GENERAL DESCRIPTION
The UT62L25616(I) is a 4,194,304-bit low power
CMOS static random access memory organized as
262,144 words by 16 bits.
The UT62L25616(I) operates from a single 2.7V ~
3.6V power supply and all inputs and outputs are fully
TTL compatible.
The UT62L25616(I) is designed for low power system
applications. It is particularly suited for use in
high-density high-speed system applications.

Notes :
1. WE is HIGH for read cycle.
2. Device is continuously selected CE =VIL.
3. Address must be valid prior to or coincident with CE transition; otherwise tAA is the limiting parameter.
4. OE is LOW.
5. tCLZ, tOLZ, tCHZ and tOHZ are specified with CL = 5pF. Transition is measured ±500mV from steady state.
6. At any given temperature and voltage condition, tCHZ is less than tCLZ, tOHZ is less than tOLZ.
