The BS62LV8001 is a high performance, very low power CMOS
Static Random Access Memory organized as 1,048,576 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 maximum CMOS standby
O
current of 8/50uA at Vcc=3/5V at 85 C and maximum access time of
55/70ns.
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 BS62LV8001 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BS62LV8001 is available in DICE form, JEDEC standard 44-pin
TSOP II and 48-ball BGA package.

Function
A0-A19 Address Input
These 20 address inputs select one of the 1,048,576 x 8-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 form 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
WE Write Enable Input
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.
The output enable input is active LOW. If the output enable is active while the chip is
OE Output Enable Input
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

NOTES:
1. WE must be high during address transitions.
2. The internal write time of the memory is defined by the overlap of CE1 and CE2 active 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 CE1 or WE going high or CE2 going low 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 CE1 low transition or the CE2 high 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 CE1 is low and CE2 is high 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 CE1 going low or CE2 going high to the end of write.
