2-Mbit (256 K × 8) Static RAM
2-Mbit (256 K × 8) Static RAM
Features
■
■
Functional Description
The CY62138FV30 is a high performance CMOS static RAM
organized as 256K words by 8 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. Place the device into standby mode reducing
power consumption when deselected (CE
1
HIGH or CE
2
LOW).
To write to the device, take Chip Enable (CE
1
LOW and CE
2
HIGH) and Write Enable (WE) inputs LOW. Data on the eight I/O
pins (I/O
0
through I/O
7
) is then written into the location specified
on the address pins (A
0
through A
17
).
To read from the device, take Chip Enable (CE
1
LOW and CE
2
HIGH) and Output Enable (OE) LOW while forcing Write Enable
(WE) HIGH. Under these conditions, the contents of the memory
location specified by the address pins appear on the I/O pins.
The eight input and output pins (I/O
0
through I/O
7
) are placed in
a high impedance state when the device is deselected (CE
1
HIGH or CE
2
LOW), the outputs are disabled (OE HIGH), or
during a write operation (CE
1
LOW and CE
2
HIGH and WE
LOW).
Very high-speed: 45 ns
Temperature ranges
❐
Industrial: –40 °C to 85 °C
❐
Automotive-A: –40 °C to 85 °C
Wide voltage range: 2.20 V to 3.60 V
Pin compatible with CY62138CV25/30/33
Ultra low standby power
❐
Typical standby current: 1
A
❐
Maximum standby current: 5
A
Ultra low active power
❐
Typical active current: 1.6 mA at f = 1 MHz
Easy memory expansion with CE
1
, CE
2
, and OE Features
Automatic power down when deselected
Complementary metal oxide semiconductor (CMOS) for
Optimum speed and power
Offered in Pb-free 36-ball VFBGA, 32-pin TSOP II, 32-pin
SOIC, 32-pin TSOP I and 32-pin STSOP packages
