Very Low Power CMOS SRAM
1M X 16 bit
BS616LV1611
Pb-Free and Green package materials are compliant to RoHS
n FEATURES
ŸWide VCC operation voltage : 2.4V ~ 5.5V
n DESCRIPTION
The BS616LV1611 is a high performance, very low power CMOS
Static Random Access Memory organized as 1,048,576 by 16 bits
and operates form 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 typical CMOS standby
current of 1.5uA at 3.0V/25OC and maximum access time of 55ns at
3.0V/125OC.
ŸVery low power consumption :
VCC = 3.0V
VCC = 5.0V
Operation current : 46mA (Max.)at 55ns
2mA (Max.)at 1MHz
1.5uA (Typ.) at 25 OC
Standby current :
Operation current : 115mA (Max.)at 55ns
10mA (Max.)at 1MHz
Standby current :
ŸHigh speed access time :
6.0uA (Typ.) at 25OC
Easy memory expansion is provided by an active LOW chip enable
(CE1), active HIGH chip enable (CE2) and active LOW output
enable (OE) and three-state output drivers.

55ns(Max.) at VCC=3.0~5.5V
70ns(Max.) at VCC=2.7~5.5V
ŸAutomatic power down when chip is deselected
ŸEasy expansion with CE2, CE1 and OE options
ŸI/O Configuration x8/x16 selectable by LB and UB pin.
ŸThree state outputs and TTL compatible
The BS616LV1611 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS616LV1611 is available in 48-pin TSOP Type I package and
48-ball BGA package.
ŸFully static operation, no clock, no refresh
ŸData retention supply voltage as low as 1.5V
