A start-up delay of 200 s 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 = 2 ns. 3. VIH (Min.) and VIL (Max.) are reference levels for measuring input timing signals. Transition times (tT) are measured between VIH and VIL. 4. This parameter is measured with a load circuit equivalent to 2 TTL loads and 100 pF. 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 achieves 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 edge in an early write cycle, and to the WE leading edge in an OE control write cycle, or a read modify write cycle. 12. The test mode is initiated by performing a WE and CAS before RAS refresh cycle. This mode is latched and remains in effect until the exit cycle is generated. The test mode specified in this data sheet is a 2-bit parallel test function. CA9 is not used. In a read cycle, if all internal bits are equal, the DQ pin will indicate a high level. If any internal bits are not equal, the DQ pin will indicate a low level. The test mode is cleared and the memory device returned to its normal operating state by performing a RAS-only refresh cycle or a CAS before RAS refresh cycle. 13. In a test mode read cycle, the value of access time parameters is delayed for 5 ns for the specified value. These parameters should be specified in test mode cycle by adding the above value to the specified value in this data sheet. 8/17 E2G0100-17-41M Semiconductor MSM5117805C ,,, , ,, , ,,,, TIMING WAVEFORM Read Cycle tRC tRAS tRP RAS VIH - VIL - tCRP tCSH tCRP tRCD VIH - CAS VIL - VIH - VIL - VIH - VIL - VIH - VIL - VOH - tRAD tRSH tCAS tRAL tASR tRAH tASC tCAH Address Row Column tRCS tRRH tRCH WE tAA tROH tOEA tREZ OE tRAC tCAC tOEZ tCEZ DQ VOL - Open Valid Data-out tCLZ "H" or "L" Write Cycle (Early Write) tRC tRAS tRP RAS VIH - VIL - tCRP tCRP tCSH tRCD tRSH VIH - CAS VIL - VIH - VIL - VIH - VIL - tRAD tRAH tCAS tASR tASC tCAH tRAL Address Row Column tWCS WE tWCH tWP tCWL tRWL OE VIH - VIL - VIH - tDS tDH DQ VIL - Valid Data-in Open "H" or "L" 9/17 ,,, Semiconductor MSM5117805C Read Modify Write Cycle tRWC tRAS tRP VIH - RAS VIL - tCSH tCRP tCRP tRCD tRSH CAS VIH - VIL - tCAS tASR tRAH tASC tCAH VIH - Address VIL - VIH - VIL - VIH - VIL - VI/OH- Row Column tRAD tRWD tCWD WE OE tAA tAWD tCWL tRWL tWP tRCS tOEA tOED tOEH tCAC tRAC tOEZ tDS tDH DQ VI/OL- tCLZ Valid Data-out Valid Data-in "H" or "L" 10/17 Semiconductor Fast Page Mode Read Cycle (Part-1) Address Fast Page Mode Read Cycle (Part-2) Address , ,,, , , MSM5117805C tRASP tRP RAS VIH - VIL - tRHCP tCRP tRCD tHPC tCP tCP CAS VIH - VIL - tCAS tCAS tCAS tRAD tASR tRAH tASC tCSH tCAH tASC tCAH tASC tCAH VIH - VIL - VIH - VIL - VIH - VIL - Row Column Column Column tRCS tRRH WE tCHO tOCH tRAC tAA tOEP OE tAA tAA tOEP tOEA tCAC tCPA tDOH tCAC tOEA tOEA tOEZ tCAC tOEZ tREZ DQ VOH - VOL - tCLZ Valid Data-out Valid Data-out Valid* Data-out Valid* Data-out * : Same Data, "H" or "L" tRASP tRP RAS VIH - VIL - tRHCP tCRP tCRP tHPC tRCD tCP tCP CAS VIH - VIL - tCAS tCAS tCAS tRAD tASR tRAH tCSH tASC tCAH Column tASC tCAH tASC tCAH VIH - VIL - VIH - VIL - VIH - VIL - Row Column Column tRCS tRCS WE tRAC tAA tRCH tWPE tAA tAA OE tCPA tOEA tCAC tWEZ tCAC tCAC tDOH tCEZ DQ VOH - VOL - tCLZ Valid Data-out Valid Data-out Valid Data-out "H" or "L" 11/17 ,, , , , Semiconductor MSM5117805C Fast Page Mode Write Cycle (Early Write) VIH - VIL - tRASP tRP RAS tCRP tRCD tHPC tHPC tCP tCP CAS VIH - VIL - tCAS tCAS tCAS tRAD tASR tRAH tCSH tASC tCAH Column tASC tCAH tASC tRSH tCAH Address VIH - VIL - VIH - VIL - VIH - VIL - VIH - VIL - Row Column Column tWCS tWCH tWCS tWCH tWCS tWCH WE OE tDS tDH tDS tDH tDS tDH DQ Valid Data-in Valid Data-in Valid Data-in "H" or "L" Fast Page Mode Read Modify Write Cycle tRASP RAS VIH - VIL - tRWD tCRP tRCD tCP CAS VIH - VIL - tRAD tCWD tASR tRAH tASC tHPRWC tCPWD tASC tCAH tCWL tCPA tCAH tRWL Address VIH - VIL - Row Column Column tRCS tAWD tRCS tCWD WE VIH - VIL - tRAC tAWD tAA tDS tWP tAA tDS tWP OE VIH - VIL - tOEA tOED tOEH tDH tOEA tOED tOEH tDH tCAC tOEZ tCAC tOEZ DQ VI/OH - VI/OL - Valid Data-out Valid Data-in Valid Data-out Valid Data-in tCLZ tCLZ "H" or "L" 12/17 Semiconductor RAS-Only Refresh Cycle t RC tRAS RAS V IH - V IL - tCRP CAS V IH - V IL - tASR Address V IH - V IL - tCEZ DQ V OH - V OL - Open Row tRAH tRPC MSM5117805C tRP Note: WE, OE = "H" or "L" "H" or "L" CAS before RAS Refresh Cycle tRC t RP RAS VIH - VIL - tRPC tCP CAS VIH - VIL - tWRP WE VIH - VIL - t CEZ DQ VOH - VOL - Open Note: OE, Address = "H" or "L" "H" or "L" tWRH tWRP tCSR tCHR tRAS t RPC tRP 13/17 Semiconductor Hidden Refresh Read Cycle ,,, ,, ,, , MSM5117805C tRC tRAS tRP tRC tRAS tRP RAS VIH - VIL - VIH - VIL - VIH - VIL - VIH - VIL - tCRP tRCD tRSH tCHR CAS tASR tRAH tRAD tASC tCAH Address Row Column tRCS tRAL tRRH WE tAA tROH OE VIH - VIL - tOEA tRAC tCAC tCLZ tCEZ tOEZ tREZ DQ VOH - VOL - Open Valid Data-out "H" or "L" Hidden Refresh Write Cycle tRC tRAS tRP tRC tRAS tRP RAS VIH - VIL - VIH - VIL - tCRP tRCD tRSH tCHR CAS tASR tRAH tRAD tASC tCAH tRAL Address VIH - VIL - VIH - VIL - VIH - VIL - VIH - VIL - Row Column tWCS tRWL tWCH WE tWP OE tDS tDH DQ Valid Data-in "H" or "L" 14/17 Semiconductor Test Mode Initiate Cycle RAS CAS WE DQ , MSM5117805C tRC tRP tRAS VIH - VIL - tRPC tCP tCSR tCHR VIH - VIL - tWTS tWTH VIH - VIL - tOFF VOH - VOL - Open Note: OE, Address = "H" or "L" "H" or "L" 15/17 Semiconductor MSM5117805C PACKAGE DIMENSIONS (Unit : mm) SOJ28-P-400-1.27 Mirror finish Package material Lead frame material Pin treatment Solder plate thickness Package weight (g) Epoxy resin 42 alloy Solder plating 5 mm or more 1.30 TYP.
