To    PICLIST:

Quality, while unusual in this context, seemed like the word I wanted :-)

SUMMARY:    Has the 16F819 got any problems that would make
                          me think about not using it in a moderate volume
                          production application. ?

                         Comments sought from people who have used it.

DETAIL:

I'm about to design the next generation of a product.
Present product uses a non-PIC non-Flash processor.
I have several non-PIC candidate processors.
New processor will ideally be:

Bulletproof
Flash plus eerom parameter storage.
ISP
Hardware PWM (essential)
A/D - preferably 10 bit
Around 16 I/O
1K / 2K word versions preferable.
On board power on Reset and anti-Brownout that work
Available readily in Taiwan .
Reasonably priced basic development tools (basic programmer / simulator
probably adequate. ICE OK if cheap (as some are))

Low voltage operation a plus.
UART nice but not essential.

______________

Bullet proof translates to:

        Provided ALL data sheet operating specifications are met
        then NO unexpected operation modes, inexplicable crashes,
        weird startup modes or other bad surprises.

I have had too much of the above already from xxx's product.

I can tolerate known "features" which are well described and which can be
worked around (although these are better absent).

The 16F818 / 16F819 seems to meet my spec.
Notably 1K/2K Flash versions, hardware PWM, 10 bit A/D, ISP

So - has anyone got good or bad things to say about this particular PIC.
Any surprises.
Anyone used it in volume.
Brownout works OK in presence of Tesla coils and lightning ? :-)
Hand connect the battery and it starts every time?
etc
