The M27V160 has two organisations, Word-wide and Byte-wide. The organisation is
selected by the signal level on the BYTEV
organisation is selected and the Q15A–1 pin is used for Q15 Data Output. When the

the Byte-wide organisation, then with A–1 at V

The M27V160 has two control functions, both of which must be logically active in order to
obtain data at the outputs. In addition the Word-wide or Byte- wide organisation must be
selected.
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 independent of
device selection. Assuming that the addresses are stable, the address access time (t
is equal to the delay from E to output (t

The M27V160 has a standby mode which reduces the active current from 20mA to 20µA
with low voltage operation V
details.The M27V160 is placed in the standby mode by applying a CMOS high signal to the
