Overview

The LC374500ST is a 524288-word

× 8-bit (4M) mask

programmable ROM that is pin compatible with flash

memory. Since this product supports the wide operating

voltage range of 2.6 to 5.5 V and achieves access times of

in high-speed 5-V systems and battery-operated 3-V

systems. Since this product is pin compatible with flash

memory it can replace flash memory used during

prototyping and production.
