Clock Waveforms
Valid in normal clock mode. In X2 mode XTAL2 must be changed to XTAL2/2.
This diagram indicates when signals are clocked internally. The time it takes the signals to propagate to the pins, however,
ranges from 25 to 125 ns. This propagation delay is dependent on variables such as temperature and pin loading. Propaga-
tion also varies from output to output and component. Typically though (T
A
=25
°
C fully loaded) RD and WR propagation
delays are approximately 50ns. The other signals are typically 85 ns. Propagation delays are incorporated in the AC
specifications.
