Overview

The LC371100SP, LC371100SM and LC371100ST are 131,072-word × 8-bit organization (1,048,576-bit) mask programmable read only memories. The LC371100SP-10, LC371100SM-10 and LC371100ST-10 feature an access time of 100 ns, an OE access time of 40 ns, and a standby current of 30 µ A, and are optimal for use in 5-V systems that require high-speed access. The LC371100SP-20LV, LC371100SM-20LV and LC371100ST-20LV feature an access time of 200 ns, an OE access time of 80 ns, and a standby current of 4 µ A. Additionally, they provide high-speed access in 3.3-V systems (3.0 to 3.6 V) with a 150-ns access time and a 60ns OE access time. These ROMs adopt the JEDEC standard pin assignment which allows them to replace EPROM easily. To prevent bus line collisions in multi-bus microcontroller systems, pin 24 can be mask programmed to be either active high or active low.
