DESCRIPTION
The OKI MSM53V1655F is a 524,288-double words x 32-bit or 1,048,576-words x 16-bit
CMOS Mask ROM with an asynchronous page read mode. Each page is organized 4double
words x 32-bit or 8 words x 16-bit. It operates on a single 3.3V 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 MSM531655F is suited for use as large capacity
fixed memory for microcomputers and data terminals.
