Does anybody know if problems with the LPC2119/29 FullCAN hardware have
been fixed or when they will be fixed?
Does anybody know the extent of the problems?

Sounds like they plan to address all errata sheet items. I had to move six
product designs to ST parts because of the Rev A. errors.

This was my question, I was asking about the LPC2129:
(I was under the influence of too many part numbers...)

How have you found ST? I got badly burnt with ST on a number of ocassions... Admittedly quite a few years ago but I was thinking of using some of their stuff again... I do like the fact that Philips admit to the problems that they have. I have found quite a few companies, when I have had problems, have grudgingly admitted that they had known about the isses for a while...

Yes honesty in a manufacturer is paramount, let alone in any business
partner.

The product we're using is the STR712. Pretty decent peripheral software
libs, and a useful timing spreadsheet. The software libs offer a decent
head start, but it's not clear on the quality of test coverage. We're
running a protocol variation of SAE J1939, 16k of RAM for stack and
application is a bit too small for comfort, 32k is good, 64k offers a
feature upgrade path. Silicon errata, RAM size, pin compatibility, and
package options were the deciding factors. At the moment availability looks
very good.

Freescale has an interesting new offering, the MAC7100 series. But no clear
answer on production eta. It seems Freescale has taken the route of more
RAM like ST.
An interesting side note is the MAC7100 series came up with the smallest
code density on some quick IAR compilation tests. I've been meaning to drop
IAR an email about this.

The MAC7100 series looks interesting. My current interest is really in a
very small footprint device with USB so I think that the SAM7 will be
the go. In some respects it was a bit of a sad day that Motorola rolled
over and canned the 68K and went ARM. But then again it is nice not
having to replace all the devlopment tools every project! ;-)

Hello,

I think this is because MAC7100 are big endian, which has probably
less optimizer support than more common little endian arm7
controllers.

just started a MAC7100 specific group:

The MAC7111MPV40 is available from http://www.ebv.com. I had no problem
buying 2 even though on the web site they specify a minimum of 60.

I was looking at the MAC7141. Only a few MAC71X1 part numbers are currently
available. The ol' vaporware trick. Joel
