The BS62LV4006 is a high performance, very low power CMOS
Static Random Access Memory organized as 524,288 by 8 bits and
operates form a wide range of 2.4V to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both
high speed and low power features with typical CMOS standby
current of 0.25uA at 3.0V/25OC and maximum access time of 55ns at
3.0V/85OC.
Easy memory expansion is provided by an active LOW chip enable
(CE), and active LOW output enable (OE) and three-state output
drivers.
The BS62LV4006 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS62LV4006 is available in DICE form, JEDEC standard 32 pin
450mil Plastic SOP, 600mil Plastic DIP, 400 mil TSOP II,
8mmx13.4mm STSOP and 8mmx20mm TSOP package.

Function
A0-A18 Address Input
These 19 address inputs select one of the 524,288 x 8-bit in the RAM
CE Chip Enable Input
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.
DQ0-DQ7 Data Input/Output
There 8 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. Transition is measured ± 500mV from steady state with CL = 5pF.
The parameter is guaranteed but not 100% tested.
11. tCW is measured from the later of CE going low to the end of write.
