DESCRIPTION
The M27C801 is an 8 Mbit EPROM offered in the
two ranges UV (ultra violet erase) and OTP (one
time programmable). It is ideally suited for applica-
tions where fast turn-around and pattern experi-
mentation are important requirements and is
organized as 1,048,576 by 8 bits.
The FDIP32W (window ceramic frit-seal package)
has 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 to the
device by following the programming procedure.
For applications where the content is programmed
only one time and erasure is not required, the
M27C801 is offered in PDIP32, PLCC32 and
TSOP32 (8 x 20 mm) packages.

Two Line Output Control
Because EPROMs are usually used in larger
memory arrays, the product features a 2 line con-
trol function which accommodates the use of mul-
tiple memory connection. The two line control
function allows:
a. the lowest possible memory power dissipation,
b. complete assurance that output bus contention
will not occur.
For the most efficient use of these two control
lines, E should be decoded and used as the prima-
ry device selecting function, while G should be
made a common connection to all devices in the
array and connected to the READ line from the
system control bus. This ensures that all deselect-
ed memory devices are in their low power standby
mode and that the output pins are only active
when data is required from a particular memory
device.
