Operation within the t
RCD(max)
limit insures that t
RAC(max)
can be met. t
RCD(max)
is specified as a reference point.
Assumes that t
RCD
t
RCD(max)
.
t
AR
, t
WCR
, t
DHR
are referenced to t
RAD(max)
.
t
OFF(max)
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
and t
AWD
are non restrictive operating parameters. They are included in the datasheet as electrical
characteristics only. If t
WCS
t
WCS(min)
the cycle 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)
, then the cycle is a read-write cycle and the data
output will contain the data read from the selected address. If neither of the above conditions are 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 early write cycles and to the WE# leading edge in read-
write cycles.
Operation within the t
RAD(max)
limit ensures 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 the access time is controlled by t
AA
.
Refer to command definition tables for valid address and data values.
