Very Low Power/Voltage CMOS SRAM
1M x 16 or 2M x 8 bit switchable

The BS616LV1626 is a high performance, very low power CMOS Static
Random Access Memory organized as 1,048,676 words by 16 bits or
2,097,152 bytes by 8 bits selectable by CIO pin and operates in a Vcc
range of 4.5V 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 15uA at 5.0V/25
o
C and maximum access time of 55ns at 5.0V/85
o
C .
This device provide three control inputs and three states output drivers
for easy memory expansion.
The BS616LV1626 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV1626 is available in 48-pin 12mmx20mm TSOP1 package.
