Notes:
1) All voltages are referenced to
V
SS
.
2)
I
CC1
,
I
CC3
,
I
CC4
and
I
CC6
depend on cycle rate.
3)
I
CC1
and
I
CC4
depend on output loading.
Specified values are measured with the output open.
4) An initial pause of 200
μ
s is required after power-up followed by 8 RAS cycles out of which at least one cycle
has to be a refresh cycle before proper device operation is achieved. In case of using internal refresh counter,
a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required.
5)
V
IH (max)
and
V
IL (max)
are reference levels for measuring timing of input signals.
Transition times are also measured between
V
IH
and
V
IL
.
6) Measured with a load equivalent of 2 TTL loads and 100 pF.
7)
t
OFF (max)
defines the time at which the output achieves the open-circuit condition and is not referenced to output
voltage levels.
8) Either
t
RCH
or
t
RRH
must be satisfied for a read cycle.
9) These parameters are referenced to the CAS leading edge.
10)
t
WCS
is not a restrictive operating parameter. This is included in the data sheet as electrical characteristic only.
If
t
WCS
>
t
WCS (min)
, the cycle is an early write cycle and data out pin will remain open (high impedance).
11) Operation within the
t
RCD (max)
limit insures that
t
RAC (max)
can be met.
t
RCD (max)
is specified as a reference point
only. If
t
RCD
is greater than the specified
t
RCD (max)
limit, then access time is controlled by
t
CAS
.
12) Operation within the
t
RAD (max)
limit insures that
t
RAC (max)
can be met.
t
RAD (max)
is specified as a reference point
only. If
t
RAD
is greater than the specified
t
RAD (max)
limit, then access time is controlled by
t
AA
.
13) For CAS-before-RAS cycles only.
