*1 : Maximum value is applicable if CE1r is kept at Low without change of address input of A20 to A3.
If needed by system operation, please contact local FUJITSU representative for the relaxation of 1 µs limitation.
*2 : Address should not be changed within minimum tRC.
*3 : The output load 30 pF.
*4 : The output load 5 pF without any other load.
*5 : Applicable to A20 to A3 when CE1r is kept at Low.
*6 : Applicable only to A2, A1 and A0 when CE1r is kept at Low for the page address access.
*7 : In case Page Read Cycle is continued with keeping CE1r stays Low, CE1r must be brought to High within 4 µs.
In other words, Page Read Cycle must be closed within 4 µs.
*8 : Applicable when at least two of address inputs among applicable are switched from previous state.
*9 : tRC(Min) and tPRC(Min) must be satisfied.
