DESCRIPTION
The M27W800 is a low voltage 8 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 1 Mbit
words of 8 bit or 512 Kbit words of 16 bit. The pin-
out is compatible with a 8 Mbit Mask ROM.
The M27W800 operates in the read mode with a
supply voltage as low as 2.7V. 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 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
M27W800 is offered in PDIP42 and PLCC44 pack-
age.

DEVICE OPERATION
The operating modes of the M27W800 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 M27W800 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.
The M27W800 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
output control and should be used to gate data to
the output pins independent of device selection.
Assuming that the addresses are stable, the ad-
dress access time (tAVQV) is equal to the delay
from E to output (tELQV). Data is available at the
output after a delay of tGLQV from the falling edge
of G, assuming that E has been low and the ad-
dresses have been stable for at least tAVQV-tGLQV.

Note: 1. Except for the rating "Operating Temperature Range", stresses above those listed in the Table "Absolute Maximum Ratings" may
cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions
above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating condi-
tions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant qual-
ity documents.
2. Minimum DC voltage on Input or Output is –0.5V with possible undershoot to –2.0V for a period less than 20ns. Maximum DC
voltage on Output is VCC +0.5V with possible overshoot to VCC +2V for a period less than 20ns.
3. Depends on range.
