQSPI of nRF54LM20 operate simultaneously at 32 MHz on the P2 port?

Best regards,

Hi

Unfortunately the answer to all of these questions are no, as all these peripherals use the same dedicated GPIOs to be able to run in the extra high drive mode. You will be restricted to either sQSPI or sEMMC as these use the same dedicated GPIOs and the same instantiation in the VPR core. The GPIOs in question are P2.00-P2.05.

But high speed SPI can be set on the P2.06-P2.10 pins, and should be possible to run concurrently with a soft peripheral on both the nRF54L15 and nRF54LM20.

Hi Simon,

P2.06, P2.08, P2.09, P2.10, P2.07 - These can also be used for high-speed SPI. I used P2.00-P2.05 to create a high-speed 32mHz sEMMC, but can I use P2.06-P2.10 for a high-speed 32mHz SPI instead?
