A start-up delay of 200µs is required after power-up, followed by a minimum of eight initialization cycles (RAS-only refresh or CAS before RAS refresh) before proper device operation is achieved. 2. The AC characteristics assume tT = 5ns. 3. VIH (Min.) and VIL (Max.) are reference levels for measuring input timing signals. Transition times (tT) are measured between VIH and VIL. 4. -50 is measured with a load circuit equivalent to 2 TTL load and 50pF, and -60/-70 is measured with a load circuit equivalent to 2 TTL load and 100pF. 5. Operation within the tRCD (Max.) limit ensures that tRAC (Max.) can be met. tRCD (Max.) is specified as a reference point only. If tRCD is greater than the specified tRCD (Max.) limit, then the access time is controlled by tCAC. 6. Operation within the tRAD (Max.) limit ensures that tRAC (Max.) can be met. tRAD (Max.) is specified as a reference point only. If tRAD is greater than the specified tRAD (Max.) limit, then the access time is controlled by tAA. 7. tOFF (Max.) and tOEZ (Max.) define the time at which the output achieved the open circuit condition and are not referenced to output voltage levels. 8. tRCH or tRRH must be satisfied for a read cycle. 9. tWCS, tCWD, tRWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS ≥ tWCS (Min.), then the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle. If tCWD ≥ tCWD (Min.), tRWD ≥ tRWD(Min.), tAWD ≥ tAWD (Min.) and tCPWD ≥ tCPWD (Min.), then the cycle is a read modify write cycle and data out will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, then the condition of the data out (at access time) is indeterminate. 10. These parameters are referenced to the UCAS and LCAS, leading edges in an early write cycle, and to the WE leading edge in an OE control write cycle, or a read modify write cycle. 11. These parameters are determined by the falling edge of either UCAS or LCAS, whichever is earlier. 12. These parameters are determined by the rising edge of either UCAS or LCAS, whichever is later. 13. tCWL should be satisfied by both UCAS and LCAS. 14. tCP is determined by the time both UCAS and LCAS are high. 8/15 FEDD5116160F-02 1Semiconductor MSM5116160F TIMING CHART Read Cycle RAS tRC tRAS VIH tRP VIL tCSH tCRP CAS WE tCRP tRSH tCAS VIH tRAD VIL tRAL tASR Address tRCD VIH VIL tRAH tASC Row tCAH Column tRRH tRCS VIH tAA VIL tRCH tROH tOEA OE VIH VIL tCAC tRAC DQ tOFF tOEZ tCLZ VOH Valid Data-out Open VOL “H” or “L” Write Cycle (Early Write) RAS tRC tRAS VIH tRP VIL tCSH tCRP CAS tRAD VIL tRAL VIH VIL tRAH tASC Row tCAH Column tCWL tWCS tWP WE OE DQ tCRP tRSH tCAS VIH tASR Address tRCD tWCH VIH VIL tRWL VIH VIL VIH VIL tDS tD Valid Data-in Open “H” or “L” 9/15 FEDD5116160F-02 1Semiconductor MSM5116160F Read Modify Write