'[EE] Small 8 pin micro from ST'

face picon face
Came across an advert in EDN this morning for an 8 pin micro from ST. Looks
to be quite an interesting beast, that would give the PIC 10F & 12F series a
run for its money.

ST7LITEUSx family

8 pin DIP, SO-8 or DFN package.
16 pin debug version available in small quantities.
8 x 8 bit unsigned multiply instruction
1k bytes flash program memory 10k write/erase cycles guaranteed
128 bytes RAM
5 bidirectional I/O
1 output only
11 interrupt vectors, 5 external interrupts available
10 bit ADC with up to 5 input channels
up to 8MHz internal RC clock, 3.3V to 5V Fcpu = 8MHz, 2.4V to 3.3V Fcpu =
4MHz

app notes and other technical stuff.

Larger pin no. members in the family as well.

Impressive. I wonder how expensive the prgramming tools are..

For companies....from the rep....usually free.  Most the time if the company has tools, they do that to get the silicon in the socket

That 0uA HALT power-down is hard to beat. And all those other
features too. I'd be tempted to try these

I agree. I studied the spec sheet for almost 2 hrs. I certainly have
applications for it.
And unlike many ST products in the past, somebody who actually KNOWS English
did the technical data sheet conversion from French to English.

Jinx, maybe James might want to run an "STList" as well...?

I'm still weighing up the developer options at Raisonance

http://www.raisonance.com/buy/prices.php#ST7

before I get a rush of blood and order anything. I've got plenty
of unfinished PIC business on the bench so ST7 would be a
spare-time sidetrack with an eye on future useage. Might have
a look and see what's on the local NZ market and also have a
nosey in the forums

ST seems not that hobbyist friendly and they are not as
popular as PIC/AVR/MSP430. I like US vendors more because
they have better documentations and development tools.

The forum is pretty empty. I think the ST forum is a better
place to go.
http://mcu.st.com/mcu/forums.html

I hear that ST MCUs have very good EMC performances
and they have a big presence in Singapore. Still I have
never tried any ST MCUs. Last time I was thinking of
using their STR7 ARM7 MCU. Now they have STM32
Cortex M3 ARM MCU. Both MCUs seem to be nice.

And they are a bit pig-headed, as well. I designed in their ST5760A
Video Text Generator
into almost every police car in the USA, and ST one day decided to drop
the device. No
amount of talk would dissuade them from dropping it. There was a market
for at LEAST
another 100K for pipeline robots as well as more police and motorcycle  
video systems, and
all this big brother surveillance coming on line, but nope, they dropped it.

Remarkable, to say the least.

Generate sufficient traffic and an [ST] tag will appear ...

But I did not see any prices, did I miss anything?
