UT62L2568LS-70LLI Datasheet PDF - Utron Technology Inc

GENERAL DESCRIPTION
The UT62L2568 is a 2,097,152-bit low power CMOS static random access memory organized as 262,144 words by 8 bits. It is fabricated using high performance, high reliability CMOS technology.
The UT62L2568 is designed for very low power system applications. It is particularly well suited for battery back-up nonvolatile memory applications.
It operates from a wide range of 2.5V~ 3.6V supply voltage. Easy memory expansion is provided by using two chip enable input ( CE1 ,CE2). And all inputs and three-state outputs are fully TTL compatible.
