Notes: 1. H: High (inactive) L: Low (active) D: H or L 2. tWCS 0 ns Early write cycle tWCS < 0 ns Delayed write cycle 3. Mode is determined by the OR function of the UCAS and LCAS. (Mode is set by the earliest of UCAS and LCAS active edge and reset by the latest of UCAS and LCAS inactive edge.) However write OPERATION and output High-Z control are done independently by each UCAS, LCAS. ex. if RAS = H to L, UCAS = H, LCAS = L, then CAS-before-RAS refresh cycle is selected.

HM51W16160 Series, HM51W18160 Series
Notes: 1. AC measurements assume tT = 5 ns. 2. An initial pause of 200 s 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). If the internal refresh counter is used, a minimum of eight CAS-before-RAS refresh cycles are required. 3. Operation with the tRCD (max) limit insures 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 access time is controlled exclusively by tCAC . 4. Operation with the tRAD (max) limit insures 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 access time is controlled exclusively by tAA . 5. Either tOED or tCDD must be satisfied. 6. Either tDZO 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 VIH (min) and VIL (max). 8. Assumes that tRCD tRCD (max) and tRAD tRAD (max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, tRAC exceeds the value shown. 9. Measured with a load circuit equivalent to 1 TTL loads and 100 pF. (V OH = 2.0 V, VOL = 0.8 V) 10. Assumes that tRCD tRCD (max) and tRCD + tCAC (max) tRAD + tAA (max). 11. Assumes that tRAD tRAD (max) and tRCD + tCAC (max) tRAD + tAA (max). 12. Either tRCH or tRRH must be satisfied for a read cycles. 13. tOFF (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. tWCS , tRWD, tCWD, tAWD and tCPW are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only; if tWCS 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 tCPW (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. tRASP defines RAS pulse width in fast page mode cycles. 17. Access time is determined by the longest among tAA , tCAC and tCPA. 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 VCC and VSS pins shall be supplied with the same voltages. 21. tASC, tCAH, tRCS, tWCS, tWCH, tCSR and tRPC are determined by the earlier falling edge of UCAS or LCAS. 22. tCRP , tCHR, tRCH, tCPA and tCPW are determined by the later rising edge of UCAS or LCAS. 23. tCWL, tDH and tDS should be satisfied by both UCAS and LCAS. 24. tCP is determined by the time that both UCAS and LCAS are high. 25. 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 VCC/VSS line noise, which causes to degrade VIH min/VIL max level. 26. Please do not use tRASS timing, 10 s tRASS 100 s. During this period, the device is in transition state from normal operation mode to self refresh mode. If tRASS 100 s, then RAS precharge time should use tRPS instead of tRP.

27. If you use distributed CBR refresh mode with 15.6 s interval in normal read/write cycle, CBR refresh should be executed within 15.6 s immediately after exiting from and before entering into self refresh mode. 28. If you use RAS only refresh or CBR burst refresh mode in normal read/write cycle, 4096 or 1024 cycles (4096 cycles: HM51W16160 Series, 1024 cycles: HM51W18160 Series) of distributed CBR refresh with 15.6 s interval should be executed within 64 or 16 ms (64 ms: HM51W16160, 16 ms: HM51W18160) immediately after exiting from and before entering into the self refresh mode. 29. 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. 30. 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.

Notes concerning 2CAS control
Please do not separate the UCAS/LCAS operation timing intentionally. 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. However skew between
RAS Delayed write UCAS Early write LCAS
WE
3. Closely separated upper/lower byte control is not allowed. However when the condition (t CP tU L) is satisfied, fast page mode can be performed.
RAS
UCAS
LCAS t UL
4. Byte control operation by remaining UCAS or LCAS high is guaranteed.
