„ DESCRIPTION  
The STC62WV51216 is a high performance, very low power CMOS Static  
Random Access Memory organized as 524,288 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 1.5uA at 3V/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.  
• High speed access time :  
-55  
-70  
55ns  
70ns  
The STC62WV51216 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
The STC62WV51216 is available in 48B BGA and 44L TSOP2 packages.  
• Automatic power down when chip is deselected  
• Three state outputs and TTL compatible
