NOTES:
1) tRC (read cycle time) = 160 ns maximum
2) tRAC (access time from RAS) = 80 ns maximum
3) tRP (RAS precharge time) = 80 ns maximum
4) tCAS (CAS pulse width) = 25 ns maximum
5) tCP (CAS precharge in Page mode = 25 ns maximum
6) tPC (Page mode cycle time) = 50 ns minimum at maximum
7) Word reads shown, for byte reads only one of CAS[3:0] is active, CAS0 for byte 0, etc.
