CY62135V18 MoBL2™
128K x 16 Flash Compatible Static RAM
Features
• Low voltage range:
— CY62135V: 2.7V–3.3V
— CY62135V18: 1.65–1.95V
• Ultra-low active/standby power
• Easy memory expansion with CE /CE2 and OE features
• Automatic power-down when deselected
• Pin out compatible with standard Flash devices
• Shipped in Wafer/Die form
BHE are HIGH
[1]
. The input/output pins (I/O
0
through I/O
15
)
are placed in a high-impedance state when: deselected (CE
HIGH or CE2 LOW), outputs are disabled (OE HIGH), BHE
and BLE are disabled (BHE, BLE HIGH), or during a write
operation (CE LOW, CE2 HIGH and WE LOW).
Writing to the device is accomplished by taking chip enable
(CE) LOW, CE2 HIGH, 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 ad-
dress 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) LOW, CE2 HIGH, 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.
The CY62135V/CY62135V18 are shipped in a wafer form.
Functional Description
The CY62135V and CY62135V18 are high-performance
CMOS static RAMs organized as 128K words by 16 bits. This
device features 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 device also has an automatic power-down feature that
significantly reduces power consumption by 99% when ad-
dresses are not toggling. The device can also be put into
standby mode when deselected (CE HIGH or CE2 LOW) or
when CE is LOW and when CE2 is HIGH and both BLE and
