I was under the impression that the LPC2104/5/6 series were older
and possibly buggier than newer parts.  I have designed in the 
LPC2102/3 and the LPC2144 parts and am about ready to roll on the 
software.
I tend to use these parts to the max BTW as far as PWM, UART, A/D 
peripheral and interrupt usage go, although in this project I only
need 2 PWM outputs (luckily, because the 2nd UART uses up the other
PWM pins).

So far I've had good communications luck with the 2012 on my first 
board.  (Haven't gotten into high gear programming yet)

Am I in for big surprises? I am prepared for a few issues such as
spurious interrupts and possible A/D problems if inputs go above
Vref, etc...   I do have a high regard for Philips products in general
and have had good luck with Philips in the past.

PS, last parts I used were Atmel AVR ATMega 32s, the architecture
of which was great and are were finally good parts as soon as
Atmel fixed their bad, bad, silicon problem which almost put my last 
company out of business. (Yes, I'm bald now) Because of Atmels lack 
of support, secrecy and denial of that problem, I will not use Atmel 
any more.


Also, is there any kind of list of commercial products that use the 
Philips LPC series ??  (or possibly a thread on this forum?)

My recent product designs are generaly power supply, LCD, 
communications oriented.

Do you mean 8088 variety maybe ??
