1 2,097,152-word x 16-bit or 4,194,304-word x 8-bit maskrom description the oki MSM533222E is a high-speed cmos mask rom that can electrically switch between 2,097,152-word x 16-bit or 4,194,304-word x 8-bit configurations. the MSM533222E operates on a single 5.0v power supply and is ttl compatible. the chip's asynchronous i/o requires no external clock assuring easy operation. a power-down mode provides low power dissipation when the chip is not selected. the ce and oe pins are provided as control signals that permit three-stated output allowing easy memory expansion on a system bus.the MSM533222E is suited for use as large capacity fixed memory for microcomputers and data terminals. features single 5.0v power supply 2,097,152-words x 16-bit/4,194,304-words x 8-bit access time 100ns max input/output ttl compatible tri-state output configurations internal powerdown function packages: 44-pin plastic sop (sop44-p-600-k) 48-pin plastic tsop (tsop48-p-550-k) MSM533222E semiconductor
