DESCRIPTION
The M27V160 is a low voltage 16 Mbit EPROM of-
fered in the two ranges UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited
for microprocessor systems requiring large data or
program storage. It is organised as either 2 Mbit
words of 8 bit or 1 Mbit words of 16 bit. The pin-out
is compatible with a 16 Mbit Mask ROM.
The M27V160 operates in the read mode with a
supply voltage as low as 3V. The decrease in op-
erating power allows either a reduction of the size
of the battery or an increase in the time between
battery recharges.
The FDIP42W (window ceramic frit-seal package)
has a transparent lid which allows the user to ex-
pose the chip to ultraviolet light to erase the bit pat-
tern. A new pattern can then be written rapidly to
the device by following the programming proce-
dure.
For applications where the content is programmed
only one time and erasure is not required, the
M27V160 is offered in PDIP42 and SO44 packag-
es.

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.
