prime concern. Enabling
CE
will cause transient current
spikes. The magnitude of these spikes is dependent on
the output capacitive loading of the l/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 suppressed by the proper
selection and placement of decoupling capacitors. As a
minimum, it is recommended that a 0.1
μ
F high fre-
quency ceramic capacitor be used between V
CC
and
V
SS
at each device. Depending 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.
SYSTEM CONSIDERATIONS
Because the X2804C 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 elimi-
nate the possibility of contention where multiple 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 X2804C has two power modes, standby
and active, proper decoupling of the memory array is of
