DESCRIPTION
The M27512 is a 524,288 bit UV erasable and
electrically programmable memory EPROM. It is
organized as 65,536 words by 8 bits.
The M27512 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 pat-
tern can then be written to the device by following
the programming procedure.
