Overview
Semiconductor 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.
