Manufacturer Part Number

Description
16 Mbit 2Mb x8 or 1Mb x16 Low Voltage UV EPROM and OTP EPROM

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.

... Q11 22 23 AI01900 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 V and 12V on A9 for the PP Electronic Signature. Read Mode The M27V160 has two organisations, Word-wide and Byte-wide ...

... IL Device Code 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 ...
