MR27V6402D
DESCRIPTION
1A
Preliminary
4,194,304-Word x 16-Bit or 8,388,608-Word x 8-Bit One Time PROM
The MR27V6402D is a 64Mbit electrically Programmable Read-Only Memory whose configuration
can be electrically switched between 4,194,304 word x 16bit and 8,388,608 word x 8bit. The MR27
V6402D operates on a single +3V-3.3V power supply and is TTL compatible. Since the MR27V6402
D operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V6402D is suitable as large-capacity fixed memory for microcomputers and data terminals. It is
manufactured using a CMOS double silicon gate technology and is offered in 44-pin SOP package.
