The MR27V852D is an 8Mbit electrically Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 524,288 word x 16bit and 1,048,576 word x 8bit. The MR27V852D operates on a single +3.3V power supply and is TTL compatible. The MR27V852D provides Page mode which can greatly reduce the read access time. Since the MR27V852D operates asynchronously, external clocks are not required, making this device easy-to-use. The MR27V852D 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 42-pin DIP, 44-pin SOP or 44-pin TSOP packages.
