Notes
1. For proper power-up see the operation section of this data sheet.
2. AC timing tests
for LV-TTL versions
have
V
IL
= 0.4 V and
V
IH
= 2.4 V with the timing referenced to
the 1.4 V crossover point. The transition time is measured between
V
IH
and
V
IL
. All AC
measurements assume
t
T
= 1 ns with the AC output load circuit shown in figure below. Specified
t
AC
and
t
OH
parameters are measured with a 50 pF only, without any resistive termination and
with a input signal of 1V / ns edge rate between 0.8 V and 2.0 V.
3. If clock rising time is longer than 1 ns, a time (
t
T
/2
0.5) ns has to be added to this parameter.
4. If
t
T
is longer than 1 ns, a time (
t
T
1) ns has to be added to this parameter.
5. These parameter account for the number of clock cycle and depend on the operating frequency
of the clock, as follows:
the number of clock cycle = specified value of timing period (counted in fractions as a whole
number)
6. Access time from clock
t
AC
is 4.6 ns for PC133 components with no termination and 0 pF load,
Data out hold time
t
OH
is 1.8 ns for PC133 components with no termination and 0 pF load.
7. Self Refresh Exit is a synchronous operation and begins on the second positive clock edge after
CKE returns high. Self Refresh Exit is not complete until a time period equal to
t
RC
is satisfied
once the Self Refresh Exit command is registered.
