Hii all, I am looking for Atmel89c52 bootloader so that i can do in-system programming. I searched the net, but could not find any site regarding this. Any help will be appreciated. Thanks, Sharaf

You can't in-system program an 89C52. It needs an external parallel programmer.

IIRC, Atmel had a schematic showing how it (ISP, not a bootloader) could be done- but it was WAY more trouble than it was worth.

Its successor, 89S52, has ISP capability (using a few port pins for SPI). The software is free for download, the cable consists of a single buffer IC and a few passives.

But the 89C51RD2 (Atmel or Philips) is ISP and superior to the 89C52

The request for a boot loader sounded like he was wanting it to program itself. Even the 89S52 can't do that.
The AT89C51RD2 can reprogram itself and is pin compatible with 89C52. It has a built in boot loader which allows you to program it directly from a PC serial port. (with a max232 or something)

I know. We are using both types in current products and developments. :-)
I simply overlooked the "bootloader" when answering your statement mentioning the need of parallel programming.