Cycle tRWC tRAS RAS VIH tRP VIL tCSH tCRP CAS tRAD VIL VIH VIL tCRP tRSH tCAS VIH tASR Address tRCD tRAH tASC Row tCWL tRWL tCAH Colum tRCS tCWD tWP tRWD WE OE VIH VIL tAWD tAA tOEH tOE VIH tOED VIL tCAC tDH tRAC DQ VI/OH VI/OL tOEZ tCLZ Valid Data-out tDS Valid Data-in “H” or “L” 10/15 FEDD5116160F-02 1Semiconductor MSM5116160F Fast Page Mode Read Cycle tRASP RAS VIH VIL tRCD tCRP CAS tCP tCP tRAD tCSH VIL VIH VIL Row tASC tCAH Column tCAH tASC Column tRCH tCAH Column tRCS tRCH tRCS tRCH VIH VIL tAA tAA tAA tOEA tRRH tOEA VIH VIL tCPA tOFF tOEZ tRAC tCAC DQ tCRP tRAL tRAH tASC tOEA OE tRSH tCAS tCAS VIH tRCS WE tRHCP tCAS tASR Address tRP tPC tOEZ Valid Data-out Valid Data-out VOL tOFF tCAC tOEZ t CLZ tCLZ tCLZ VOH tCPA tOFF tCAC Valid Data-out “H” or “L” Fast Page Mode Write Cycle (Early Write) tRP tRASP RAS VIH VIL tCRP tCP tRCD tCP tCAS CAS tCAS VIH VIH VIL tRAH tASC Row tCSH tCAH tASC Column tCRP tASC tRAL tCAH Column tRWL tWCS tWCH tWP tCWL tWCS VIH tWCH tWP tCWL tWCS tWP tWCH VIL tDS VIH DQ tCAH Column tCWL WE tRSH tCAS tRAD VIL tASR Address tRHPC tPC VIL tDH Valid * Data-in tDS tDH Valid * Data-in tDS tDH Valid * Data-in Note: OE = “H” or “L” “H” or “L” 11/15 FEDD5116160F-02 1Semiconductor MSM5116160F Fast Page Mode Read Modify Write Cycle tRASP tCSH tPRWC tRP tRSH VIH RAS VIL tRCD tCP tCAS tRAH tASR VIH VIL tCAH tRAD VIL Address tCR tCAS tCAH VIH CAS tCP tCAS tCAH tCWL tASC Row tASC Column Column tRCS tPWD tCWD tRCS tASC tRAL tCWL Column tRCS tCPWD tCWL tCPWD tCWD tCWD tAWD tAWD tRWL VIH WE tAWD VIL tWP tRAC tAA tDH tOEA VIH OE tCAC tAA VI/OL Out tCLZ tCAC tDS tOED tOEZ tDS tCAC Out In tDH tOEA tOED tOEZ tOEZ VI/OH DQ tCPA tOEA tOED VIL tROH tDH tAA tDS tWP tWP tCPA In Out In tCLZ tCLZ Note: In = Valid Data-in, Out = Valid Data-out “H” or “L” RAS-only Refresh Cycle tRC tRAS RAS VIH tRP VIL tCRP CAS Address DQ tRPC VIH VIL VIH VIL VOH VOL tASR tRA Row tOFF Open Note: WE, OE = “H” or “L” “H” or “L” 12/15 FEDD5116160F-02 1Semiconductor MSM5116160F CAS before RAS Refresh Cycle tRC tRP RAS tRAS VIH VIL tRPC tCP tRP tCSR tRPC tCHR CAS VIH VIL tOFF DQ VOH Open VOL Note: WE, OE, Address = “H” or “L” “H” or “L” Hidden Refresh Read Cycle tRC RAS VIH VIL tRC tRAS tRAS tCRP tRCD tRSH tRP tRP tCHR CAS VIH tRAD VIL tASR Address VIH VIL tRAH tASC tCAH Column Row tRCS WE tCAC tRRH VIH tRAL VIL tAA tROH OE DQ VIH VIL VOH VOL tOFF tOEA tRAC tOEZ tCLZ Open Valid Data-out “H” or “L” 13/15 FEDD5116160F-02 1Semiconductor MSM5116160F Hidden Refresh Write Cycle tRC tRC tRAS RAS tRAS VIH VIL tCRP tRSH tRCD tRP tRP tCHR CAS VIH tRAD VIL tASR Address VIH VIL tRA tRAL tASC Row tCAH Column tWCS WE OE DQ tWCH VIH VIL tWP VIH VIL VIH VIL tDS tDH Valid Data-in “H” or “L” 14/15 FEDD5116160F-02 1Semiconductor MSM5116160F NOTICE 1.
