DESCRIPTION
The BH616UV4010 is a high performance, ultra low power CMOS
Static Random Access Memory organized as 262,144 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 typical operating current of
1.5mA at 1MHz at 3.6V/25
O
C and maximum access time of 55ns at
1.65V/85
O
C.
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 BH616UV4010 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BH616UV4010 is available in DICE form, JEDEC standard
48-pin TSOP-I and 48-ball BGA package.

PIN DESCRIPTIONS
Name
Function
A0-A17 Address Input
These 18 address inputs select one of the 262,144 x 16 bit in the RAM
CE1 Chip Enable 1 Input
CE2 Chip Enable 2 Input
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.
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.
LB and UB Data Byte Control Input
Lower byte and upper byte data input/output control pins.
DQ0-DQ15 Data Input/Output
Ports
16 bi-directional ports are used to read data from or write data into the RAM.

1. Stresses greater than those listed under ABSOLUTE
MAXIMUM RATINGS may cause permanent damage to the
device. This is a stress rating only and functional operation of
the device at these or any other conditions above those
indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
