DESCRIPTION
The BH616UV1611 is a high performance, ultra low power CMOS
Static Random Access Memory organized as 1,048,576 by 16 bits
and operates in a wide range of 1.65V to 3.6V supply voltage.
Advanced CMOS technology and circuit techniques provide both
high speed and low power features with maximum standby current of
39uA at 3.6V/85 C and maximum access time of 55/70ns at
3.0V/1.8V.
Easy memory expansion is provided by an active LOW chip enable
(CE1), an active HIGH chip enable (CE2) and active LOW output
enable (OE) and three-state output drivers.
The BH616UV1611 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BH616UV1611 is made with two chips of 8Mbit SRAM by
stacked multi-chip-package.
The BH616UV1611 is available in 48-ball BGA package.

Function
These 20 address inputs select one of the 1,048,576 x 16 bit in the RAM
CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active when
data read from or write to the device. If either 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.
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.
