DESCRIPTION

The M27C512 is a 512 Kbit 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 65,536 by 8 bits.

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

M27C512 is offered in PDIP28, PLCC32 and

TSOP28 (8 x 13.4 mm) packages.
