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.
