ꢀDescription
The UC62LS2048 is a high performance, low power
CMOS Static Random Access Memory organized as 131,072
words by 16 and operates from 3.0 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 1uA and maximum access time of 25ns in
3.0V operation.
25ns (Max.) at Vcc = 3.0V
• Automatic power down when chip is deselected
• Three state outputs and TTL compatible
• Data retention supply voltage as low as 1.2V
• Easy expansion with CE\ and OE\ options
Easy memory expansion is provided enable (CE\), and
active LOW output enable (OE\) and three-state output
drivers.
The UC62LS2048 has an automatic power down feature,
reducing the power consumption significantly when chip is
deselected.
The US62LS2048 is available in the JEDEC standard 44
pin TSOP (Type II) and 48 pin mini-BGA.
