4 / 29 page DC Recommended Operating Ranges at Ta = 0 to +70°C Note: 2. All voltages are referenced to VSS. *: –2.0 V when pulse width is less than 20 ns. DC Electrical Characteristics at Ta = 0 to +70°C, VCC = 5 V ± 10% Note: 3. All current values are measured at minimum cycle rate. Since current flows immoderately, if cycle time is longer than shown here, current value becomes smaller. 4. ICC1 and ICC4 are dependent on output loads. Maximum values for ICC1 and ICC4 represent values with output open. 5. Address change is less than or equal to one time during RAS = VIL. Concerning ICC4, it is less than or equal to one time during 1 cycle (tPC). AC Electrical Characteristics at Ta = 0 to +70°C, VCC = 5 V ± 10% (Notes 6, 7 and 8) No. 5085-4/29 LC322271J, M, T-70/80 Parameter Symbol min typ max Unit Note Power supply voltage VCC 4.5 5.0 5.5 V 2 Input high level voltage VIH 2.4 6.5 V 2 Input low level voltage VIL –1.0* +0.8 V 2 (A0 to A7, A8R, RAS, CAS, UW, LW, OE) Input low level voltage (I/O1 to I/O16) VIL –0.5* +0.8 V 2 Parameter Symbol -70 -80 Unit Note min max min max Random read, write cycle time tRC 130 150 ns Read-write/read-modify-write cycle time tRWC 190 200 ns Fast page mode cycle time tPC 45 55 ns Fast page mode read-write/read-modify-write cycle time tPRWC 95 100 ns RAS access time tRAC 70 80 ns 9, 14, 15 CAS access time tCAC 20 30 ns 9, 14 Column address access time tAA 35 45 ns 9, 15 CAS precharge access time tCPA 40 50 ns 9 Output low-impedance time from CAS low tCLZ 0 0 ns 9 Output buffer turn-off delay time tOFF 0 20 0 20 ns 10 Rise, fall time tT 3 50 3 50 ns RAS precharge time tRP 50 60 ns RAS pulse width tRAS 70 10000 80 10000 ns RAS pulse width for fast page mode cycle only tRASP 70 100000 80 100000 ns Continued on next page.
