Note the RAS may be cycled during the initial pause. And any eight initialization cycles are required after prolonged periods (greater than 64 ms) of RAS inactivity before proper device operation is achieved. 7: Measured with a load circuit equivalent to VOH=2.4V(IOH=-2mA) / VOL=0.4V(IOL=2mA) loads and 100pF. The reference levels for measuring of output signals are VOH=2.0V and VOL=0.8V. 8: Assumes that tRCD tRCD(max) and tASC tASC(max) and tCP tCP(max). 9: 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 will increase by amount that tRCD exceeds the value shown. 10: Assumes that tRAD tRAD(max) and tASC tASC(max). 11: Assumes that tCP tCP(max) and tASC tASC(max). 12: tOFF(max) and tOEZ(max) defines the time at which the output achieves the high impedance state (IOUT 10 A) and is not reference to VOH(min) or VOL(max). ≥ ≥ ≥ ≥ ≤ ≤ ≤ ≤ ≤ ± µ ≥ C Limits Min Max Unit Typ pF pF pF pF pF pF Input capacitance,address inputs CI (A) CI (OE) CI (RAS) CI (W) CI (CAS) CI / O Symbol Parameter Test conditions Input capacitance, OE input Input capacitance, write control input Input capacitance, RAS input Input capacitance, CAS input Input/Output capacitance, data ports 5 7 7 7 7 VI=Vss f=1MHZ Vi=25mVrms 7 CAPACITANCE (Ta=0 70 , Vcc=3.3 0.3V, Vss=0V, unless otherwise noted) ~ ± 0 0 0 0 |
