Functional Description
The CY62136V and CY62136V18 are high-performance
CMOS static RAMs organized as 131,072 words by 16 bits.
This device features advanced circuit design to provide ul-
tra-low active current. This is ideal for providing More Battery
Life (MoBL) in portable applications such as cellular tele-
phones. The device also has an automatic power-down fea-
ture that significantly reduces power consumption by 99%
when addresses are not toggling. The device can also be put
into standby mode when deselected (CE HIGH). The in-
put/output pins (I/O
0
through I/O
15
) are placed in a high-im-
pedance state when: deselected (CE HIGH), outputs are dis-
abled (OE HIGH), BHE and BLE are disabled (BHE, BLE
HIGH), or during a write operation (CE LOW, and WE LOW).
Writing to the device is accomplished by taking Chip Enable
(CE) and Write Enable (WE) inputs LOW. If Byte Low Enable
(BLE) is LOW, then data from I/O pins (I/O
0
through I/O
7
), is
written into the location specified on the address pins (A
0
through A
16
). If Byte High Enable (BHE) is LOW, then data
from I/O pins (I/O
8
through I/O
15
) is written into the location
specified on the address pins (A
0
through A
16
).
Reading from the device is accomplished by taking Chip En-
able (CE) and Output Enable (OE) LOW while forcing the Write
Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then
data from the memory location specified by the address pins
will appear on I/O
0
to I/O
7
. If Byte High Enable (BHE) is LOW,
then data from memory will appear on I/O
8
to I/O
15
. See the
Truth Table at the back of this data sheet for a complete de-
scription of read and write modes.
The CY62136V and CY62136V18 are available in 48-ball
FBGA and standard 44-pin TSOP Type II (forward pinout)
packaging.
