The UT62L6416 is a 1,048,576-bit low power

CMOS static random access memory organized

as 65,536 words by 16 bits.

The UT62L6416 operates from a single 2.7V ~

3.6V power supply and all inputs and outputs are

fully TTL compatible.

The UT62L6416 is design for upper and low byte

access by data byte control( UB LB ).
