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

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.

FEATURES

• 1,048,576 double word x 32bit / 2,097,152 word x 16bit electrically switchable configuration

• Single +3.3V power supply

• Access time 80ns

Page mode access time 25ns

• Input / Output TTL compatible

• Three-state output

• Packages

70-pin plastic SSOP (SSOP70-P-500-0.80-K) (Product name : MR27V3255DMB)

70-pin plastic TSOP (TSOP II 70-P-400-0.65-K) (Product name : MR27V3255DTA)
