NOTES
An initial pause of 200us is required after power-up followed by any 8 ROR or CBR cycles before proper device operation is
achieved.
Input voltage levels are Vih/Vil. V
IH
(min) and V
IL
(max) are reference levels for measuring timing of input signals.
Transition times are measured between V
IH
(min) and V
IL
(max) and are assumed to be 5ns for all inputs.
Measured with a load equivalent to 2 TTL(5V)/1TTL(3.3V) loads and 100pF.
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 exclusively by
t
CAC
.
This parameter defines the time at which the output achieves the open circuit condition and is not referenced to V
oh
or V
ol
.
t
WCS
,
t
RWD
,
t
CWD
,
t
AWD
and
t
CPWD
are non restrictive operating parameters. They are included in the data sheet as electrical
characteristics only. If
t
WCS
t
WCS
(min), the cycles is an early write cycle and the data output will remain high impedance for
the duration of the cycle. If
t
CWD
t
CWD
(min),
t
RWD
t
RWD
(min),
t
AWD
t
AWD
(min) and
t
CPWD
t
CPWD
(min), then the cycle is a
read-modify-write cycle and the data output will contain the data read from the selected address. If neither of the above condi-
tions is satisfied, the condition of the data out is indeterminate.
Either
t
RCH
or
t
RRH
must be satisfied for a read cycle.
These parameters are referenced to the CAS leading edge in ealy write cycles and to the W falling edge in OE controlled write
cycle and read-modify-write cycles.
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
.
