Philips datasheet department...

2005-02-23 by Lasse Madsen

Dear Philips,

I have some suggestions for making your LPC series datasheets better...
I've always thought that your datasheets where top of the line, easy to read
and quick to get around in... (Logic, PLL, etc..) 


Please let me give you some suggestions and comments:

1)
Sadly I find it quite difficult to even find a suitable datasheet for my 
Part LPC2129... getting to the specific part page was easy (applause for
that! (Some manufacturers -ST for instance couldn't find a donkey in a
toilet)

But!

Now I'm at this page: 
http://www.semiconductors.philips.com/pip/LPC2129.html

I press the datasheet link and I'm given a 34 page datasheet, Wow excuse me
but I guess this parts have more to it than just the supply voltages! 

Come on Philips you can do better, why did I have to search your website for
an hour and ending up comparing pins on the LPC2114 and the LPC2129 to find
a "match" or even a datasheet with more than 34 pages! This discourages me
to get started with that part when the manufacturer not even knows how it
works (or cant supply a real datasheet for it)!

2)
Another thing... I miss C and Assembly examples. A lot of microprocessor
manufacturers has examples for everything that's just a bit special such as
correct watchdog initialization etc. look at Atmel ATmega128 that datasheet
is like the holy bible it self. I have seen datasheets like that from you
before, but I'm missing them on the LPC parts.

Another datasheet thing... The counter/timer/capture initialization is very
confusing! I'm missing connection diagrams showing the logic inside how the
actual "travel path is" from pin to MPU, the Prescaler logic etc. block
diagrams etc. Some people like to read themselves to an answer, and some of
us (like me for instance) learn better if the text is illustrated with some
diagrams.

Again look at Atmel's ATmega128 datasheet look how easy Its all explained
how they carry you through the registers etc. 

Just for the record I'm not a slow reader, slow learner, dyslectic etc.
And I'm not a crackpot either having some insane vengeance towards Philips
products. In fact I'm an incarnated Philips fan not only loving your
semiconductors but also your consumer products :)

I hope you will take my humble option into consideration as your logo says
"Lets make things better" - and I hope you will... 

We are not all bookworm layers that can read between the lines :-D 

Best regards
Lasse Madsen
