For a particular up, the manufacture specifies that the width of a certain control signal determined from the expression (T-50) where T is the clock period in ns. If we decide to use 5 MHz clock, what width should be expected for this control signal? The datasheet of the up specifies also that the data remain valid for another 20 ns after the end of this signal. What is the total duration of valid data presentation to memory? How many wait states should we insert if memory requires valid data presentation for at least 190 ns?
