DESCRIPTION
The M27W202 is a low voltage 2 Mbit EPROM of-
fered in the two range UV (ultra violet erase) and
OTP (one time programmable). It is ideally suited
for microprocessor systems requiring large data or
program storage and is organised as 131,072 by
16 bits.
The M27W202 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 FDIP40W (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 to the
device by following the programming procedure.
For application where the content is programmed
only one time and erasure is not required, the
M27W201 is offered in PDIP40, PLCC44 and
TSOP40 (10 x 14 mm) packages.
