R0201-BS616LV2019
Very Low Power/Voltage CMOS SRAM
128K X 16 bit
• Vcc operation voltage range : 2.7V ~ 3.6V
• Very low power consumption :
Vcc = 3.0V C-grade: 23mA (@55ns) operating current
I -grade: 25mA (@55ns) operating current
C-grade: 15mA (@70ns) operating current
I -grade: 16mA (@70ns) operating current
0.3uA(Typ.) CMOS standby current
• High speed access time :
-55 55ns
-70 70ns
• 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
The BS616LV2019 is a high performance , very low power CMOS Static
Random Access Memory organized as 131,072 words by 16 bits and
operates from a 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
0.3uA at 3.0V/25
o
C and maximum access time of 55ns at 2.7V/85
o
C.
Easy memory expansion is provided by active LOW chip enable (CE),
active LOW output enable(OE) and three-state output drivers.
The BS616LV2019 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV2019 is available in DICE form , JEDEC standard 48-pin
TSOP Type I package and 48-ball BGA package.
