(2) stress greater than those listed under ?absolute maximum ratings? may cause permanent damage to the device. this is a stress rating only and functional operation at these or any other conditions greater than those indicated in the operational sections of this specification is not implied. exposure to absolute maximum rating conditions for extended periods may affect reliability. sym parameter density (mbytes) notes typ (4) max units test conditions i ccr v cc read current all 75 ma v cc = v cc max tcycle = 150ns,cmos levels i ccw v cc program current all 150 ma i cce v cc erase current all 150 ma i ccs (cmos) v cc standby current 2mb (4mb) 2,3 80 230 a v cc = v cc max control signals = v cc reset = v ss , cmos levels notes: 1. all currents are rms values unless otherwise specified. iccr, iccw and icce are based on word wide operations. 2. control signals: ce 1 #, ce 2 #, oe#, we#, reg#. 3. iccd and iccs are specified for lowest density card for each component type (2mb for 8mb components and 4mb for 16mb components) this represents a single pair of devices. for higher densities multiply the number of device pairs by the specified current in the table. for example a 40mb card will use 10 device pairs of 16mb components. the maximum iccd will be 10 x 40a = 400a. the maximum iccs will be 10 x 230a = 2.3ma. 4. typical: v cc = 5v, t = +25c. cmos test conditions: v cc = 5v 5%, vil = v ss 0.2v, vih = v cc 0.2v dc characteristics (1) symbol parameter notes min max units test conditions i li input leakage current 1 20 a v cc = v cc max vin =v cc or v ss i lo output leakage current 1 20 a v cc = v cc max vout =v cc or v ss v il input low voltage 1 0 0.8 v v ih input high voltage 1 0.7v cc v cc +0.5 v v ol output low voltage 1 0.4 v iol = 3.2ma v oh output high voltage 1 v cc -0.4 v cc vioh = -2.0ma v lko v cc erase/program lock voltage 12.0 v ** advanced information. notes: 1. values are the same for byte and word wide modes for all card densities. 2. exceptions: leakage currents on ce1#, ce2#, oe#, reg# and we# will be < 500 a when vin = gnd due to internal pull-up resistors. leakage currents on rst will be <150a when vin=v cc due to internal pull-down resistor.
