DEVICEOPERATION
The operating modes of the M27C4002 are listed
in the OperatingModes table. Asingle power sup-
plyis requiredin theread mode. AllinputsareTTL
levels except for V
pp
and 12V on A9 for Electronic
Signature.
Read Mode
The M27C4002 has two control functions,both of
which must be logically active in order to obtain
data at the outputs. Chip Enable (E) is the power
control and should be used for device selection.
OutputEnable(G) is the outputcontroland should
be used to gate data to the output pins, inde-
pendent of device selection. Assuming that the
addresses are stable, the address access time
(t
AVQV
)isequalto thedelayfromEtooutput(t
ELQV
).
Datais availableat theoutputaftera delayof t
GLQV
from the falling edge of G, assuming that E has
been low and the addresseshave been stable for
at least t
AVQV
-t
GLQV
.
Standby Mode
The M27C4002 has a standby mode which re-
ducesthesupplycurrentfrom50mAto100
μ
A.The
M27C4002 is placed in the standby mode by ap-
plying a CMOShigh signalto theE input. Whenin
thestandbymode,theoutputsare inahighimped-
ance state,independentof the G input.
