DESCRIPTION
The M27C64A is a high speed 65,536 bit UV eras-
able and electrically programmable memory
EPROM ideally suited for microprocessor systems
requiring large programs. It is organized as 8,192
by 8 bits.
The 28 pin Window Ceramic Frit-Seal Dual-in-Line
package has transparent lid which allows the user
to expose the chip to ultraviolet light to erase the
bit pattern. Anew 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 Plastic Leaded Chip Carrier
package.
