Revision A6
Standby Mode
The standby mode significantly reduces V
CC
current. This mode is entered when CE = V
IH
. In
standby mode, all outputs are in a high impedance state, independent of OE and PGM.
Two-line Output Control
Since EPROMs are often used in large memory arrays, the W27E010 provides two control inputs for
multiple memory connections. Two-line control provides for lowest possible memory power
dissipation and ensures that data bus contention will not occur.
System Considerations
EPROM power switching characteristics require careful device decoupling. System designers are
concerned with three supply current issues: standby current levels (I
SB
), active current levels (I
CC
),
and transient current peaks produced by the falling and rising edges of CE. Transient current
magnitudes depend on the device output's capacitive and inductive loading. Two-line control and
proper decoupling capacitor selection will suppress transient voltage peaks. Each device should have
a 0.1
μ
F ceramic capacitor connected between its V
CC
and GND. This high frequency, low inherent-
inductance capacitor should be placed as close as possible to the device. Additionally, for every eight
devices, a 4.7
μ
F electrolytic capacitor should be placed at the array's power supply connection
between V
CC
and GND. The bulk capacitor will overcome voltage slumps caused by PC board trace
inductances.
