DESCRIPTION

The M27W512 is a low voltage 512 Kbit EPROM

offered in the two range UV (ultra violet erase) and

OTP (one time programmable). It is ideally suited

for microprocessor systems and is organized as

65,536 by 8 bits.

The M27W512 operates in the read mode with a

supply voltage as low as 2.7V at 鈥?0 to 85擄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 FDIP28W (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

M27W512 is offered in PDIP28, PLCC32 and

TSOP28 (8 x 13.4 mm) packages.
