Single 5.0V power supply

The OKI MSM531652F is a 1,048,576-words x 16-bit or 2,097,152-bytes x 8-bit CMOS
Mask ROM with an asynchronous page read mode. Each page is organized 16 words x 16-
bit or 32bytes x 8-bit. It 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 MSM531652F is suited for use as large capacity fixed memory for
microcomputers and data terminals.
