A start-up delay of 200s 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 = 2ns. 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 1 TTL load and 50pF, and -60/-70 is measured with a load circuit equivalent to 1 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. tCEZ (Max.), tREZ (Max.), tWEZ (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. tCEZ, and tREZ must be satisfied for open circuit condition. 9. tRCH or tRRH must be satisfied for a read cycle. 10. 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. 11. These parameters are referenced to the CAS, 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. 9/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F TIMING CHART Read Cycle RAS VIH VIL tCRP CAS VIH VIL tASR Address VIH VIL VIH VIL VIH VIL tRAC DQ VOH VOL tCLZ Open Valid Data-out "H" or "L" tCAC tOEZ tCEZ tAA tROH tOEA OE tRCH tREZ tRAD tRAL tRAH tASC Column tRCS tCAH tRCD tRP tCSH tRSH tCAS tCRP tRC tRAS Row tRRH WE Write Cycle (Early Write) tRC tRAS RAS VIH VIL tCRP CAS VIH VIL tASR Address VIH VIL tRAD tRAL tRAH tASC tCAH tRCD tRP tCSH tRSH tCAS tCRP Row tWCS Column tCWL tWCH tWP tRWL WE VIH VIL VIH VIL tDS VIH VIL OE tDH Valid Data-in Open "H" or "L" DQ 10/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F Read Modify Write Cycle tRWC tRAS RAS VIH VIL tCRP CAS VIH VIL tASR Address VIH VIL tRAD tRAH tASC tCAH tCWL tRWL tRCD tRP tCSH tRSH tCAS tCRP Row Column tRCS tRWD tCWD tWP tAWD tAA tOEA tOED tCAC tRAC tOEZ tCLZ Valid Data-out WE VIH VIL VIH VIL tOEH OE tDH tDS Valid Data-in DQ VI/OH VI/OL "H" or "L" 11/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F Fast Page Mode Read Cycle (Part-1) tRASP tRCD RAS VIH VIL tCRP CAS VIH VIL VIH VIL VIH VIL VIH VIL tOEA tCAC DQ VOH VOL tCLZ * : Same Data, "H" or "L" tAA tRAC tAA tCPA tDOH Valid Data-out tOEZ Valid Data-out tRP tHPC tRHCP tCP tCAS tCAS tASC tCAH tCSH tCAS tRAD tASR Row tRCS tRAH tASC tCAH tCP tASC Column tCAH Address Column Column tOCH tCHO tOEP tCAC tAA tRRH WE tCAC tOEP tOEA OE tOEA tOEZ Valid * Data-out tREZ Valid * Data-out Fast Page Mode Read Cycle (Part-2) tRASP tHPC RAS VIH VIL tCRP tCSH tRCD tCAS tRAD tASR Row tRCS WE VIH VIL VIH VIL tCAC tCAC DQ VOH VOL tCLZ "H" or "L" tWEZ Valid Data-out tRP tRHCP tHPC tCRP tCP tCAS tCAH Column tASC Column tCAS tCP CAS VIH VIL VIH VIL tRAH tASC tCAH tASC tCAH Address Column tRCS tAA tRAC tRCH tWPE tOEA tAA tCPA tAA OE tCAC tDOH Valid Data-out tCEZ Valid Data-out 12/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F Fast Page Mode Write Cycle (Early Write) tRASP tCSH RAS VIH VIL VIH VIL VIH VIL VIH VIL VIH VIL tDS DQ VIH VIL Valid Data-in tRP tHPC tHPC tCP tCAS tRSH tCAS tCAH tCRP tRCD tCAS tRAD tCP CAS tASR Row tRAH tASC tCAH tASC tCAH tASC Address Column tWCS tWCH Column tWCS tWCH Column tWCS tWCH WE OE tDH tDS Valid Data-in tDH tDS Valid Data-in tDH "H" or "L" Fast Page Mode Read Modify Write Cycle tRASP tRWD RAS VIH VIL VIH VIL tASR Address VIH VIL VIH VIL tRAC tOEA OE VIH VIL tCAC DQ VI/OH VI/OL tCLZ tOEZ Valid Data-out tCPWD tCP tCWD tASC tHPRWC tCAH tCWL Column tRCS tAWD tCWD tAWD tDS tWP tAA tOEA tOED tDH Valid Data-in tCRP tRCD tRWL CAS tASC tRAD tRAH Column tRCS tCAH tCPA Row WE tAA tDS tWP tOEH tCAC tOEZ tOED tOEH tDH Valid Data-in Valid Data-out tCLZ "H" or "L" 13/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F RAS-only Refresh Cycle tRC RAS VIH VIL VIH VIL VIH VIL VOH VOL tASR tRAH tCRP tRAS tRP tRPC CAS Address Row tCEZ DQ Open Note: WE, OE = "H" or "L" "H" or "L" CAS before RAS Refresh Cycle tRP RAS VIH VIL VIH VIL VIH VIL tCEZ DQ VOH VOL Open Note: OE, Address = "H" or "L" "H" or "L" tWRP tWRH tWRP tRPC tCP tCSR tCHR CAS tRAS tRP tRPC tRC WE 14/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F Hidden Refresh Read Cycle tRC tRAS RAS VIH VIL VIH VIL tASR Address VIH VIL VIH VIL tRAD tRAH Row tRCS WE tASC Column tCAC tRAL tAA tROH OE VIH VIL VOH VOL tRAC tCLZ Open Valid Data-out "H" or "L" tOEA tOEZ tWRP tWRH tCEZ tREZ tRRH tCAH tCRP tRCD tRSH tRP tCHR CAS tRP tRAS tRC DQ Hidden Refresh Write Cycle tRC tRAS RAS VIH VIL VIH VIL tASR Address VIH VIL tRAD tRAH Row tASC tCAH Column tRAL tRWL tWP WE VIH VIL tWCS OE VIH VIL VIH VIL "H" or "L" tDS tDH Valid Data-in tWCH tWRP tWRH tCRP tRCD tRSH tRP tCHR CAS tRP tRAS tRC DQ 15/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F REVISION HISTORY Document No. FEDD51V17805F-01 FEDD51V17805F-02 Date Dec, 2000 Aug, 2002 Page Previous Current Edition Edition - 1, 2 - 1, 2 Final edition 1 Description Deleted SOJ package 16/17 FEDD51V17805F-02 1 Semiconductor MSM51V17805F NOTICE 1.
