„ DESCRIPTION  
The STC62WV25616 is a high performance, very low power CMOS Static  
Random Access Memory organized as 262,144 words by 16 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)  
,active LOW output enable(OE) and three-state output drivers.  
The STC62WV25616 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
• High speed access time :  
-55  
-70  
55ns  
70ns  
• Automatic power down when chip is deselected  
• Three state outputs and TTL compatible  
• Fully static operation  
The STC62WV25616 is available in DICE form, JEDEC standard 44-pin  
TSOP Type II package and 48-ball BGA package.
