LC374500ST Datasheet Internal Synchronization Silicon Gate 4m (524288-word X 8-bit) Mask Rom

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : EN*5610A CMOS LSI LC374500ST Internal Synchronization Silicon Gate 4M (524288-word × 8-bit) mask ROM Pin Compatible with Flash Memory Preliminary 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 (tCA) when VCC is between 4.5 and 5.5 V and 200 ns when VCC 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.
