262,144-Word x 16-Bit or 524,288-Word x 8-Bit MASKROM

DESCRIPTION

The OKI MSM534032E is a high-speed CMOS Mask ROM that can electrically switch

between 262,144-word x 16-bit and 524,288-word x 8-bit configurations. The MSM534032E

operates on a single 3.0V or 3.3V power supply but offers the same fast access times as

products operating at 5.0V. The MSM534032E's applied byte system and pin compatibility

with UV erasable EPROMs make it ideally suited as large capacity read-only memory for

portable microcomputers and data terminal equipment. Optional products with 2.7V~5.5V

operating parameters are also available.
