Programatic way to determine which LPC43x0 I'm running on

tmullanix — Thu, 19 Aug 2021 22:49:48 GMT

Hi,

I thought there would be a device register I could query to determine the flavor of LPC43x0 my application is running on. I could not find it in the datasheet. What's the best way for the application to determine this?

Thanks,

Todd

Hi, Todd,

For the flashless LPC43xx family for example LPC43x0, the IAP commands are not supported, but the ISP commands are supported.

You can use ISP commands to read the part identification number with the following commands J, but it is not possible to read a register to get the ID or to execute a function in IAP, because IAP is not supported for flashless part.

Hope it can help you

Hi XiangJun,

Thanks for the quick reply. Which document did the table you attached come from?

Thanks,

Hi, Todd,

I refer to UM10503.pdf, which can be downloaded from the link:
