#187828 - Crystal value and capacitor value for P89V51RD2 |
Hi,
I am using the schematic given in the below lonk to design my P89V51RD2 system. http://www.ece.ubc.ca/~jesusc/P89V51RD2_System.pdf I donot have 22MHz crystal as given in the schematic. I have 16MHz, 20.25MHz and 24MHz crystal. Which one can I use with P89V51RD2 ? I shall use RS232 for programming P89V51RD2. Is there a problem if I donot use 22MHz crystal? Will it affect baudrate? Another point is then, what will be the capacitor value to be used with 16MHz, 20.25MHz and 24MHz crystal, if I use them? Sincerely, Srinivas Nayak |
