DESCRIPTION
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.
