A new pattern can then be written to the device by
following the programming procedure.
For applications where the content is programmed
only one time and erasure is not required, the
M27V201 is offered in PDIP32, PLCC32 and
TSOP32 (8 x 20 mm) packages.
DEVICE OPERATION
The operating modes of the M27V201 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
Signature.
Read Mode
The M27V201 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
