hi,

i got interested with the ds89c420 uC because i found it easier to program based on the manuals/datahseets. however, i noticed that the 430/440/450 varieties are placed in a different category than the 420 (because of its iap capability).

now, is the hardware speficied in the "ultra-high-speed flash microcontroller user's guide" the same for the 430/440/450 uC's?

i had this doubt because the pdf filename is ds89c420_user_guide.pdf... ??? however if you try to look at page 130 of the pdf, it says "ultra-high-speed flash microcontroller"... ???

another issue would be, is the loader420 software capable of programming the 430/440/450 uC's?
