So, what's your estimate of the total number of JT-designed ICs that
have ever been produced? I mean actual individual chips, not designs.

Jim said:I wouldn't know where to begin.
Probably the 1488/1489 RS-232 chip set would have had the highest
volume.
Although my alternator regulator chips would be up in the millions
also.
The PLL stuff would be high volume but not astronomic.
Then I have probably 100 custom chips, designed for
application-specific use, probably each in the 10K/year category.
But this latest one for SC Johnson will probably be an all-time
high... only way the volume could be any better would be if it fit
into a TP dispenser ;-)
BTW: This design runs off a single cell, boosts its own VDD, and has
also a HV output to drive a piezo actuator that drives the pump. Also
counts the time between "squirts" ;-)

I suppose this is going to be even more volume than those cheezy $5.00
calculators -- but how about $1.98 wristwatches?
Which PLL stuff did you design, and are there any useful Motorola (sorry
-- freonscale) chips that you _haven't_ designed?
Hey, Here's my latest gadget:

Actually, three of us here worked on this for about three years as
sort of a background project, when we didn't have a paying customer
screaming for delivery on something. I never appreciated how much
hassle a benchtop instrument would really be until this got serious. A
VME or PCI board is blindingly simple compared to all the stuff you
have to put into a box like this. And by the time you finish it,
things have changed so much you're dying to redesign it again from
scratch. m.u.s.t..r.e.s.i.s.t..t.e.m.p.t.a.t.i.o.n.

I read in sci.electronics.design that Jim Thompson
4ax.com>) about 'One of My High Technology Contributions to Microchip
Design', on Fri, 16 Jul 2004:
Have you got versions for elderly electronic engineers that emit 'sawing
Ebonite', 'hot Paxolin' and 'selenium dioxide'? (;-)
must be one of those obscure definitions of "contribution"
with which I am not familiar.
Jim said:I laid myself off in 1970, so anything after that is someone else's
work.... although there's really nothing new, just process
improvements on designs by Ron Treadway and myself.

...Jim ThompsonROTFLMAO! That's a constant problem with circuit designers... when to
let it loose and call it completed... I'm always in a quandary with
"perfection" ;-)

I don't know what ROTFLMAO stands for, but an old engineer once
said to me "Shoot the engineer, deliver the product".
