Wait-a-second.  Please read the fine print on page ii of most
Microchip data sheets.

"Use of Microchip’s products as critical components in
life support systems is not authorized except with express
written approval by Microchip."

This means that Microchip has no liabity insurance for their
products to be used in this application.  Therefore your company
would be 100% responsible for any saftey issues.

Since the FDA regulates medical electronics in the USA, such a
device could almost certainly not be approved here. And if it
was, no hospital or doctor would likely be willing to use it.

That's my $0.02.

Andrew

Thank you very much for your opinions, I am reading each answer very
carefully.

At this poinmt I have one more question:

If Microchip sells devices like a PIC controller, and does not offer any
warranty for serious projects like an Incubator Controller for example ....
where can I find a secure device to use ?

Some years ago, I was the System4s Engineer Manager from a poultry company
here in Peru, and had developed a very simple incubator device using an
LM555 timer, a couple of thermo switches and a fan. The unit is working well
since 15 years ago with no fried eggs yet !!! .  Now my interest is to make
a more sophisticated device using a last technology components.

If Microchip does not offer any warranty in their products ...... maybe
Motorola will be a better option ?  I am familiar with the QY4 and JK3 HC08
Microcontroller series from Motorola, may any one in this list will tell me
some opinions ?

Regards,

Augusto, OA4CVT

Its not they offer no warranty, they just don't rate their products for
peoples lives. It sounds however like you want to make an incubator for
chicken eggs? whole other story, for that microchip would be more than happy
for you to use their products. And you wouldn't really need dual controllers
at all, simply test it well and be happy. Everybody here thought you were
making an incubator for a human baby where a minor failure would cause slow
and painful death. Baby chickens are called chicks.

So he wants to use PICs to get his chicks hot?
I've never seen THAT app note!

No! No! No!

What I want to develop is an Incubator for humans, for babys, got it ?
The story of my experience in poultry was only an example that I did years
ago with a couple of cheap components. Ok ?.
Excuse me if my english is poor !

Augusto

       I think you have misunderstood. It isn't that Microchip offers NO warranty
for those sorts of circumstances, it's that they don't BY DEFAULT allow you
to use their devices for things like that. Talk to them, see what they say,
it's very likely that they WILL support this sort of effect, for more money
of course. TTYL

It's not support/warranty, it's a legal issue. By putting in writing
that XXX company does not authorize the use of their components in life-
critical applications they hope to avoid being on the list of plaintiffs
if/when someone inevitably dies as the result of the failure of such a
product. They have relatively deep pockets.

You'll find the same disclaimers in just about every semi mfr's data.

National:
LIFE SUPPORT POLICY
NATIONAL'S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN
LIFE SUPPORT
DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT

Microchip:

is not authorized except with express written approval by Microchip.

semiconductor goods in such Critical Applications is understood to be fully

any other application in which the failure of the Motorola product could
create a situation

Motorola products for any such unintended or unauthorized application,
Buyer shall

affiliates, and distributors harmless against all claims, costs, damages,

and reasonable attorney fees arising out of, directly or indirectly, any
claim of personal injury or death associated with such unintended or
unauthorized use,
even if such claim alleges that Motorola was negligent regarding the design
or manufacture of the part.
