Need to find AT89S52 Programmer schematic diagram...

[chunei]

previously i did asked for help on finding the AT89C52 programmer but most of you guys said its programmer is not that reliable...

so i decide to change to AT89S52 and now I need to find and know how to construct the schematic diagram of the programmer 1st..

Hope someone can help.. thanks!!!

You better read this thread.

RS232 is the place you need to connect to the COM port.

Don't forget the ground connection on the 7805!
It's not on the schematic

Problem with that schematic is that you need to program one "AT89C" chip

it is not question of reliability-- you will be spending a lot in purchasing normal type programmer- while in system programming ( ISP ) possible in later version i.e., 89s52 and the type of programmer can be assembled by anyone, -i made one in just 20 minutes and used it. costs practically nothing. we don,t need ZIF etc unless the volume of work is too large-- ten ofcourse- you would have purchesd a ready made one.
for hobby and for vey small numbers, and dot-board assembled type will just serve.

see the one at www.ikalogic.com/isp.php
