DEVICE OPERATION
The operating modes of the M27V160 are listed in
the Operating Modes Table. A single power supply
is required in the read mode. All inputs are TTL
compatible except for VPP and 12V on A9 for the
Electronic Signature.
Read Mode
The M27V160 has two organisations, Word-wide
and Byte-wide. The organisation is selected by the
signal level on the BYTEVPP pin. When BYTEVPP
is at VIH the Word-wide organisation is selected
and the Q15A–1 pin is used for Q15 Data Output.
When the BYTEVPP pin is at VIL the Byte-wide or-
ganisation is selected and the Q15A–1 pin is used
for the Address Input A–1. When the memory is
logically regarded as 16 bit wide, but read in the
Byte-wide organisation, then with A–1 at VIL the
lower 8 bits of the 16 bit data are selected and with
A–1 at VIH the upper 8 bits of the 16 bit data are
selected.
