Low Power CMOS SRAM

128K X 8 Bits

UC62LS1008

-20/-25

Features:

• Vcc operation voltage :

3.0V~ 3.6V

• Low power consumption :

20mA (Max.) operating current

1uA (Typ.) CMOS standby current

• High Speed Access time :

25ns (Max.) at Vcc = 3.0V

• Easy expansion with CE\ and OE\ options

Description

The UC62LS1008 is a high performance, very low power

CMOS Static Random Access Memory organized as 131,072

words by 8 bits and operates from

3.0V to 3.6V supply

voltage. Advanced CMOS technology and circuit techniques

provide both high speed and low power features with a

typical CMOS standby current of 1uA and maximum access

time of 25ns in 3.0V operation.

Easy memory expansion is provided enable (CE\), and

active LOW output enable (OE\) and three-state output

drivers.

The UC62LS1008 has an automatic power down feature,

reducing the power consumption significantly when chip is

deselected.

The UC62LS1008 is available in the JEDEC standard 32 pin

450mil

Plastic SOP,

8mmx20.0mm

TSOP (type I), and

8mmx13.4mm STSOP.
