New Atmel ATtiny Microcontrollers have 6 Pins, ADC, and LOW Power Consumption

These Atmel ATtiny microcontrollers have 6 pins, and an A/D. Draws a measly 100nA in 
sleep mode.

Article shows a useful pinout (what's the pinout on a 6-pin microcontroller?), a block 
diagram, and an interesting competitor analysis.

Pretty funky little device!

Funny how there isn't a 'price' row on that comparison table though.... 4 channel 8 bit ADC on a 6 pin part.... hmmm....

The counter capabilities with the multiple PWM modes are interesting. The details: http://atmel.com/dyn/products/product_card.asp?part_id=4558

Not in stock, but at least listed at Digikey, $0.50 each one for 25 units: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ATTINY10-TSHRCT-ND

This could be useful, because you can switch a pin from input to output at runtime. But using all 4 inputs all the time as ADCs makes only sense, if you want to generate some signals by changing power consumption, otherwise it would be a very autistic microcontroller :-) -- Frank Buss, fb@frank-buss.de http://www.frank-buss.de, http://www.it4-systems.de

Pity it doesn't have any EEprom.... but they are fantastic chips :)

I want a good brown-out monitor in a SOT23-6 chip for a manual reset switch, power-on reset, and brown-out detect function -- but right now must use 8-pin devices to get something semidecent with a micro. Unless someone knows of one? Jon

No debugWire :(

We use a MAX6324, with is a power supervisory chip with watchdog in an SOT23 package. If you don't want a watchdog you can get a similar device in a 4 pin package (SOT143). Andy

Not only that, but the in-system programming is almost completely useless. It requires 5V and three of the four IO pins. That means you need more space for protection resistors, power supply jumpers and other nonsense that you do for the microcontroller itself, in addition to the 6 pin programming connector. Basically, these devices are only useful if you can pre-program them before mounting. While that is not an unrealistic scenario for large volumes, a single wire programming interface that worked across the voltage range would have been much more useful.

As I wrote, "something .. with a micro." So, reliable BOR and POR plus 8-bit micro, possibly a little bit of E^2, 4 I/O or at least 3 I/O and 1 I, internal osc with say <= 2% accuracy over a 55C span centered on 25C, in SOT23-6. I add custom software to the functions. Jon

That was the first thing I looked for. The lack of debugWire will definitely rule it out for low volume, fast turnaround projects.
