Hi All

I have been using the LPC2106 in LQFP48 for some time now. This is 
also available HVQFN48 now - it wasn't when we started production - 
and I want to move to this to reduce height in future products.

I also want to use the SPI interface but know that there is a bug in 
the chips we have at the present in Master mode (SSEL must be tied 
high) which is not so back but have never been able to get the thing 
to do anything sensible in slave mode (rx fine but tx unpredicatable 
at the best).

So the question is this. Is it possible that the SPI bugs will be 
cured in the new devices (moving to the new housing) or are the dies 
identical and so still with the known restrictions? I would really 
like to use the SPI as slave (although can live with master mode if 
absolutely necessary).

I have HVQFN48 samples on the way and am preparing a new PCB for 
tests - if I could be sure that there is an improvement, I could set 
up the SPI as I would really like it to be on the board. Can anyone 
confirm or must I assume the error?

Many thanks in advance.

Mark,

the new package is still the old existing device inside. There is 
going to be a version for the LPC2106 with all bugs known today 
fixed to be released in second quarter 2006.
