DEVICE OPERATION
The modes of operations of the M27C512 are list-
ed in the Operating Modes table. A single power
supply is required in the read mode. All inputs are
TTL levels except for GVPP and 12V on A9 for
Electronic Signature.
Read Mode
The M27C512 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.
Standby Mode
The M27C512 has a standby mode which reduces
the active current from 30mA to 100
AThe
M27C512 is placed in the standby mode by apply-
ing a CMOS high signal to the E input. When in the
standby mode, the outputs are in a high imped-
ance state, independent of the GVPP input.
