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 :  
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.  
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 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.
