M27V800
The M27V800 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 chipto 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 wherethe content is programmed
only one time and erasure is not required, the
M27V800 is offered in PDIP42, SO44 and
PLCC44 package.
DEVICE OPERATION
The operating modes of the M27V800 are listed in
the Operating Modes Table.A singlepower supply
is required in the read mode. All inputs are TTL
compatible except for V
PP
and 12V on A9 for the
Electronic Signature.
Read Mode
The M27V800 has two organisations, Word-wide
and Byte-wide.The organisation is selected bythe
signal level on the BYTEV
PP
pin. When BYTEV
PP
is at V
IH
the Word-wide organisation is selected
and the Q15A–1 pin is used for Q15 Data Output.
When the BYTEV
PP
pinis at V
IL
the Byte-wide or-
ganisation is selected and theQ15A–1 pin isused
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
IL
the
lower 8 bits of the 16bit data are selected and with
A–1 at V
IH
the upper 8 bits of the 16 bit data are
selected.
The M27V800 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 thepower 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 (t
AVQV
) is equal to the delay
from E to output (t
ELQV
). Data is available at the
output after a delay of t
GLQV
from the falling edge
of G, assuming that E has been low and the ad-
dresses have been stable for at least t
AVQV
