Rev. 1.3
256K X 16 BIT LOW POWER CMOS SRAM
GENERAL DESCRIPTION
The LY6225616 is a 4,194,304-bit low power CMOS static random access memory organized as 262,144 words by 16 bits. It is fabricated using very high performance, high reliability CMOS technology. Its standby current is stable within the range of operating temperature. The LY6225616 is well designed for low power application, and particularly well suited for battery back-up nonvolatile memory application. The LY6225616 operates from a single power supply of 4.5V ~ 5.5V and all inputs and outputs are fully TTL compatible
FEATURES
Fast access time : 45/55/70ns Low power consumption: Operating current : 45/40/30mA (TYP.) Standby current : 5μA@5V(TYP.) LL/SL v.
