DESCRIPTION

The M27C64A is a 64Kbit EPROM offered in the

two ranges UV (ultra violet erase) and OTP (one

time programmable). It is ideally suited for microprocessor

systems requiring large programs and is

organized as 8,192 by 8 bits.

The FDIP28W (window ceramic frit-seal package)

has transparent lid which allows the user to expose

the chip to ultraviolet light to erase the bit pattern.

A new pattern can then be written to the device by

following the programming procedure.

For applications where the content is programmed

only on time and erasure is not required, the

M27C64A is offered in PLCC32 package.
