M27W801-100B6TR
Description
8 Mbit 1Mb x8 Low Voltage UV EPROM and OTP EPROM
Manufacturer

Datasheet
DESCRIPTION
The M27W801 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 and is organized as 1,048,576 by
8 bits.
The M27W801 operates in the read mode with a
supply voltage as low as 2.7V at –40 to 85 C tem-
perature range. The decrease in operating power
allows either a reduction of the size of the battery
or an increase in the time between battery re-
charges.
The FDIP32W (window ceramic frit-seal package)
has a transparent lids which allow 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
M27W801 is offered in PDIP32, PLCC32 and
TSOP32 (8 x 20 mm) packages.
