A new pattern can then be written rapidly to the de-
vice by following the programming procedure.
For applications where the content is programmed
only one time and erasure is not required, the
M27C160 is offered in PDIP42, PLCC44 and
SO44 packages.
DEVICE OPERATION
The operating modes of the M27C160 are listed in
the Operating Modes Table. A single power supply
is required in the read mode. All inputs are TTL
compatible except for V
Electronic Signature.
Read Mode
The M27C160 has two organisations, Word-wide
and Byte-wide. The organisation is selected by the
signal level on the BYTEV
is at V
and the Q15A–1 pin is used for Q15 Data Output.
When the BYTEV
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 V
lower 8 bits of the 16 bit data are selected and with
A–1 at V
selected.
