MSM534002E

262,144-Word x 16-Bit or 524,288-Word x 8-Bit MASKROM

DESCRIPTION

The OKI MSM534002E is a high-speed CMOS Mask ROM that can electrically switch

between 262,144-word x 16-bit and 524,288-word x 8-bit configurations. The MSM534002E

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 MSM534002E is suited for use as large capacity fixed memory for microcomputers and

data terminals.
