256K X 16 BIT LOW POWER CMOS SRAM
Rev. 1.1
FEATURES
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.
ꢀ Fast access time : 55/70/100 ns
ꢀ CMOS Low operating power
Operating current: 45/35/25mA (Icc max)
Standby current: 20 uA(TYP.) L-version
3 uA(TYP.) LL-version
The UT62L25616(I) operates from a single 2.7V ~
3.6V power supply and all inputs and outputs are fully
TTL compatible.
ꢀ Single 2.7V~3.6V power supply
ꢀ Operating temperature:
℃
℃
Industrial : -40 ~85
The UT62L25616(I) is designed for low power system
applications. It is particularly suited for use in
high-density high-speed system applications.
ꢀ All inputs and outputs TTL compatible
ꢀ Fully static operation
ꢀ Three state outputs
ꢀ Data retention voltage: 1.5V (min)
