Hi,

have a look at the FAQ here:

http://www.standardics.philips.com/support/faq/microcontrollers/

I also added a link in the link section named 
"Philips FAQ for LPC2000 devices"

Regards, Robert

Hi Robert.

Since you brught changes to the site...
Earlier this week I had to program the flash of a 2148, so I went to get 
the philips flash utility. By browsing and searching the site all I 
could find is an old version, that doesn't support this chip. I 
eventually could find a version that worked by searching with google, 
but even though not on the first search page.... It think it would be 
nice to have tha latest version easily avaiable, preferably in each 
procesor page...

Saudações,
Ricardo

Hi Robert,
Great starting point. However, I find the information (below) inaccurate
(re: number of registers in Thumb state):
'Hi registers', r8-r15, are still present, it is that only instructions
ADD, MOV and CMP can make use of them.

See Steve Furber, pg 190;  and David Seal's ARM ARM, section 6.4.1

This is quite common misperception about Thumb state.

I hope this clarification is taken in a constructive way.

Best regards

Roger
	Q: Having the Thumb core allows more compact code and better
performance. Are there any trade offs?    A:  Thumb is a 16-bit
compressed instruction set that is decoded by theThumb core into full
32-bit instructions that are then fed into an ARMcore for execution.
Thumb increases code density drastically. The tradeoffs are that the
Thumb instruction set loses the conditionalinstruction capability and
can only address the first eight registers of the processor.

Hi Ricardo,

thank you for your feedback and I do understand (and sometimes 
share) your frustration about finding information like the ISP 
program latest version on the Philips website. 
I would highly recommend to start the search for LPC2000 information 
here: http://www.philips.com/microcontrollers

this forwards you to this subdomain:
http://www.standardics.philips.com/microcontrollers/
from here, there are links to LPC2000, LPC900... in the text of the 
top center box

A shortcut to all the LPC2000 information is this:
--------------------------------------------------
http://www.standardics.philips.com/products/lpc2000/all/

Once you find your product, please click the "+" sign and from there 
it is rather easy. 

The ISP program can be found under "tools"

Robert

 Q Can the internal pull-up resistors on port pins be disabled?
 A No, they cannot be disabled, and they consume typically 50mA per pin.

this cannot be true, can it?  are you really talking about "50mA" or
would that be 50 micro amperes?

Clemens, it is microamps, you are absolutley right. My apologies. At 
least this one is rather obvious.
