MSM534031E

524,288-Word x 8-Bit MASKROM

DESCRIPTION

The OKI MSM534031E is a high-speed silicon gate CMOS Mask ROM with 524,288-word x
8-bit capacity. The MSM534031E operates on a single 3.0V or 3.3V power supply but offers
the same fast access times as products that operate at 5.0V. The MSM534031E's 8-bit wide

data path and pin compatibility with UV erasable EPROMs make it suited for use as large
capacity fixed memory for portable microcomputers and data terminals.
