I don't know the answer for sure, but most likely its OK.

But if I were doing a new design, I'd use a newer part. The LPC11xx series
parts are equivalent in performance, and don't require either an external
resonator (you can use a crystal to get a more accurate clock) or a 1.8V
regulator. And they are cheaper. If you need some more performance or a couple
UARTs, the LPC1751 is another good choice (the PROplus part)

We'll be rolling out the XB sensor and a new PRO family member when parts become
available in the TSSOP-28 package

Bruce - any chance we can buy pre-programmed TSSOP or even DIP modules?

The part we will be using is announced here, hopefully they will be available
soon as its not new silicon, just a new package.

You use to be able to buy pre-programmed parts through distribution, I assume
that's still available, but its was never free unless you were doing huge
volumes.

As for DIP modules, we won't be doing any unless we see some volume. Just from
internet searches we see, it looks to us like the Parallax Stamp business is
dead, and the Arduino form factor generates 8-10x more hits.

Over the last 2+ yrs I've used some Coridium Pros, and a larger number of PICAXE
dips and have become very familiar with each, and written quite a lot of code.

IMHO - The PICAXE is a fine product for $4, BUT it is an interpreter running
typically 200-500 times slower than the PRO, and has a rather limited, somewhat
quirky BASIC. I would expect a competitively priced DIP with compiled Basic, 32
bit integers, arrays and parentheses to control order of execution, to generate
a fair bit of interest in this market. And a significant number of users make
their own boards w/SMD.

I'm not a fan of the Arduino form factor, nor am I ready to buy a commercial
license to program my own chips with ARMbasic. Maybe we could buy some dips when
available and ship them to you for programming?

Watching future announcements with interest.

Since this message, NXP added a DIP28 version which is now shipping as the BASICchip

As of this writing (Jan 2013) an SO20 version of the LPC812 will be available in a couple months and we will make that a product.

In the meantime we have received some 80 of the TSSOP20 versions of the LPC812 and will be building those into breakout boards for alpha testing next month.
