Very Low Power/Voltage CMOS SRAM  
512K x 16 or 1M x 8 bit switchable  
BSI  
BS616LV8022  
„ FEATURES  
„ DESCRIPTION  
• Very low operation voltage : 2.4 ~ 5.5V  
• Very low power consumption :  
The BS616LV8022 is a high performance, very low power CMOS Static  
Random Access Memory organized as 524,288 words by 16 bits or  
1,048,576 bytes by 8 bits selectable by CIO pin and operates from a wide  
range of 2.4V to 5.5V supply voltage.  
Vcc = 3.0V C-grade: 20mA (Max.) operating current  
I-grade : 25mA (Max.) operating current  
0.5uA (Typ.) CMOS standby current  
Vcc = 5.0V C-grade: 45mA (Max.) operating current  
I-grade : 50mA (Max.) operating current  
3uA (Typ.) CMOS standby current  
Advanced CMOS technology and circuit techniques provide both high  
speed and low power features with a typical CMOS standby current  
of 0.5uA and maximum access time of 70/100ns in 3.0V operation.  
Easy memory expansion is provided by an active HIGH chip  
enable2(CE2), active LOW chip enable1(CE1), active LOW output  
enable(OE) and three-state output drivers.  
• High speed access time :  
-70  
70ns (Max.) at Vcc= 3.0V  
-10 100ns (Max.) at Vcc= 3.0V  
• Automatic power down when chip is deselected  
• Three state outputs and TTL compatible  
• Fully static operation  
The BS616LV8022 has an automatic power down feature, reducing the  
power consumption significantly when chip is deselected.  
The BS616LV8022 is available in 48-pin BGA type.  
• Data retention supply voltage as low as 1.5V  
• Easy expansion with CE1, CE2 and OE options  
• I/O Configuration x8/x16 selectable by CIO, LB and UB pin
