GENERAL DESCRIPTION

The LY6212816 is a 2,097,152-bit low power CMOS static random access memory organized as 131,072 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 LY6212816 is well designed for low power application, and particularly well suited for battery back-up nonvolatile memory application. The LY6212816 operates from a single power supply of 4.5V ~ 5.5V and all inputs and outputs are fully TTL compatible
