My question is for Philips group.  Some time ago on this forum was
information, that Philips plans to start this year production of USB
and then new CAM (LPC2139?) microcontrollers.  Now I am finishing a 
design of a new module with the LPC2129 and want to make the PCB,
if possible, to be compatible with the future CAM microcontroller.
I examined the LPC2138 documentation, and noticed, that only pin 17
has another functionality.  Pins 49 and 63 are still power, only 3.3V
instead of 1.8V.
Now my question.  I put a 0 Ohm resistor between the pin 17 and
pins 49, 63.  In case of the LPC2129 I will mount it and connect all
them to 1.8V source and for future microcontroller the resistor should
not be mounted and 49,63 pins I will connect to 3.3V source.  Is
my guess right?
I am sure, that the answer will be of common interest.
Great thanks in advance,

Varuzhan

Varuzhan,

the CAN device has not been defined yet. Every effort has been made 
to keep changes to the PCB minimized. This will also be the case for 
a device similar to the LPC2138 but with CAN. 

The power pins will be kept at the same pins. The challenge is going 
to be that CAN pins are on the same pins as the 32 kHz input of the 
RTC. 

Understanding your desire to know which pins are going to be what, 
please accept my apologies not knowing the exact pinconfiguration 
yet. 

Robert
