DESCRIPTION
The BS616LV2017 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 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
1.0uA at 5.0V /25
o
C and maximum access time of 55ns at 5.0V / 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 BS616LV2017 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV2017 is available in DICE form , JEDEC standard 44-pin
TSOP Type II package and 48-ball BGA package.

PIN DESCRIPTIONS
BS616LV2017
Name
A0-A16 Address Input
CE Chip Enable Input
Function
These 17 address inputs select one of the 131,072 x 16-bit words in the RAM.
CE is active LOW. Chip enables must be active when data read from or write to the
device. if chip enable is not active, the device is deselected and is in a standby power
mode. The DQ pins will be in the high impedance state when the device is deselected.
WE Write Enable Input
The write enable input is active LOW and controls read and write operations. With the
chip selected, when WE is HIGH and OE is LOW, output data will be present on the
DQ pins; when WE is LOW, the data present on the DQ pins will be written into the
selected memory location.
OE Output Enable Input
The output enable input is active LOW. If the output enable is active while the chip is
selected and the write enable is inactive, data will be present on the DQ pins and they
will be enabled. The DQ pins will be in the high impedance state when OE is inactive.
