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 easyto- 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.
