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. When using the internal refresh counter, a minimum of eight CAS before RAS initialization cycles is required. 2. AC mesurement assume tT = 5 ns. 3. VIH (Min.) and VIL (Max.) are reference levels for measuring input timing signals. Transition times are measured between VIH and VIL. 4. 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, 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, access time is controlled by tAA. 7. tOFF (Max.) defines the time at which the output achieves an open circuit condition and is not referenced to output voltage levels. 8. tRCH or tRRH must be satisfied for a read cycle. 9. 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 an 8-bit parallel test function. RA10, CA10 and CA0 are not used. In a read cycle, if all internal bits are equal, the data output pin will indicate a high level. If any internal bits are not equal, then data output pin will indicate a low level. The test mode is cleared and the memory device returned to its normal operational state by performing a RAS-only refresh cycle or a CAS before RAS refresh cycle. 10. In a test mode read cycle, the access time parameters are delayed by 5 ns. The test mode parameters are obtained by adding 5 ns to the normal read cycle values. 8/13 Semiconductor MSC23409C/CL-xxDS9 TIMING WAVEFORM Read Cycle tRC tRP tRAS VIH - RAS V - IL tCSH tCRP tRCD CAS VIH - CAS8 VIL - tCRP tRSH tCAS , , , ,, , tRAD tASR Address VIH - VIL - tRAH tRAL tCAH tASC Row Column tAR tRRH tRCS WE VIH - VIL - tRCH tCAC tAA DQ0-7 VOH - Q8 VOL - tOFF tCLZ tRAC Open Valid Data-out "H" or "L" Write Cycle (Early Write) tRC tCSH tCRP tRCD CAS VIH - CAS8 VIL - tRSH tAR tASR tRAH tRAL tCAH tASC Row Column tCWL tWCR tWCS VIH - WE VIL - tWCH tWP tRWL tDHR tDS DQ0-7 VIH - D8 VIL - tCRP tCAS tRAD Address VIH - VIL - tRP tRAS VIH - RAS V - IL tDH Valid Data-in Note: Q8 = "Open" "H" or "L" 9/13 Semiconductor MSC23409C/CL-xxDS9 Fast Page Mode Read Cycle tRASP RAS VIH - VIL - tCSH tRCD tCRP CAS VIH - CAS8 VIL - tPC tCAS tCP tCAS tAR tASC tRP tRSH tCAS tCP tCRP , , , tASR Address VIH - VIL - tRAH Row Column tRAD tRCH VIH - VIL - tCAH tRCS tRRH tRCS tRCH tCAC Valid Data-out tAA tCPA tCPA Valid Data-out tOFF tCLZ tCLZ tCAC tAA tAA tRAC DQ0-7 VOH - Q8 VOL - Column tRCH tCAC tRAL tCAH tASC Column tRCS WE tASC tCAH Valid Data-out tOFF tCLZ tOFF "H" or "L" Fast Page Mode Write Cycle (Early Write) tRP tRASP RAS VIH - VIL - tCRP CAS VIH - CAS8 VIL - tASR Address VIH - VIL - tCAS tRCD tRAH tCSH tAR tASC Row Column tWCR VIH - WE VIL - tWCS tDS DQ0-7 VIH - D8 VIL - tCAH tPC tCAS tCP tASC tCAH Column tRSH tCAS tCP tASC tCRP tRAL tCAH Column tRWL tCWL tWCH tWP tDH Valid Data-in tWCS tDS tCWL tWCH tWP tDH Valid Data-in tWCS tDS tCWL tWCH tWP tDH Valid Data-in tDHR Note: Q8 = "Open" "H" or "L" 10/13 , ,, Semiconductor MSC23409C/CL-xxDS9 RAS-Only Refresh Cycle tRC tRP RAS tRAS VIH - VIL - tCRP CAS VIH - CAS8 VIL - tASR Address VIH - VIL - tRPC tRAH Row tOFF DQ0-7 VOH - Q8 VOL - Open Note: WE = "H" or "L" "H" or "L" CAS before RAS Refresh Cycle tRC tRAS RAS VIH - VIL - tRPC tRP tRPC tCP tCSR tCHR tWRP tWRH CAS VIH - CAS8 VIL - tWRP WE VIH - VIL - tOFF DQ0-7 VOH - Q8 VOL - Open Note: Address = "H" or "L" "H" or "L" 11/13 Semiconductor MSC23409C/CL-xxDS9 ,,, ,,, Hidden Refresh Read Cycle tRC tRAS RAS VIH - VIL - tRCD tCRP CAS CAS8 VIH - VIL - VIH - VIL - tRSH tRAH tRAL tCAH tASC Row Column tAR tRCS WE VIH - VIL - tRRH tWRP tWRH tCAC tRAC DQ0-7 Q8 tCHR tRAD tASR Address tRAS tRP VOH - VOL - tAA tOFF Valid Data-out tCLZ "H" or "L" Hidden Refresh Write Cycle tRC tRAS V - RAS IH VIL - tRCD tCRP CAS VIH - CAS8 VIL - tRAD tASR Address VIH - VIL - tRAH Row tRAS tRP tRSH tCHR tAR tRAL tCAH tASC Column tWCR WE VIH - VIL - tRWL tWCH tWP tWCS tWRH tDH tDS DQ0-7 VIH - D8 VIL - tWRP Valid Data-in tDHR Note: Q8 = "Open" "H" or "L" 12/13 Semiconductor MSC23409C/CL-xxDS9 , , , , , CAS before RAS Refresh Counter Test Cycle tRAS tRP tRSH VIH - VIL - RAS tCSR tCHR tCPT tCAS CAS VIH - CAS8 VIL - tASC V - Address IH VIL - tCAH Column tCAC tRAL Read Cycle tAA DQ0-7 VOH - Q8 VOL - WE tWRH tCLZ tRCS tRCH tWRP tRWL tCWL tWCH tWRH tWCS VIH - VIL - tWP tDH tDS DQ0-7 VIH - D8 VIL - Q8 tRRH VIH - VIL - Write Cycle WE Valid Data-out Open tWRP tOFF Valid Data-in VOH - VOL - Open "H" or "L" WE * CAS before RAS Refresh Cycle tRC tRP RAS VIH - VIL - tRAS tRPC tCP tCSR tCHR CAS VIH - CAS8 VIL - tWTS tWTH WE VIH - VIL - tOFF DQ0-7 VOH - Q8 VOL - Open Note : Address = "H" or "L" "H" or "L" 13/13
