www.DataSheet4U.com ¡ Semiconductor MSM27C3255CZ 1,048,576-Double Word x 32-Bit or 2,097,152-Word x 16-Bit 4-Double Word x 32-Bit or 8-Word x 16-Bit Page Mode One Time PROM DESCRIPTION 1A The MSM27C3255CZ 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 MSM27C3255CZ operates on a single +5V power supply and is TTL compatible. The MSM27C3255CZ provides Page mode which can greatly reduce the read access time. Since the MSM27C3255CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C3255CZ 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 package.
