#187829 - any, choose the one that
Responding to: ???'s previous message
Which one can I use with P89V51RD2 ?
any, choose the one that gives the closest match to your baudrate

I shall use RS232 for programming P89V51RD2. Is there a problem if I donot use 22MHz crystal? Will it affect baudrate?
no

Another point is then, what will be the capacitor value to be used with 16MHz, 20.25MHz and 24MHz crystal, if I use them?
same

Erik

PS DO NOT believe "a wire is a wire" these components must be VERY close to the associeted pins.
