MR27V3255D
1,048,576-Double Word x 32-Bit or 2,097,152-Word x 16-Bit
8-Double Word x 32-Bit or 16-Word x 16-Bit Page Mode One Time PROM
DESCRIPTION
1A
The MR27V3255D is a 32Mbit electrically Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between 1,048,576 double word x 32bit and 2,097,152
word x 16bit. The MR27V3255D operates on a single +3.3V power supply and is TTL compatible.
The MR27V3255D provides Page mode which can greatly reduce the read access time. Since the
MR27V3255D operates asynchronously , external clocks are not required , making this device easy-
to-use. The MR27V3255D 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 70-pin
SSOP or 70-pin TSOP packages.
