Maximum throughput while using DA14580 over external SPI

Hi,

I have a custom board where the DA14580 is used as a secondary/slave MCU with another primary MCU. I would like to know as to what maximum throughput can be hit while using a payload of the default 20 bytes before SPI or any other factor becomes a bottleneck. Are there any official figures or any testing done for this?

Thanks

Hi tsgowtham

Hi tsgowtham

This is the only document we have regarding DA14580 External processor interface over SPI :

https://www.dialog-semiconductor.com/sites/default/files/um-b-013_da14580_581_external_processor_interface_over_spi_v1.3.pdf

Could you please share a high-level description of your project? Why you have decided to use the DA14580?

If you are starting a new design, we would strongly recommend starting with DA14531 or DA14585/586 products and our latest SDK6.0.14, as it is much more improved. We have a lot of code examples and improved documentation, and there is also software roadmap support. There is no software roadmap support for DA14580 product family and SDK5.

Thanks, PM_Dialog
