LPC2210 - read part ID revision (A or B) - gillesrobichon - Feb 4 11:19:16 2009
I'm looking for a way to read the revision of the LPC2210 used in our
product, Rev.A or Rev.B
NXP doc mentions a way to read CPU ID
Command "J"
Return Code CMD_SUCCESS followed by part identification number in
ASCII format.
Description This command is used to read the part identification
number.
Example "J"
In case of a LPC2210/2220, an answer to a read Part ID command is
0x0301FF12
(5046248210).
has anyone been able to read down to the revision ID of the chipset,
I'm interested to read whether this is a RevA or RevB,
thanks!
Gilles.

Be careful when looking at NXP's datasheets for "Read Part Identification";
I noticed that some user-manual revisions (likely old) have the same part
numbers for similarly-sized 213X and 214X parts, which I hope is an error.
