nRF52811 supports XIP (Execution in Place) feature ?

[justNordic]

Hi Folks,

Can you please let me know if nRF52811 supports XIP (Execution in Place) feature where I can use SPI NOR Flash to the SoC and execute my code directly from Flash?

Basically, nRF52811 is relatively new SoC and supports both LR and Direction Finding features. It has RAM of 24 KB. So I was just wondering if it can support SPI NOR Flash by any means?

Thanks,

Gautam

Hi Gautam

Only devices that support the QSPI interface suppors XIP, as this interface is a requirement for high bandwidth communication with the external memory device. 

The nRF52811 doesn't have a QSPI interface unfortunately, which means it also doesn't support XIP. 

At the moment the only Nordic device with  QSPI and XIP support is the nRF52840. 

Best regards
