„ DESCRIPTION  
The STC62WV1024 is a high performance, very low power CMOS  
Static Random Access Memory organized as 131,072 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  
0.1uA at 3V/25oC and maximum access time of 55ns at 3V/85oC.  
Easy memory expansion is provided by an active LOW chip  
enable (CE1), an active HIGH chip enable (CE2), and active LOW  
output enable (OE) and three-state output drivers.

55ns  
70ns  
The STC62WV1024 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
The STC62WV1024 is available in DICE form , JEDEC standard 32 pin  
450mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP,8mm x13.4  
mm STSOP and 8mmx20mm TSOP.  
• Automatic power down when chip is deselected
