Hiya,

I've just partially read the data sheet and user guide for the DS89C450 and stumpled upon this builtin bootloader.
Do I understand it right that no programmer except for a standard Max232 and a serial lead is needed and that one can directly load Intel HEX files with any terminal software into the code memory?

If that is really the case than this should be the device of choice for students and hobbyists IMHO.

thanks,
Matthias
