DEVICE OPERATION
The modes of operation of the M27C64A are listed
in the Operating Modes table. A single power sup-
ply is required in the read mode. All inputs are TTL
levels except for VPP and 12V on A9 for Electronic
Signature.
Read Mode
The M27C64A 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
(tAVQV) is equal to the delay from E to output
(tELQV). Data is available at the output after a delay
of tGLQV from the falling edge of G, assuming that
E has been low and the addresses have been sta-
ble for at least tAVQV-tGLQV.
