Description
The UC62LV4096 is a high performance, low power
CMOS Static Random Access Memory organized as 262,144
words by 16 and operates from 1.5 V 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 70ns in
1.5V operation.
Easy memory expansion is provided enable (CE\), and
active LOW output enable (OE\) and three-state output
drivers.
The UC62LV4096 has an automatic power down feature,
reducing the power consumption significantly when chip is
deselected.
The US62LV4096 is available in the JEDEC standard 44
pin TSOP (Type II) and 48 pin mini-BGA.
