Low Power CMOS SRAM  
128K X 16  
UC62LS2048  
-20/-25  
Features:  
• Vcc operation voltage : 3.0 V~ 3.6V  
• Low power consumption :  
20mA (Max.) operating current  
1uA (Typ.) CMOS standby current  
• High Speed Access time :  
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.
