„ DESCRIPTION
The BS616LV4018 is a high performance, very low power CMOS Static
Random Access Memory organized as 262,144 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
2.0uA at 5.0V/25oC and maximum access time of 55ns at 5.0V/85oC.
Easy memory expansion is provided by an active LOW chip enable (CE)
,active LOW output enable(OE) and three-state output drivers.
The BS616LV4018 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV4018 is available in DICE form , JEDEC standard 44-pin
TSOP Type II package and 48-ball BGA package.

A0-A17 Address Input
These 18 address inputs select one of the 262,144 x 16-bit words in the RAM.
CE Chip Enable Input
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.
LB and UB Data Byte Control Input
Lower byte and upper byte data input/output control pins.
DQ0 - DQ15 Data Input/Output

These 16 bi-directional ports are used to read data from or write data into the RAM.

NOTES:
1. WE must be high during address transitions.
2. The internal write time of the memory is defined by the overlap of CE and WE low. All signals
must be active to initiate a write and any one signal can terminate a write by going inactive.
The data input setup and hold timing should be referenced to the second transition edge of
the signal that terminates the write.
3. TWR is measured from the earlier of CE or WE going high at the end of write cycle.
4. During this period, DQ pins are in the output state so that the input signals of opposite phase
to the outputs must not be applied.
5. If the CE low transition occurs simultaneously with the WE low transitions or after the WE
transition, output remain in a high impedance state.
6. OE is continuously low (OE = VIL ).
7. DOUT is the same phase of write data of this write cycle.
8. DOUT is the read data of next address.
9. If CE is low during this period, DQ pins are in the output state. Then the data input signals of
opposite phase to the outputs must not be applied to them.
10. TCW is measured from the later of CE going low to the end of write.
11. The parameter is guaranteed but not 100% tested.
