QUESTION(s):

Reply by pvt email may be best unless of special interest to list.
Also, I'm on PIClist digest now so a direct email will reach me
faster.
I could summarise & post info if several useful replies received.


1.    Has anyone got reasonable information on the price of bottom
end PICs in say 1000 and 20000 quantities. Candidates would be
12C508, 508A, 509, 509A, 16C54, 16C56 AND any of the newer variants
with similar functionality and cost.

2.    Also - if there is any known PIC which is similarly priced but
functionally much more capable in these quantities. eg is there
anything with a 14 bit core that can compete on price. eg 554, 556
etc

Potential targets seem to be:
12C-       508, 509, 681
16C        54, 56, 622, 826 (exists?)
16F        ??? (probably too dear)

I've sought this information via the Microchp website, email to
Microchip and discussions with a local supplier.
Without going into boring detail - I need more information than I've
got so far.

BACKGROUND:

I've been asked to consider picking up an existing PIC development
project at short notice.
I need information before a meeting on Monday 10am (NZ time)

I'm looking for comparative pricing for bottom end PICs in moderate
to large quantities.

If it works out (and it should) annual volumes should initially be
around 20,000 per annum and could be very much more than this if it
really took off.

This is yet another multi-drop network system but with a very special
difference - can't give details yet but probably will be able to in
due course.
The system has 2 main components - one is very cost sensitive and
probably has a finished cost of around $US12 so processor cost must
be minimal.

The prototypes to date use a 12C508. I haven't seen code yet but I
understand that more ROM is probably going to be needed and also
possibly more I/O. 12 bit core will probably be adequate.

More pins COULD be provided by serial I/O if going from an 8 pin to
18 pin PIC is not costs effective.

Summary of prices I have so far (using $US1 = $NZ2 which is about
right)
This actually puts the $US price slightly too low.

16C56    $US1.70/1000s        Must be able to be less than this !!!
16C622   $US2.00/10,000s
12C508   $US1.60ish / 100,000s
12C508A  $US1.55ish/10,000s
12C509A  $US1.50ish / 1000s

The surprises to me here are the lower cost of 12C509A compared with
12C508 and the high cost of eg 16C56.

Does anyone have better figures?



TIA
