The MR27V3255D is a 32Mbit electrically Programmable Read-Only Memory with page mode. It 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.
The MR27V3255D is a 32Mbit electrically Programmable Read-Only Memory (PROM) featuring page mode operation. Its configuration can be electrically switched between 1,048,576 double word x 32-bit and 2,097,152 word x 16-bit modes. The device operates on a single +3.3V power supply and is TTL compatible, making it suitable as large-capacity fixed memory for microcomputers and data terminals.
