KM416C254D Scheda tecnica(HTML) 4 Page - Samsung semiconductor |
4 / 36 page KM416C254D, KM416V254D CMOS DRAM *Note : ICC1, ICC3, ICC4 and ICC6 are dependent on output loading and cycle rates. Specified values are obtained with the output open. ICC is specified as an average current. In ICC1, ICC3, ICC6 and ICC7, address can be changed maximum once while RAS=VIL. In ICC4, address can be changed maximum once within one Hyper page mode cycle time, tHPC. DC AND OPERATING CHARACTERISTICS (Continued) ICC1* : Operating Current (RAS and UCAS, LCAS, Address cycling @ tRC=min.) ICC2 : Standby Current (RAS=UCAS=LCAS=W=VIH) ICC3* : RAS-only Refresh Current (UCAS=LCAS=VIH, RAS, Address cycling @ tRC=min.) ICC4* : Extended Data Out Mode Current (RAS=VIL, UCAS or LCAS, Address cycling @ tHPC=min.) ICC5 : Standby Current (RAS=UCAS=LCAS=W=VCC-0.2V) ICC6* : CAS-Before-RAS Refresh Current (RAS and UCAS or LCAS cycling @ tRC=min.) ICC7 : Battery back-up current, Average power supply current, Battery back-up mode Input high voltage(VIH)=VCC-0.2V, Input low voltage(VIL)=0.2V, UCAS, LCAS=0.2V, DQ=Don ′t care, TRC=125us, TRAS=TRASmin~300ns ICCS : Self Refresh Current RAS=UCAS=LCAS=VIL, W=OE=A0 ~ A8=VCC-0.2V or 0.2V, DQ0 ~ DQ15=VCC-0.2V, 0.2V or Open Symbol Power Speed Max Units KM416V254D KM416C254D ICC1 Don ′t care -5 -6 -7 - 70 65 110 90 80 mA mA mA ICC2 Don ′t care Don ′t care 1 2 mA ICC3 Don ′t care -5 -6 -7 - 70 65 110 90 80 mA mA mA ICC4 Don ′t care -5 -6 -7 - 60 55 90 80 70 mA mA mA ICC5 Normal L Don ′t care 0.5 100 1 150 mA uA ICC6 Don ′t care -5 -6 -7 - 70 65 110 90 80 mA mA mA ICC7 L Don ′t care 200 300 uA ICCS L Don ′t care 100 200 uA |
