DESCRIPTION
The BS616UV1010 is a high performance, ultra low power CMOS
Static Random Access Memory organized as 65,536 by 16 bits and
operates form a wide range of 1.9V to 3.6V supply voltage.
Advanced CMOS technology and circuit techniques provide both
high speed and low power features with maximum CMOS standby
current of 1/1.5uA at Vcc=2/3V at 85 C and maximum access time
of 100ns.
Easy memory expansion is provided by an active LOW chip enable
(CE) and active LOW output enable (OE) and three-state output
drivers.
The BS616UV1010 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS616UV1010 is available in DICE form, JEDEC standard
44-pin TSOP II and 48-ball BGA package.

PIN DESCRIPTIONS
Name
A0-A15 Address Input
CE Chip Enable Input
Function
These 16 address inputs select one of the 65,536 x 16-bit in the RAM
CE is active LOW. Chip enable must be active when data read form or write to the
device. If chip enable is not active, the device is deselected and is in 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 impendence state when OE is inactive.
