AC measurements assume t T = 2 ns. 2. An initial pause of 200 µs is required after power up followed by a minimum of eight initialization cycles (any combination of cycles containing RAS-only refresh or CAS-before-RAS refresh). 3. Operation with the tRCD (max) limit insures that tRAC (max) can be met, tRCD (max) is specified as a reference point only; if t RCD ≥ tRAD (max) + tAA (max) – tCAC (max), then access time is controlled exclusively by t CAC . 4. Operation with the tRAD (max) limit insures that tRAC (max) can be met, tRAD (max) is specified as a reference point only; if t RAD is greater than the specified tRAD (max) limit, then access time is controlled exclusively by tAA . 5. Either t OED or tCDD must be satisfied. 6. Either t DZO or tDZC must be satisfied. 7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition times are measured between V IH (min) and VIL (max). 8. Assumes that t RCD ≤ tRCD (max) and tRAD ≤ tRAD (max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, t RAC exceeds the value shown. 9. Measured with a load circuit equivalent to 1 TTL loads and 100 pF. 10. Assumes that t RCD ≥ tRCD (max) and tRCD + tCAC (max) ≥ tRAD + tAA (max). 11. Assumes that t RAD ≥ tRAD (max) and tRCD + tCAC (max) ≤ tRAD + tAA (max). 12. Either t RCH or tRRH must be satisfied for a read cycles. 13. t OFF (max) and tOEZ (max) define the time at which the outputs achieve the open circuit condition and are not referred to output voltage levels. 14. t WCS , t RWD, t CWD, t AWD and t CPW are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only; if t WCS ≥ tWCS (min), the cycle is an early write cycle and the data out pin will remain open circuit (high impedance) throughout the entire cycle; if tRWD ≥ tRWD (min), tCWD ≥ tCWD (min), and tAWD ≥ tAWD (min), or tCWD ≥ tCWD (min), tAWD ≥ tAWD (min) and tCPW ≥ t CPW (min), the cycle is a read-modify-write and the data output will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, the condition of the data out (at access time) is indeterminate. 15. These parameters are referred to UCAS and LCAS leading edge in early write cycles and to WE leading edge in delayed write or read-modify-write cycles. 16. t RASP defines RAS pulse width in EDO page mode cycles. 17. Access time is determined by the longest among t AA , t CAC and t CPA. 18. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device 19. When both UCAS and LCAS go low at the same time, all 16-bit data are written into the device. UCAS and LCAS cannot be staggered within the same write/read cycles. 20 All the V CC and VSS pins shall be supplied with the same voltages. 15 This Material Copyrighted By Its Respective Manufacturer HM51W16165 Series, HM51W18165 Series 21. t ASC, tCAH , t RCS , t WCS , t WCH, t CSR and t RPC are determined by the earlier falling edge of UCAS or LCAS. 22. t CRP , t CHR, t RCH, t CPA and tCPW are determined by the later rising edge of UCAS or LCAS. 23. t CWL, t DH, t DS and t CHS should be satisfied by both UCAS and LCAS. 24. t CP is determined by the time that both UCAS and LCAS are high. 25. t HPC (min) can be achieved during a series of EDO page mode write cycles or EDO page mode read cycles. If both write and read operation are mixed in a EDO page mode RAS cycle (EDO page mode mix cycle (1), (2)), minimum value of CAS cycle (tCAS + tCP + 2 tT) becomes greater than the specified t HPC (min) value. The value of CAS cycle time of mixed EDO page mode is shown in EDO page mode mix cycle (1) and (2). 26. When output buffers are enabled once, sustain the low impedance state until valid data is obtained. When output buffer is turned on and off within a very short time, generally it causes large V CC/V SS line noise, which causes to degrade V IH min/VIL max level. 27. Data output turns off and becomes high impedance from later rising edge of RAS and CAS. Hold time and turn off time are specified by the timing specifications of later rising edge of RAS and CAS between t OHR and t OH, and between tOFR and t OFF. 28. Please do not use tRASS timing, 10 µs ≤ tRASS ≤ 100 µs. During this period, the device is in transition state from normal operation mode to self refresh mode. If t RASS ≥ 100 µs, then RAS precharge time should use tRPS instead of tRP. 29. If you use distributed CBR refresh mode with 15.6 µs interval in normal read/write cycle, CBR refresh should be executed within 15.6 µs immediately after exiting from and before entering into self refresh mode. 30. If you use RAS only refresh or CBR burst refresh mode in normal read/write cycle, 4096 or 1024 cycles (4096 cycles: HM51W16165 Series, 1024 cycles: HM51W18165 Series) of distributed CBR refresh with 15.6 µs interval should be executed within 64 or 16 ms (64 ms: HM51W16165, 16 ms: HM51W18165) immediately after exiting from and before entering into the self refresh mode. 31. Repetitive self refresh mode without refreshing all memory is not allowed. Once you exit from self fresh mode, all memory cells need to be refreshed before re-entering the self refresh mode again. 32. XXX: H or L (H: VIH (min) ≤ VIN ≤ VIH (max), L: VIL (min) ≤ VIN ≤ VIL (max)) ///////: Invalid Dout When the address, clock and input pins are not described on timing waveforms, their pins must be applied VIH or VIL. 16 This Material Copyrighted By Its Respective Manufacturer HM51W16165 Series, HM51W18165 Series Notes concerning 2CAS control Please do not separate the UCAS/LCAS operation timing intentionally. However skew between UCAS/LCAS are allowed under the following conditions. 1. Each of the UCAS/LCAS should satisfy the timing specifications individually. 2. Different operation mode for upper/lower byte is not allowed; such as following. RAS Delayed write UCAS Early write LCAS WE 3. Closely separated upper/lower byte control is not allowed. However when the condition (tCP ≤ tUL) is satisfied, EDO page mode can be performed. RAS UCAS LCAS t UL 4. Byte control operation by remaining UCAS or LCAS high is guaranteed. 17 This Material Copyrighted By Its Respective Manufacturer HM51W16165 Series, HM51W18165 Series Timing Waveforms*32 Read Cycle t
