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.

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.

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