Hi everyone,
I am new to the board design and stuff so please excuse me for asking
questions that may be selfevident... ;-) What I want to do is to connect
an
Intel StrataFlash (or compatible) linear flash memory device (8MB) to an
Intel PXA26x processor. Now I wonder if I should pay attention to the
impedance (some time ago I heard a weird fairy tale saying that everything
on board should be designed to 50 Ohms...?!) on the lines that connect the
devices or just design some connections no matter how and let a matter
rest.
What I really want to know is not only "yes" or "no" or "doesn't matter",
but a sophisticated statement that explains to me why it is that way or
the
other and when the impedance does matter?
Hope anyone can help me out of this misery. Thank you in advance for any
helpful advice.
Norman
