¡ Semiconductor 1A MSM27C3252CZ 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 MSM27C3252CZ 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 8bit. The MSM27C3252CZ operates on a single +5V power supply and is TTL compatible. The MSM27C3252CZ provides Page mode which can greatly reduce the read access time. Since the MSM27C3252CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C3252CZ 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 48-pin TSOP packages.
