Can we do XiP with STM32L476RE? Will the performance be good with running code from external memory?

[SS.5]

Hello,

I am using STM32L476RE and want to do XiP. So will it support XiP?

Will the performance be good with running code from external memory?

TIA

I believe it supports QSPI, other L4's do. Would take a couple of hours of engineering time to test specifics.

Sorry not benchmarked it, but several L4 DISCO/EVAL boards with QSPI that you could test with.

The CM4 doesn't having caching, so external memory is definitely slower, perhaps 2x or 3x, depend on memory and settings. The Micron parts support DDR.

Performance will be adequate, put high stress code in internal RAM/FLASH
