DESCRIPTION
The M27256 is a 262,144 bit UV erasable and
electrically programmable memory EPROM. It is
organized as 32.768 words by 8 bits.
The M27256 is housed in a 28 pin Window Ceram-
ic Frit-Seal Dual-in-Line package. The transparent
lid 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 pro-
gramming procedure.
