Any MCU from NXP can support separated address and data pins for external bus?

Norihiro — Thu, 31 Oct 2024 01:38:24 GMT

Hello,

I selected MCX Micro as a location for my question.

But this question is not for specific MCU family from NXP.

My question is, is there any MCUs from NXP that can support separated

address and data pins for external bus?

In my understanding, NXP's MCU that support the external bus interface

have multiplexed address/data pins.

Hi norihiromichiga,

MCX N only supports external memory over FlexSPI interface or SPI

Hope this will help you,

Hello Jun,

Thank you for your answer.

But as I posted in my first post, my quesiton is not limited to MCX series.

Does NXP have any series of MCU that can suppor seperated address and data bus of external bus interface?

Hi norihiromichiga ,

Thanks. I was considering MCX because this is MCX space.

Considering other MCUs, LPC17xx/18xx, LPC40xx integrates EMC module which has saperated data and address external bus. But these LPCs are legacy product which is not recommended for new design.

RT1060 RT1170 also support EMC. I would suggest you consider as well.

Hope this helps,

Hello Jun,

Thank you for your comment. I understood your point.

BTW, customer may have questions that are not classified to specific MCU like this question.

If there is a forum for general questions, it may be good for customers.
