CY62128EV30 MoBL 1-Mbit (128K 8) Static RAM 1-Mbit (128K 8) Static RAM Features Functional Description Very high speed: 45 ns The CY62128EV30 is a high performance CMOS static RAM module organized as 128K words by 8-bits. This device features Temperature ranges: advanced circuit design to provide ultra low active current. This Industrial: 40 C to +85 C is ideal for providing More Battery Life (MoBL ) in portable applications such as cellular telephones. The device also has an Wide voltage range: 2.2 V to 3.6 V automatic power-down feature that significantly reduces power Pin compatible with CY62128DV30 consumption when addresses are not toggling. Placing the device in standby mode reduces power consumption by more Ultra low standby power than 99 percent when deselected (CE HIGH or CE LOW). The 1 2 Typical standby current: 1 A eight input and output pins (I/O through I/O ) are placed in a 0 7 Maximum standby current: 4 A high impedance state when the device is deselected (CE HIGH 1 or CE LOW), the outputs are disabled (OE HIGH), or a write 2 Ultra low active power operation is in progress (CE LOW and CE HIGH and WE 1 2 Typical active current: 1.3 mA at f = 1 MHz LOW). Easy memory expansion with CE , CE and OE features 1 2, To write to the device, take chip enable (CE LOW and CE 1 2 HIGH) and write enable (WE) inputs LOW. Data on the eight I/O Automatic power-down when deselected pins is then written into the location specified on the address pin Complementary metal oxide semiconductor (CMOS) for (A through A ). 0 16 optimum speed and power To read from the device, take chip enable (CE LOW and CE 1 2 Offered in Pb-free 32-pin small outline integrated circuit (SOIC), HIGH) and output enable (OE) LOW while forcing write enable 32-pin thin small outline package (TSOP) Type I, and 32-pin (WE) HIGH. Under these conditions, the contents of the memory shrunk thin small outline package (STSOP) packages location specified by the address pins appear on the I/O pins.
