CY62128EV30

CY62128EV30 MoBL® 1-Mbit (128K × 8) Static RAM 1-Mbit (128K × 8) Static RAM Features ■ Very high speed: 45 ns ■ Temperature ranges: ❐ Industrial: –40 °C to +85 °C ■ Wide voltage range: 2.2 V to 3.6 V ■ Pin compatible with CY62128DV30 ■ Ultra low standby power ❐ Typical standby current: 1 µA ❐ Maximum standby current: 4 µA ■ Ultra low active power ❐ Typical active current: 1.3 mA at f = 1 MHz ■ Easy memory expansion with CE1, CE2, and OE features ■ Automatic power-down when deselected ■ Complementary metal oxide semiconductor (CMOS) for optimum speed and power ■ Offered in Pb-free 32-pin small outline integrated circuit (SOIC), 32-pin thin small outline package (TSOP) Type I, and 32-pin shrunk thin small outline package (STSOP) packages Functional Description The CY62128EV30 is a high performance CMOS static RAM module organized as 128K 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 when addresses are not toggling. Placing the device in standby mode reduces power consumption by more than 99 percent when deselected (CE1 HIGH or CE2 LOW). The eight input and output pins (I/O0 through I/O7) are placed in a high impedance state when the device is deselected (CE1 HIGH or CE2 LOW), the outputs are disabled (OE HIGH), or a write...
