Very Low Power/Voltage CMOS SRAM  
256K X 8 bit  
STC  
STC62WV2568  
„ FEATURES  
• Fully static operation  
• Data retention supply voltage as low as 1.5V  
• Easy expansion with CE2, CE1, and OE options  
• Wide Vcc operation voltage : 2.4V~5.5V  
• Very low power consumption :  
Vcc = 3.0V C-grade : 22mA (@55ns) operating current  
I- grade : 23mA (@55ns) operating current  
C-grade : 17mA (@70ns) operating current  
I- grade : 18mA (@70ns) operating current  
0.3uA (Typ.) CMOS standby current  
Vcc = 5.0V C-grade : 53mA (@55ns) operating current  
I- grade : 55mA (@55ns) operating current  
C-grade : 43mA (@70ns) operating current  
I- grade : 45mA (@70ns) operating current  
1.0uA (Typ.) CMOS standby current  
„ DESCRIPTION  
The STC62WV2568 is a high performance, very low power CMOS  
Static Random Access Memory organized as 262,144 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  
0.3uA 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 (CE1), an active HIGH chip enable (CE2), and active LOW  
output enable (OE) and three-state output drivers.  
• High speed access time :  
-55  
-70  
55ns  
70ns  
The STC62WV2568 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
The STC62WV2568 is available in DICE form, JEDEC standard 32 pin  
450mil Plastic SOP, 8mmx13.4mm STSOP and 8mmx20mm TSOP.  
• Automatic power down when chip is deselected  
• Three state outputs and TTL compatible
