Id parts in software

Started by embeddedjanitor September 8, 2004
Hi

I have a board that can work with either an LPC2119 or an LPC2129. I
want the flexibility so that I'm not just locked in to one part or
the other. For most things, I can treat these identically, but I'd
like to know if there is a way to identify the LPC2119 vs the LPC2129
at runtime.

Thanx

You should be able to get the chip ID using the appropriate IAP command.

Thanx

Yes I am aware of the IAP part Id thing and have that working.

Is there any specification on what the part Id means?

ie. From the part Id number how do I work out what part it is?

You should be able to get it from Philips.Also, you could just try it on the
chips you are using see what you get, and use that. It will probably change
from time to time, with revisions of the silicon, but part of it should
remain constant.

Errr, quite.

An arbitrary part Id number could be anything. root part, revision,
week code,...

I'll see if Philips can shed some light.

There is now a table of Part IDs in the file section.
