Hello Ulf,> Read All About it, Read all About it. > > Atmel releases single clock cycle 8051 chips... > http://www.atmel.com/dyn/corporate/view_detail.asp?FileName=AT89LP_3_8.htmlNice 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. Regards, Joerg http://www.analogconsultants.com

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.

But it looks like they ain't.>> 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.

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. Regards, Joerg http://www.analogconsultants.com

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.> Pity no ADC or internal oscillator option.Not on the very first members, but On Chip CALOsc is a logical 'adder' -jg

Hello Ulf,>>To me, words like 'available' and 'consist of' means it's there. > > Not if they were written by a French marketing assistant ...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.
