ROTFL :)

[..and I nearly said something about this in my other post, this 
morning.. !]

But yes, I am pleased to see something that has been talked about
for years, take a very good first step.

Nice parts. It says in the announcement that there is a 10bit ADC but in 
the LP2052/4052 datasheet there is only the comparator. If this refers 
to future devices, what would they cost?

 From a power consumption point of view it looks good, although not 
quite as good as an MSP430. What I do like is the fact that you can run 
it at 5V. That is pretty crucial when you have to drive FETs. That isn't 
so easy with the MSP series anymore.

A more complete family road map is at

and they have the 4 mode port pins, so you can do SW i2c, and CMOS FET ( 
or Piezo) drive, from the PWM mode if you wish...

Yes, but when you check the Atmel site for the parts with ADC it draws a 
blank. The press release, however, said "... announced today the 
availability of..." and "... The AT89LP family consists of devices with 
2 to 64 Kbytes of in-system programmable Flash memory, and is available 
in a variety of pin options, from 14, 20, 28 and 44. They include 
on-chip DataFlash®, 10-bit ADC,...".

To me, words like 'available' and 'consist of' means it's there. But it 
looks like they ain't.

Yes, OC is a wonderful thing. I believe the MSP430F2xxx series may have 
that, too. But those aren't out yet either.

What precludes even these low power '51 chips from many designs is their 
high idle power consumption, way too much for most battery based 
applications. You would need an external wake-up. Not that it can't be 
done, we actually did just that with ye olde Atmel 89C51, but it adds cost.

Not if they  were written by a French marketing assistant ...

When are these things going to be in the hands of the distys ?
Price (relative to a vanilla 2051/4051) ?
Pity no ADC or internal oscillator option.

Really dont know, knew about the core, but not the imminent release.

The word 'family' was used, so some members have ADC, some do not -
very like the P89LPC9xx series from Philips, or the Z8, etc.

Press release claims 85c/10K for 2K/20 pins and 99c/10K for 4K/20 pins,
which is under existing 89C4051 prices, and under the LPC92x, but
about on what I'd call the '2005 industry price curve' for uC pins/features.

uC are now cheaper than many generic alternatives :

The PCF8574 lists at $1.65/1K, so on a cents per I/O, the LP2052 looks
good.

The MAX3100 is $2.79/1K, which does SPI-UART bridge operation, and
a LP2052 can easily swallow that, and more..

The 14 pin and TSSOP packages make this a small solution for many 
'smarter IO expansion' problems.

With a buffered SPI port, at > 5MBd, that can be chained, many devices 
should be easily connected in series.
The LP2052 core can sustain 10MHz SPI in Master mode.

Not on the very first members, but On Chip CALOsc is a logical 'adder'

ROFL! But I wouldn't blame someone in France. They all play that game. 
After all, where is that 49 cents MSP430 device that TI says it has? 
AFAIK it ain't there, my distributor said that must have been for a mask 
part which they now discourage.

So, we all got hardened over time. Basically, if Digikey doesn't have 
stock or worse doesn't carry a part at all we try our utmost not to need 
that part in a design. Exceptions are very, very rare.
