DESCRIPTION
The M27W102 is a low voltage 1 Mbit EPROM
offeredin 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 and is organized as 65,536 words
by 16 bits.
The M27V102 operates in the read mode with a
supply voltage as low as 3V. The decrease in
operating power allows either a reduction of the
size of the battery or an increase in the time be-
tween battery recharges.
The FDIP40W (window ceramic frit-seal package)
has a transparent lid which allows the user to
expose the chip to ultraviolet light to erase the bit
pattern. A new pattern can then be written to the
device by following the programming procedure.

DESCRIPTION (cont’d)
For application where the content is programmed
only one time and erasure is not required, the
M27V102 is offered in PDIP40, PLCC32 and
TSOP40 (10 x 14 mm) packages.
DEVICE OPERATION
The operating modes of the M27V102 are listed in
the Operating Modes table. A single power supply
is required in the read mode. All inputs are TTL
levels except for Vpp and 12V on A9 for Electronic
Signature.
Read Mode
The M27V102 has two control functions, both of
which must be logically active in order to obtaindata
at the outputs. 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 (tAVQV) is equal to
the delay from E to output (tELQV). Data is available
at the output after a delay of tOE from the falling
edge of G, assuming that E has been low and the
addresses have been stable for at least tAVQV-
tGLQV.
