BSI Very Low Power/Voltage CMOS SRAM
512K x 16 or 1M x 8 bit switchable
BS616LV8021
FEATURES
• Very low operation voltage : 2.7 ~ 3.6V
• Very low power consumption :
Vcc = 3.0V C-grade: 20mA (Max.) operating current
I-grade : 25mA (Max.) operating current
1uA (Typ.) CMOS standby current
• 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
• 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
DESCRIPTION
The BS616LV8021 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 2.7V to 3.6V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current
of 1uA 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.
The BS616LV8021 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV8021 is available in 48-pin BGA type.
