Description

The UC62LV2008 is a high performance, very low power

CMOS Static Random Access Memory organized as 524,288

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 2uA 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 UC62LS4008 has an automatic power down feature,

reducing the power consumption significantly when chip is

deselected.

The UC62LS4008 is available in the JEDEC standard 32

pin 450mil Plastic SOP, 8mmx20.0mm TSOP (type I),

and 8mmx13.4mm STSOP.
