SYSTEM CONSIDERATIONS
Because the X28LC512/513 is frequently used in large
memory arrays it is provided with a two line control
architecture for both read and write operations. Proper
usage can provide the lowest possible power dissipation
and eliminate the possibility of contention where mul-
tiple I/O pins share the same bus.
To gain the most benefit it is recommended that
CE
be
decoded from the address bus and be used as the
primary device selection input. Both
OE
and
WE
would
then be common among all devices in the array. For a
read operation this assures that all deselected devices
are in their standby mode and that only the selected
device(s) is outputting data on the bus.
Because the X28LC512/513 has two power modes,
standby and active, proper decoupling of the memory
array is of prime concern. Enabling
CE
will cause
transient current spikes. The magnitude of these spikes
is dependent on the output capacitive loading of the I/
Os. Therefore, the larger the array sharing a common
bus, the larger the transient spikes. The voltage peaks
associated with the current transients can be sup-
pressed by the proper selection and placement of
decoupling capacitors. As a minimum, it is recom-
mended that a 0.1
μ
F high frequency ceramic capacitor
be used between V
CC
and V
SS
at each device. Depend-
ing on the size of the array, the value of the capacitor
may have to be larger.
In addition, it is recommended that a 4.7
μ
F electrolytic
bulk capacitor be placed between V
CC
and V
SS
for each
eight devices employed in the array. This bulk capacitor
is employed to overcome the voltage droop caused by
the inductive effects of the PC board traces.
