Very Low Power/Voltage CMOS SRAM
256K X 16 bit
BSI
BS616LV4011
DESCRIPTION
FEATURES
• Very low operation voltage : 2.4 ~ 5.5V
• Very low power consumption :
The BS616LV4011 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 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 0.25uA and maximum access time of 70/100ns in 3V operation.
Easy memory expansion is provided by active LOW chip
enable(CE), active LOW output enable(OE) and three-state output
drivers.

70ns (Max.) at Vcc = 3.0V
100ns (Max.) at Vcc = 3.0V
The BS616LV4011 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV4011 is available in DICE form, JEDEC standard 44-pin
TSOP Type II package and 48-pin BGA package.
• 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 CE and OE options
• I/O Configuration x8/x16 selectable by LB and UB pin
