| Ordering number : EN*5087C CMOS LSI LC371100SP, SM, ST-10/20LV 1 MEG (131072 wordsx 8 bits) Mask ROM Internal Clocked Silicon Gate Preliminary Overview The LC371100SP, LC371100SM and LC371100ST are 131,072-word x 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 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 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.

As a result, the output data immediately after power on is invalid. Once power has been applied, valid data is output after the application changes the value of either the CE input or at least one of the address inputs. Another point due to the use of the ATD technique is that these LSIs are extremely sensitive to input noise. Applications must take precautions to provide stable input signals, both for the CE input and the address inputs, to prevent incorrect operation. s No products described or contained herein are intended for use in surgical implants, life-support systems, aerospace equipment, nuclear power control systems, vehicles, disaster/crime-prevention equipment and the like, the failure of which may directly or indirectly cause injury, death or property loss. s Anyone purchasing any products described or contained herein for an above-mentioned use shall: Accept full responsibility and indemnify and defend SANYO ELECTRIC CO., LTD., its affiliates, subsidiaries and distributors and all their officers and employees, jointly and severally, against any and all claims and litigation and all damages, cost and expenses associated with such use: Not impose any responsibility for any fault or negligence which may be cited in any such claim or litigation on SANYO ELECTRIC CO., LTD., its affiliates, subsidiaries and distributors or any of their officers and employees jointly or severally. s Information (including circuit diagrams and circuit parameters) herein is for example only; it is not guaranteed for volume production.
