DEVICE OPERATION
The modes of operations of the M27C1024 are
listed in the Operating Modes table. A single power
supply is required in the read mode. All inputs are
TTL levels except for Vpp and 12V on A9 for
Electronic Signature.
Read Mode
The M27C1024 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, inde-
pendent of device selection. Assuming that the
addresses are stable, the address access time
(tAVQV) is equalto the delay from E to output (tELQV).
Data is available at the output after a delay of tOE
from the falling edge of G, assuming that E has
been low and the addresses have been stable for
at least tAVQV-tGLQV.
Standby Mode
The M27C1024 has a standby mode which re-
duces the active current from 35mA to 100
ยตA.
The M27C1024 is placed in the standby mode by
applying a TTL high signal to the E input. When in
the standby mode, the outputs are in a high imped-
ance state, independent of the G input.
