BS616LV4015  
„ DESCRIPTION  
„ FEATURES  
The BS616LV4015 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 4.5V 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 and maximum access time of 55ns in 5V operation.  
Easy memory expansion is provided by an active LOW chip  
enable(CE) and active LOW output enable(OE) and three-state output  
drivers.  
• Operation voltage : 4.5 ~ 5.5V  
• Low power consumption :  
Vcc = 5.0V  
C-grade: 45mA (Max.) operating current  
I-grade: 50mA (Max.) operating current  
1.5uA (Typ.) CMOS standby current  
• High speed access time :  
-70  
-55  
70ns (Max.) at Vcc = 5.0V  
55ns (Max.) at Vcc = 5.0V  
• Automatic power down when chip is deselected  
• Three state outputs and TTL compatible  
• Fully static operation  
The BS616LV4015 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
The BS616LV4015 is available in DICE form, JEDEC standard 44-pin  
TSOP Type II package and 48-pin BGA package.  
• Data retention supply voltage as low as 2V  
• Easy expansion with CE and OE options  
• I/O Configuration x8/x16 selectable by LB and UB pin
