Semiconductor MSM534032E 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.
