MSM531632F

Semiconductor MSM531632F 1,048,576-Word x 16-Bit or 2,097,152-Word x 8-Bit MASKROM DESCRIPTION The OKI MSM531632F is a high-speed CMOS Mask ROM that can electrically switch between 1,048,576-word x 16-bit or 2,097,152-word x 8-bit configurations. The MSM531622E 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 www.DataSheet4U.com MSM531622F is suited for use as large capacity fixed memory for microcomputers and data terminals.
