AC Characteristics
(T
A
= 0 to +70
°
C, V
DD
= 3.3V to 3.6V)
1. An initial pause of 200
μ
s is required after power-up, then a Precharge All Banks command must be given
followed by a minimum of eight Auto (CBR) Refresh cycles before or after the Mode Register Set opera-
tion can begin.
2. AC timing tests have V
IL
= 0.8V and V
IH
= 2.0V with the timing referenced to the 1.40V crossover point.
3. The Transition time is measured between V
IH
and V
IL
(or between V
IL
and V
IH
).
4. AC measurements assume t
T
=1ns.
5. In addition to meeting the transition rate specification, the clock and CKE0 must transit between V
IH
and
V
IL
(or between V
IL
and V
IH
) in a monotonic manner.
