Internal Synchronization Silicon Gate 4M (524288-word
× 8-bit) mask ROM Pin Compatible with Flash Memory
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
100 ns (t_CA) when V_CC is between 4.5 and 5.5 V and 200
ns when V_CC is between 2.6 and 5.5 V, it can be used both
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.
