MSM538032E

Semiconductor MSM538032E 524,288-Word x 16-Bit or 1,048,576-Word x 8-Bit MASKROM DESCRIPTION The OKI MSM538032E is a high-speed CMOS Mask ROM that can electrically switch between 524,288-word x 16-bit and 1,048,576-word x 8-bit configurations. The MSM538032E operates on a single 3.0V or 3.3V power supply but offers access times equivalent to products operating at 5.0V. The MSM538032E'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 2.7~5.5V operating parameters are also available.
