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=CAS-before-RAS cycling or 0.2V
W, OE=VIH, Address=Don′t care, DQ=Open, TRC=31.25us
ICCS : Self Refresh Current
RAS=UCAS=LCAS=0.2V, W=OE=A0 ~ A12(A11)=VCC-0.2V or 0.2V, DQ0 ~ DQ15=VCC-0.2V, 0.2V or Open
*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 and ICC6, address can be changed maximum once while RAS=VIL. In ICC4,
address can be changed maximum once within one EDO mode cycle time, tHPC.
