MSM538002E
524,288-Word x 16-Bit or 1,048,576-Word x 8-Bit MASKROM
DESCRIPTION
The OKI MSM538002E is a high-speed CMOS Mask ROM that can electrically switch
between 524,288-word x 16-bit or 1,048,576-word x 8-bit configurations. The MSM538002E
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
MSM538002E is suited for use as large capacity fixed memory for microcomputers and data
terminals.
