DEVICE OPERATION
The operating modes of the M27W201 are listed in
the Operating Modes table. A single power supply
is required in the read mode. All inputs are TTL
levels except for V
PP
and 12V on A9 for Electronic
Signature.
Read Mode
The M27W201 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.
Output Enable (G) is the output control and should
be used to gate data to the output pins, indepen-
dent of device selection. Assuming that the ad-
dresses are stable, the address access time
(t
AVQV
) is equal to the delay from E to output
(t
ELQV
). Data is available at the output after a delay
of t
GLQV
from the falling edge of G, assuming that
E has been low and the addresses have been sta-
ble for at least t
AVQV
-t
GLQV
.
Standby Mode
The M27W201 has a standby mode which reduc-
es the supply current from 15mA to 15μA with low
voltage operation V
CC
≤
3.6V, see Read Mode DC
Characteristics table for details.The M27W201 is
placed in the standby mode by applying a CMOS
high signal to the E input. When in the standby
mode, the outputs are in a high impedance state,
independent of the G input.
