„ DESCRIPTION
The BS616LV2018 is a high performance, very low power CMOS Static
Random Access Memory organized as 131,072 words by 16 bits and
operates from a wide range of 2.4V 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 0.1uA and maximum access time of 70ns in 3V operation.
Easy memory expansion is provided by active LOW chip
enable(CE), active LOW output enable(OE) and three-state output
drivers.
The BS616LV2018 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV2018 is available in DICE form, JEDEC standard 48-pin
TSOP Type I package and 48-ball BGA package.
