Is there any difference in parrallel programming of at89c52 and 89s52,will a 89c52 programmer program a 89s52? AT89C52 needs a pulse on ALE/!PROG line of 1...110µsec length. AT89S52 on the other hand needs a puls lentgh of only 0.2...1µsec. That's a big difference! So, it must be expected, that AT89C52 programmer will probably produce a pulse that is too long for the AT89S52. But why toying arround with the parallel programmer? AT89S52 has a very nice ISP programming option! Kai |
