¡ Semiconductor 1A MR27V3252D 2,097,152-Word x 16-Bit or 4,194,304-Word x 8-Bit 8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM DESCRIPTION The MR27V3252D is a 32Mbit electrically Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 2,097,152 word x 16bit and 4,194,304 word x 8 bit. The MR27V3252D operates on a single +3.3V power supply and is TTL compatible. The MR27 V3252D provides Page mode which can greatly reduce the read access time. Since the MR27V3252 D operates asynchronously , external clocks are not required , making this device easy-to-use. The MR27V3252D 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 44-pin SOP or 48pin TSOP packages.
