I want to make a ckt which can we can forget after installing.
I am looking for cheap microcontroller one which we have stock is
89c2051 it is around 0.6$for single quantity. i am not interested in OTP. i want to program one by one.

I show a price of $1.60 each for 89C2051 from Mouser. The cheapest micro I know of is a PIC10F200I/P costing 53 cents in quantity one. Luhan P #### Paul Hovnanian P.E.

What are the development tools going to cost you?

(http://www.microchipdirect.com/) also sells the PIC10F200 for $0.49 in single unit quantity.

Maybe by OTP he meant mask-programmed.

Microchips developement software is free. A programmer can be build quite
easily. See:
http://www.oshonsoft.com/picprog.html
for one of the zillion possibilities.
Don't know whether the programming software for PIC10F200 is available
Last time I checked out it wasn't so I wrote my own software. Programming
specifications can be found on Microchips site.

building programmers and rewriting there own programming
software,yikes, why is everyone reinventing the wheel over and over and
over again, doesn't anyone reuse anything anymore, maybe I should join
the club and build a foundry and make my own chips

Maybe sellers of said programmers don't listen to what customers need and thus
they build it themselfes..

Hey, I made my own 8048 programmer years ago. Now I'm into PIC's and
made my own. Hell, its just another PIC project. My unit...

Uses the com port and communicates in 15200 baud serial.

Can take its 5 volts directly from the target device.

Makes its own 12 volts using an onboard voltage multiplier.

Has 4 status LED's that show power and programming status.

Can receive live debug output from the target while it is running.

Has an integrated simulator program.

Can be easily updated for new devices.

Also programs serial I2C eeproms.

Can be modified to accomodate future needs.

There are plenty of hobbyists who would rather assemble a $5 programmer (e.g., www.covingtoninnovations.com/noppp) than spend even$50 getting one
from the manufacturer.

Nice architecture, free development tools and cheap programmers (parallel &
USB IF).

development tools are one time charge not for life time

Some are, some have recurring licensing fees. Some may not survive the
What sort of production run to you have to spread the fixed costs over?
If its high, why isn't one-time programming an option? Keep the
additional unit cost of the cost of the programming step in mind here.
If field reprogrammability is an issue, then you will have to include
more tools (configuration control, upgrade distribution, etc). Embedded
s/w life cycles are significantly more involved than most people
realize.

quantiy is low in few hundreds its not a high volume project
I would like to say that programming and development tools are one time
investment and that is done at start of project thats it.

Thanks M.Randelzhofer thats it I was searching like these.
If some one knows such more controlles with less price like these the
suggesions are welcomed.
