Functional Description
[1]
The CY62137CV30/33 and CY62137CV are high-perfor-
mance CMOS static RAMs organized as 128K words by 16
bits. These devices feature advanced circuit design to provide
ultra-low active current. This is ideal for providing More Battery
Life (MoBL
) in portable applications such as cellular
telephones. The devices also has an automatic power-down
feature that significantly reduces power consumption by 80%
when addresses are not toggling. The device can also be put
into standby mode reducing power consumption by more than
99% when deselected (CE HIGH or both BLE and BHE are
HIGH). The input/output pins (I/O
0
through I/O
15
) are placed
in a high-impedance state when: deselected (CE HIGH),
outputs are disabled (OE HIGH), both Byte High Enable and
Byte Low Enable 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
Enable (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
description of read and write modes.
