DESCRIPTION
The MR27V3252D is a 32Mbit electrically Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between 2,097,152 word x 16bit and 4,194,304 word x 8
bit. The MR27V3252D operates on a single +3.3V power supply and is TTL compatible. The MR27
V3252D provides Page mode which can greatly reduce the read access time. Since the MR27V3252
D operates asynchronously , external clocks are not required , making this device easy-to-use. The
MR27V3252D 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.
