VCC = 1.2V
y High speed access time :
-55
55ns (Max.) at VCC=3.0V
70ns (Max.) at VCC=1.8V
y Automatic power down when chip is deselected
y Easy expansion with CE1, CE2 and OE options
y Three state outputs and TTL compatible
y Fully static operation, no clock, no refresh
y Data retention supply voltage as low as 1.0V
The BH62UV8001 is a high performance, ultra low power CMOS
Static Random Access Memory organized as 1,048,576 by 8 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
O
15uA at 3.6V at 85 C and maximum access time of 55/70ns at
Vcc=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 BH62UV8001 has an automatic power down feature, reducing
the power consumption significantly when chip is deselected.
The BH62UV8001 is available in DICE form 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 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.

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.
