DESCRIPTION
The M27128A is a 131,072 bit UV erasable and
electrically programmable memory EPROM. It is
organized as 16,384 words by 8 bits.
The M27128A is housed in a 28 Pin Window Ce-
ramic Frit-Seal Dual-in-Line package. The trans-
parent 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 follow-
ing the programming procedure.
