In the process of writing a simple demo program for a new IAP module for Armaide
we've found that the Part ID codes for the LPC2101/02 parts are missing
from the documentation. (UM10161, Rev 4. 13 May 2009. Section 9.11, Table 228:
LPC2101/02/03 part identification numbers)
A value for LPC2103 is listed. Are the other two the same? If not, what should
they be?
TIA,

Hi Chris
According to the Device Database in FLASH-Magic all three parts have the same ID (Signature: 327441 (0x0004FF11)). Reading an LPC2103 confirms this but I have never had LPC2101 or LPC2102s to verify.
However I have a question about the LPC2148. According to the user's manual August 15. 2005 [the one on the NXP web site belonging to the part] this should have (Signature: 196389 (0x0002FF25)). According to FLASH Magic is should be Signature: 67305253 (0x0402FF25). The part on my board also returns this.
This suggest to me that the signature has been updated since the user's manual was released. Therefore I don't know whether the User's manuals are generally reliable references for this.

Hi,
Referring to the LPC2148, the correct ID is 0x0402FF25
See the July 2006 UM version here:

Hi Ken
One day I must work out how to get the up-to-date user's manuals. By just going to the processor there are generally only out-dated ones...
Eg. Just going to the LPC2148 [MCU -> ARM7 -> LPC2148] still gives the old one from 2005 with old ID:
http://www.nxp.com/#/pip/pip=[pip=LPC2141_42_44_46_48_4]|pp=[t=pip,i=LPC2141_42_44_46_48_4]

There appears to be two quite different websites with different versions of the user manuals on each. I've found generally that http://ics.nxp.com has later versions of the manuals than http://www.nxp.com. However, some of the links on 'ics' take you to the other site anyway ...
Thanks for your previous reply about the LPC2101/2/3.
Cheers,
Chris
