„ DESCRIPTION  
The STC62WV5128 is a high performance, very low power CMOS  
Static Random Access Memory organized as 524,288 words by 8 bits  
and operates from a wide range of 2.4V to 5.5V supply voltage.  
Advanced CMOS technology and circuit techniques provide both high  
speed and low power features with a typical CMOS standby current of  
0.45uA at 3.0V/25oC and maximum access time of 55ns at 3.0V/85oC.  
Easy memory expansion is provided by an active LOW chip enable  
(CE) , and active LOW output enable (OE) and three-state output  
drivers.  
• High speed access time :  
-55  
-70  
55ns  
70ns  
The STC62WV5128 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
The STC62WV5128 is available in the JEDEC standard 32L SOP, TSOP  
, PDIP, TSOP II and STSOP package.  
• Automatic power down when chip is deselected  
• Fully static operation
