When the LPC932 was newly released, I read some scary reports on the web and did not use them in my products, now I have purchased some LPC921s and I am trying to program them, I have already locked up 4 of them, it seems very difficult to start with these chips, even though there are three methods to work with the ISP (apart from the ICP)none of them are working at the moment.
There was never a problem with "reliability" of the LPC932 there was a lot of problems with certain things that did not work as stated in the early revisions of the chip. They worked as stated in the datasheet and the errata. At least Philips, as opposed to some other manufacturers, has been very forthcoming in publishing errata.
One of the things that has really puzzled me is that Philips have had such a "fight" getting the 932 to "behave" when all the other 89LPC chips have been well within "the industry standard" for bugs in new silicon. Anyhow, I believe (I have no such knowledge) that the 932A is the Philips guys giving up on the 932 base and making a 932 on the 93x base.

Anyhow one thing about the LPC series: You must follow the "kick into ISP/ICP" rules to the letter. For the chips with ISP capability I suggest you install the NoTouch for LPC9xx that you can find at the esacademy site, then you can kiss your worries godd-by.
