MR27V3202D
2,097,152-Word x 16-Bit or 4,194,304-Word x 8-Bit One Time PROM
1A
DESCRIPTION
The MR27V3202D is a 32Mbit electrically Programmable Read-Only Memory whose configuration
can be electrically switched between 2,097,152 word x 16bit and 4,194,304 word x 8bit. The MR27
V3202D operates on a single +3V-3.3V power supply and is TTL compatible. Since the MR27V3202
D operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V3202D 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 or 48-
pin TSOP packages.
