tAH, tDSWW, tAS1, tAS2, and tACC depend on tcyc as shown below.
(1) VCC = 5.0 V ±10% (S-mask)
tAH
= 0.5 × tcyc – 26 (ns)
tDSWW = 1.5 × tcyc – 24 (ns)
tAS1 = 0.5 × tcyc – 21 (ns)
tAS2 = tcyc – 32 (ns)
tACC = 2.5 × tcyc – 56 (ns)
(2) VCC = 3.0 V (S-mask)
tAH
= 0.5 × tcyc – 40 (ns)
tDSWW = 1.5 × tcyc – 30 (ns)
tAS1 = 0.5 × tcyc – 35 (ns)
tAS2 = tcyc – 35 (ns)
tACC = 2.5 × tcyc – 90 (ns)
(3) VCC = 2.7 V (S-mask)
tAH
= 0.5 × tcyc – 42 (ns)
tDSWW = 1.5 × tcyc – 37 (ns)
tAS1 = 0.5 × tcyc – 42 (ns)
tAS2 = tcyc – 45 (ns)
tACC = 2.5 × tcyc – 122 (ns)
