MSM531632F
1,048,576-Word x 16-Bit or 2,097,152-Word x 8-Bit MASKROM
DESCRIPTION
The OKI MSM531632F is a high-speed CMOS Mask ROM that can electrically switch
between 1,048,576-word x 16-bit or 2,097,152-word x 8-bit configurations. The MSM531622E
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
MSM531622F is suited for use as large capacity fixed memory for microcomputers and data
terminals.
